<p>It is impossible to use bacteriophages and to develop a detection device if we do not know what are the needs and the constraints in hospitals and in medical analysis laboratory.  
 
So we need to discuss our project with physicians, specialists and even with the whole population. We also developed partnerships with local research laboratories and companies, to borrow equipment, recover bacteria and bacteriophages, and, most important, ask them for advice.

<p>Dr. Max Maurin notes that in the last few years, he had to face new therapeutic dead-ends caused by the antibiotic resistance that did not exist before. The issue of antibiotic resistance is, in fact, a major issue that we should urgently address. Pseudomonas is a pathogen that he encounters quite often in his department. It is not too virulent but it has numerous resistance mechanisms. According to Dr. Maurin, phage therapy is a very interesting alternative even if it arises some ethical unsolved issues and can also cause a resistance of the bacteria toward phages. The use of bacteriophages in a medical establishment seems feasible because a few years ago, viruses were already used in the biological laboratory of hospitals.  </p><p>

<p>

Dr. Maurin thinks that our system is very interesting and answers well the given problem. However, some biological risks have to be taken into account such as the dissemination of the system components. If these aspects are well evaluated and handled, the system is very promising. Yet, Dr. Morin thinks that it will be very difficult to play on the sensitivity and the specificity of our system to compete with today’s methods in molecular biology. Among all the different specificities of our system, it is mostly the bacteriophages selection that caught his attention the most.</p><p>

<p><b><i>Do you often encounter antibiotic-resistant bacteria in your department?</i></b></p>
 
<p><b><i>Do you often encounter antibiotic-resistant bacteria in your department?</i></b></p>
  
 +
<p>This is a current issue. There are a lot of new resistant bacteria. Most of my activities are centered on the subject. It includes antibiotic resistance characterization and antibiotic efficiency prognosis. <br>
 +
“It is not a new issue.”<br>
 +
In the hospital, antibiotics are used a lot and there is an emergence of poly resistant bacteria strains. The industry did not succeed in developing antibiotics to remedy to the resistance issues. The bacteria won.<br>
 +
“There are many strains that became resistant to most of the antibiotics” so “the therapeutic possibilities decreased little by little”.<br>
 +
“It is a real issue for public health” but we know how to treat most of the cases though.
 +
“There is an emergence of of therapeutic dead-ends in the hospital, that we we did not see since long time ago. People have infections with zero treatment possible to cure them, that is rare.” <br>
 +
“Each year, new resistances emerge and we see their prevalence increasing. That is a reality.”
 +
</p>
 +
 +
<p><b><i>Do cases of Pseudomonas aeruginosa infections represent a large percentage of infections?</i></b></p>
 +
<p>It is a significant pathogen, even though initially not very virulent. In the hospitals it is an issue for weakened people (immunosuppressed people, or in extended care). It is an hospital pathogen. “This strain has a lot of facilities to acquire new resistances”.
 +
</p>
 +
 +
<p><b><i>Do you know phage therapy? If so, what do you think?</i></b></p>
 +
<p> There are difficulties to find the good bacteriophages, the not pathogenic ones.<br>
 +
Ethical problems persist. Resistance problems still persist. Bacteriophages are an interesting concept but should be used as a last resort. <br>
 +
There are also new alternatives like anti-virulence drugs to prevent the virulence of bacteria but not their growth. “They are less selective molecules that act on virulence factors without killing them”. It can be used as a treatment by itself or to associate with antibiotics.<br>
 +
Some drugs to boost immune defenses also exist.
 +
</p>
 +
 +
<p><b><i>Is it possible to manipulate phages in your service (ours and generally speaking), are there specific safety rules?
 +
</i></b></p>
 +
<p>Viruses were used in the past for typing in molecular biology labs in hospitals.<br>
 +
However many regulations are necessary for the drugs and even more for “living” drugs. There is an additional constraint not to infect the patients and the medical staff. There is a fear that viruses could transmit the resistances (horizontal transfer).
 +
</p>
 +
 +
<p><b><i>Is it possible to handle modified E.Coli in your department (problem of horizontal gene transfer)?
 +
</i></b></p>
 +
<p>Maybe special authorisations are needed since they are GMOs. At least a declaration is mandatory.
 +
<br>
 +
<p><b><i>What are the diagnostic tools available in your service to detect pathogenic bacteria (and for Pseudomonas especially) ? How much time is needed to provide a diagnostic ? With which reliability (specificity and sensibility) ? What is the prices of those devices (price of the machine and price of diagnostic per patient) ? According to you, what are the qualities of a good diagnostic device adapted to the hospitals ?
 +
</i></b></p>
 +
<p>2 main classes of tools are available in my service:<br>
 +
1) Isolation with bacterial culture which allows the identification of bacteria and the characterization (antibiotics activity and efficacy against the strain.)<br>
 +
If it is too complex or if we need to be faster :<br>
 +
2) All that includes Biochemical Methods: PCR (PCR in real time -qPCR-). Research for a pathogen.
 +
<br>About the sensibility, PCR is the less risky technic regarding to the sample contamination (between them). It is the most reliable technic and it is very fast (1 to 2 hours). Sequencing is a bit long because it has to be sent out of the hospital so it requires about 3 days or more.<br>
 +
Example : Isolation + antimicrobial susceptibility testing for Pseudomonas and resistance origin identification. If we want more details (carbapenemase type…) the most adapted will be qPCR. Of course ,the method used must be adapted according to the case complexity and the time available.<br>
 +
He estimates that nowadays in the university hospital center the repartition of the methods used is about:<br>
 +
- 90% of antimicrobial susceptibility testing and phenotypic methods<br>
 +
- 10% of Molecular Biology</p>
 +
 +
<p><b><i>If not mentioned previously: Do you have an antibiogram? How long does it take to make a diagnosis?
 +
</i></b></p>
 +
<p>Isolation and antimicrobial susceptibility testing represent 90% of analyses. They are relatively reliable. If the phenotype does not allow to get all the information needed, we switch to molecular biology methods.<br>
 +
So molecular biology in real time represents 10% of analyses. In particular cases there is not any tool available, if new resistance mechanisms appear, we can obtain false positives due to contamination. Still the reliability of real time molecular biology remains good and adapted to the complexity and the need to act quickly.
 +
</p>
 +
<br>
 +
 +
 +
<p><b><i>System overview. Do you think at first sight that it meets the security criteria of the service? Other remarks?</i></b></p>
 +
<p>The two main risks for the system are :<br>
 +
1- Biological risk (for the medical staff), pathogen classification (here P2 but not too serious, in particular for healthy people, so there is no epidemic risk)<br>
 +
2- GMO risk, we have to evaluate the diffusion and dissemination risks for us and find how to treat the contaminated waste.
 +
</p>
 +
 +
<p><b><i>How are biological waste managed in your service? Is the waste management of our kit manageable in your service? In the hospital?</i></b></p>
 +
<p>We use Citybac&reg; DASRI to throw the infection-risk waste and then everything is incinerated. Water is treated before being dumped.
 +
</p>
 +
<br>
 +
 +
<p><b><i>Did you have any bioethics training during your studies or after your studies?
 +
</i></b></p>
 +
<p>No, he learned on the job. He never got any specific formation on the subject. Some colleagues got teachings in other formations.
 +
</p>
 +
 +
<p><b><i>If no, do you think that bioethics training is missing in your learning?
 +
</i></b></p>
 +
<p>YES, the regulation is really constraining in medicine, a formation on bioethical laws should be dispensed at the beginning. Doctors are each day more led to have ethical reflexions but can definitely do better. Some people have the knowledge but the majority is not up to date on the regulation and recent laws.

<br>
 
<br>
<p>Each day, Pr. Olivier Epaulard is confronted with patients suffering from diseases caused by resistant bacteria. According to him, a misuse of antibiotics is the cause of 90% of the resistances and one antibiotic treatment out of two is wrongly prescribed. The number of antibiotic resistances does not cease to grow, like the number of immunosuppressed patients. Therefore, antibiotic resistance is a major issue of our century. Pseudomonas is also a pathogen that he encounters quite often in his department. Pr. Epaulard cannot make up his mind on the subject of phage therapy because he does not understand why it is not more developed. The positive aspect of this alternative is that bacteriophages destroy all bacteria - even the inactive ones -, something that antibiotics cannot do. According to him, the use of bacteriophages inside his department would not cause any issue. </p>
+
 
 
<p>Pr. Epaulard thinks that the project is very interesting. He is not overly passionate about the identification aspect but rather by the therapy aspect of the project.

<p>Pr. Epaulard thinks that the project is very interesting. He is not overly passionate about the identification aspect but rather by the therapy aspect of the project. The diagnostic tools he uses have already very good specificity and sensitivity. It is going to be hard to compete with them. He verified many aspects of the biology in the system and was pleased with our answers. </p>
 
<p>Pr. Epaulard thinks that one can learn about bioethics through practice. Therefore, there is no need for more theoretical courses on ethics in a physician formation.</p>

<p><b><i>Did you know about iGEM before I told you about it?</i></b></p>
 
<p><b><i>Did you know about iGEM before I told you about it?</i></b></p>
 +
<p>No.</p>
 +
 +
<p><b><i>Do you often encounter antibiotic resistant bacteria in your department ?</i></b></p>
 +
<p>Daily. Every day, all the time. They are the result of antibiotics misuse (about 90% of the cases). He estimates that half of antibiotic treatments are wrongly prescribed. According to a study, half of the doctors antibiotic prescriptions are useless. Antibiotic resistant bacteria  are enterobacteria in majority. The resistances are due to penicillinase (and other beta-lactamase / enzymes). The number of infections with resistance keeps increasing.<br>
 +
Although rare, there are cases of infection for which no treatment is possible (no antibiotic is able to kill the bacteria which resistant to everything). Some countries like India, Greece, Turkey and some african countries are at a critical stage. They are not anymore trying to manage the use of antibiotics but they are looking for methods to treat patients infected by bacteria resistant to nearly all the antibiotics.<br>
 +
Resistances appear on strains that were sensible to everything in the past. Antibiotics come from mushrooms (penicillium, ...). They are very old molecules, and that explains why bacteria can have facilities to become resistant.
 +
To reverse the process of antibiotics abusive utilisation is very complicated and hard to impulse (in particular concerning the education of the population and of practitioners).
 +
→ Analogy with the global warming: The majority knows but it requires strong behaviour changes not realized. Is it too late ? Resistance of Gram bacilli - like <i>Pseudomonas</i> - increases.<br>
 +
Nowadays, more and more people are immunosuppressed (But they would be dead before without treatment. Often, the immunosuppression comes from a heavy treatment) or go through treatments exposing them to bacteria for a long or excessive duration. For example immunosuppression for grafts or surgeries are more and more risky since they are open doors to infections. On another hand, exposition to bacteria is more and more common because of the treatments lengthening.
 +
</p>
 +
 +
<p><b><i>Do cases of Pseudomonas aeruginosa infections represent a large percentage of infections?</i></b></p>
 +
<p>Concerning common infections, we meet rarely Pseudomonas aeruginosa in general but it is present in the hospital infections in the operating rooms for patients that have a catheter in a vein, a contact with material, or a urinary infection.</p>
 +
 +
<p><b><i>Do you know Phage Therapy ? If so, what do you think ?</i></b></p>
 +
<p>Yes. He can not have a precise idea. On paper, he is enthousiast to this idea. Moreover phages seem to be easy to produce. While antibiotics can lead to intestinal flora diseases during their ingestion, phages can avoid that. In the case of chronic infections on prosthesis, to change the material is the only way to cure the infection… The phage therapy could also be a way to clean the medical material. <br>
 +
But he feels like it has been 15 years that he is hearing about phages and that nothing happens. He thinks that there are maybe other problems in the utilization of phages than<br> just the patent problematic, finally a not so important matter according to him.
 +
Indeed, in France modified viruses have been patented, a modified bacterium could be patented, so patenting a living organism is possible,... Hence, why not the phages ? One advantage of the phage is their permanent efficacy on the bacteria. Indeed antibiotics are effective only on growing bacteria. However it is the case for infections such as pneumonia and urinary infections but not long ones like bones infection for which the phage utilization would be very interesting. <br>
 +
Russia and Georgia tell that they produce phages in GMP (good manufacturing practice) but with which purity ? Which vivacity ?<br>
 +
Interesting book: “La Phagothérapie - Des virus pour combattre les infections “ Alain Dublanchet
 +
</p>
 +
 +
<p><b><i>Is it possible to manipulate phages in your service (ours + in general), are there specific safety rules?</i></b></p>
 +
<p>Yes !! No particular problem.</p>
 +
 +
<p><b><i>Is it possible to handle modified E.Coli in your department (problem of horizontal gene transfer)?</i></b></p>
 +
<p>Not any problem, everybody manipulate bacteria with plasmid containing resistance/selection genes. The evacuation system is ok and allow to avoid any crossing and to spread bacteria in the environment.
 +
</p>
 +
<br>
 +
 +
<p><b><i>What are the diagnostic tools available in your service to detect pathogenic bacteria (and for Pseudomonas especially) ? How much time is needed to provide a diagnostic ? With which reliability (specificity and sensibility) ? What is the prices of those devices (price of the machine and price of diagnostic per patient) ? According to you, what are the qualities of a good diagnostic device adapted to the hospitals ?</i></b></p>
 +
<p>The tools available in my service are multiplex PCR (not very efficient), targeted PCR, 16S amplified PCR + sequencing (not the most efficient). Else, the most used is the Gram coloration and then the culture. A response can be given in 24h/48h (or longer: 5 days for some bacteria and 3 weeks for mycobacteria).<br>
 +
There are also cultures identified by MALDI TOF (2h of preparation on ion exchanging resin + growing time of the bacteria). Specificity is excellent and the sensitivity is good. There is also the possibility of identification by biochemical method (enzyme, (quite rare nowadays).
 +
</p>
 +
 +
 +
<p><b><i>If not mentioned previously: Do you have an antibiogram? How long does it take to make a diagnosis?</i></b></p>
 +
<p>We use mainly phenotypic antimicrobial susceptibility tests (not genetic in general, more for virology) which need about 48h to 72h.<br>
 +
Else by PCR (Staphylococcus aureus by PCR → Research of methicillin resistance).<br>
 +
Nothing replace a antimicrobial susceptibility test for now, result in 48h - 72h (including the culture time).
 +
</p>
 +
<br>
 +
 +
<p><b><i>System overview. Do you think at first sight that it meets the security criteria of the service? Other remarks?</i></b></p>
 +
<p>“Are you doing bacterial culture after the transformation or not ?” - “Nope”<br>
 +
Giving a result in less than 10h is interesting, it is less than a bacterial culture so the delay is performant. But the detection PCR need only 2h to give a result… We have to be careful to only extract the bacterial DNA. He thinks the project is interesting. He is not passionate by the identification side but by the therapy side.
 +
</p>
 +
 +
<p><b><i>How are biological waste managed in your service? Is the waste management of our kit manageable in your service? In the hospital?</i></b></p>
 +
<p>They already manage more dangerous waste in the waste treatment process. All the waste is incinerated. Our waste represent nothing problematic for the service.<br>
 +
Example :  The universitary hospital center is equipped to manage all the waste from all the infectious and assimilated curing activities. The management of our waste therefore represent no problem for a hospital.
 +
</p><br>
 +
 +
<p><b><i>Did you have any bioethics training during your studies or after your studies?</i></b></p>
 +
<p>A bit but not much. That is more about practice during the job exercise : interactions with bioethical institutions, ethical seminars in medicine with people having ethical formations way more thorough. And of course there is the knowledge of bioethical laws.<br>
 +
He thinks there is not the time to do more during the medicine study program. Anyway doctors do ethics every day (tell or not a disturbing truth, to who let the access to this patient record…). Also in research, every day there are ethics, in the realization of experiences, surveys...
 +
</p><br>
 +
 +
<p><b><i>If no, do you think that bioethics training is missing in your learning?</i></b></p>
 +
<p>No. In reality they do bioethics all the time. Consents, palliative care, accompanying someone's death, bioethical laws: they face ethics every day. The training is clearly not empty on the subject, whether in class or in practice.

<p>A wound, I have hammer legs (claw feet/toes) (deformation of the toe), the toes do not touch the ground and in the shoe it made a light bulb. One evening a piece left and it made a sore and the infection came. It has been 13 years since I have the infection. 6 months ago it was two feet.</p>
  
 
<p><b><i>Were you treated early on right foot?</i></b></p>
 
<p><b><i>Were you treated early on right foot?</i></b></p>
 
+
<p>Yes, I had a lot of surgery, then it did a perforating ache (dermatological lesion) and they treated me with antibiotics. The last time I had surgery, I had 7 months of treatement with antibiotics, and there was no result.</p>
  
  
 
<p><b><i>Do you know which antibiotic you have been treated with?</i></b></p>
 
<p><b><i>Do you know which antibiotic you have been treated with?</i></b></p>

<p><b><i>When did the antibiotics stop working?</i></b></p>

<p><b><i>Do you know if it was always the same, or it was an antibiotic cocktail?</i></b></p>
 
+
<p>No, at home I took the antibiotics but one day my face was gray, and meanwhile I went for X-ray in Meylan and a lady said to me "if you want I know someone who has been treated with the phages, do you want to see him?“<br>
 +
I said there was no problem because the doctor wanted to cut my legs. So I went to see the person being treated by the phages, and he was able to walk. Then I contacted a doctor from Nîmes, Mr. Riche. I took an appointment at Nîmes to see him. The doctor knew of what bacteria I was infected so he told me "you have to take such phages and put them on the wound.
 +
</p>
  
 
<p><b><i>Was it a liquid to put?</i></b></p>
 
<p><b><i>Was it a liquid to put?</i></b></p>
 +
<p>Yes, and it was not enough, I had to have surgery. I asked my doctor at the CHU de Grenoble (University Hospital of Grenoble) whether during the operation he could put the phages on me but he refused. So Mr. Riche advised me someone in Clermont-Ferrand who operates with phages. So I took appointment with the doctor from Clermont-Ferrand and he operated on me with the phages. Then I continued to put phages on the wound and I drank too.
 +
</p>
 +
 +
<p><b><i>Is it  really better? Do you feel it?</i></b></p>
 +
<p>Yes</p>
 +
 +
<p><b><i>Did you notice side effects because of the treatment with phages?
 +
</i></b></p>
 +
<p>No and I saw the person who was treated with the phages and he was fine.</p>
 +
 +
<p><b><i>How long did it need until you saw an evolution after you started to use phages?
 +
</i></b></p>
 +
<p>6 months, even less. In addition to taking phages there is a diet to do, and take blood tests (18ml). The blood tests must be re-injected intramuscularly but the nurses do not have the right to do it so it was my wife who did it.
 +
</p>
 +
 +
<p><b><i>And you were not afraid at all even after that? </i></b></p>
 +
<p>No because otherwise I was cut off the leg
 +
</p>
 +
 +
<p><b><i>Yes it is true that you prefer to try rather than lose your leg</i></b></p>
 +
<p>Yes. There is a blood test today and then 4 days later then 8 days later and there are 8 sessions to be done.
 +
</p>
 +
 +
<p><b><i>Do you put the phages everyday?</i></b></p>
 +
<p>Yes since 1 year and the wound is almost healed. But with my job (farmer) I had to go back to work, so they plastered me with a plate underneath, so  I could work.But the wound remained and the infection appeared on the left foot too.
 +
</p>
 +
 +
<p><b><i>Is it the same wounds on both feet?
 +
</i></b></p>
 +
<p>Yes, but the left is because of the shoes. I have a foot sensitivity disorder so it rubbed, it made a sore so the nurses tried to treat me but the problem is that toes have broken. I asked to operate with phages but they refused and suddenly I asked if after the nurses could put me phages on my toes and they told me no problem.
 +
</p>
 +
 +
<p><b><i>Who told you about Mr. Riche?
 +
</i></b></p>
 +
<p>I did it myself, I inquired. Mr. Riche advised me to put more on my wounds of hydrogen peroxide and we saw that after a day the wound became pink when before it was black.
 +
</p>
 +
 +
<p><b><i>Do You know what bacteria infected You?
 +
</i></b></p>
 +
<p><i>Staphylococcus</i> and en another. So, Mr. Riches, seeing that said to me that such phages I needed.
 +
</p>
 +
 +
<p><b><i>Do you know if it is a phage cocktail or a phage in particular?
 +
</i></b></p>
 +
<p>One for <i>Staphylococcus</i> and one for the other bacterium.
 +
</p>
 +
 +
<p><b><i>Phage therapy therapy is more developed in Eastern countries than in France, right?
 +
</i></b></p>
 +
<p>Yes phages come from Ukraine. It is Monsieur Riche who makes them come. But now when it arrives at the customs, they break the flacons. So now it passes by another name.
 +
</p>
 +
 +
<p><b><i>With the research you have done, have you found other doctors who practice phage therapy ?</i></b></p>
 +
<p>No, just Monsieur Riche and the doctor from CLermont-Ferrand. The other day I saw him and said, "See, I still have my leg”
 +
</p>
 +
 +
<p><b><i>It proves that it works well.</i></b></p>
 +
<p>Yes, and Monsieur Riche has written a book, it can be found on the internet and he has made ointment, it is a healing ointment that I put on my wounds.
 +
</p>
 +
 +
<p><b><i>You think we can reach Mr. Riche for more information?
 +
</i></b></p>
 +
<p>Yes Yes ! It will make him happy
 +
</p>
 +
 +
<p><b><i>How much does a treatment cost?
 +
</i></b></p>
 +
<p>It costs nothing, it is flasks, it costs 45 euros with all inclusive for 6 bottles!
 +
</p>
 +
 +
<p><b><i>Do you still take AB anyway?
 +
</i></b></p>
 +
<p>Yes</p>
 +
 +
 +
<p><b><i>And once you've taken phage treatment, do you feel really better?
 +
</i></b></p>
 +
<p>Yes, not the first shot but afterwards as I was in shape. And he cared for cancer too, from a woman who lives in Meylan. Thus she was saved.</p>
 +
 +
<p><b><i>How much time do you still have?
 +
</i></b></p>
 +
<p>It is necessary to wait until the wound is completely closed</p>
 +
 +
 +
<p><b><i>And how long have you been treating yourself to phages?
 +
</i></b></p>
 +
<p>5 years</p>
 +
 +
<p><b><i>Did the treatment hurt you?
 +
</i></b></p>
 +
<p>No, we feel nothing at all, it is just put on wounds and swallow (morning fasting) and also I pay attention to what I eat, wholemeal bread, whole rice no potato no red meat, no coffee, no sugar .. it is for healing especially

<p>&quot;Science without conscience is only ruin of the soul&quot; said F. Rabelais. Therefore, what consciousness are we talking about ? That of the scientist alone, that of his peers, or even the collective consciousness of a society, of the whole of humanity? For a long time, science thought itself capable of inventing, evaluating and understanding the stakes of its discoveries by its protagonists alone, but it is clear that this vision no longer has any relevance today. We have entered a new era, that of post-modernity; it is characterized by a questioning of science
 +
and its basic axioms, but also, a doubt as to the ability of its actors to consider all the
 +
dimensions of their discipline, as well as their legitimacy to choose in the name of the
 +
community. The stakes of science and technology are unprecedented, these two disciplines
 +
are at the heart of our lives and our future. Thus, they must be thought of and questioned, that
 +
in view of their potential consequences. The technique, but also the science that gives it body
 +
must be the concern of all. </p>

ACTORS AND PARTNERSHIPS

It is impossible to use bacteriophages and to develop a detection device if we do not know what are the needs and the constraints in hospitals and in medical analysis laboratory. So we need to discuss our project with physicians, specialists and even with the whole population. We also developed partnerships with local research laboratories and companies, to borrow equipment, recover bacteria and bacteriophages, and, most important, ask them for advice.


GROUND FLOOR: We established partnerships with local companies like Biomérieux and local laboratories like TIMC in order to benefit from their advice/expertise and we had the opportunity to get some of their biological material. Our engineers and researcher partners gave us a lot of recommendations all along the summer and helped us to get an external point of view on our project.


FIRST FLOOR: We visited a medical analysis laboratory and we met the laboratory manager. We discussed with him about the detection system used in his laboratory and about the advantages and limits of our system, if it was used in this kind of laboratory.


SECOND FLOOR: We met with doctors and patients who talked with us about bacteriophages and antibiotic resistance. We discussed with them to know if our detection system could be used in hospitals and what modification we should make in order to improve it. You can have a look at them on the third floor (see our schematic below).


THIRD FLOOR: All the societies must be implicated in our project. But it is essential for us to be aware of what people know about phage therapy and antimicrobial resistance. It is important to evaluate people's knowledge and then produce an appropriate outreach.



CLICK ON THE PEOPLE YOU WANT TO HEAR FROM ! Everybody has something interesting to share with you.




GROUND FLOOR:




Learn how partnerships had influenced our project !


BIOMERIEUX



According to their advice we have:
- used a lysis buffer as an efficient positive control
- planned to add a cover to protect the contents of the tubes
- placed a ball bearing in the axis of the pipette
- understand that hybridization will happen even without mutations, rendering false positives. A possible idea to fix this problem is to do as for the resistance probe design on Staphylococcus aureus: it is necessary to find an enzyme that cuts at the place of the mutation (butt or cohesive) and a plasmid that is cut in the same place. In this case even if there is hybridization with the two ends cut it does not reform the plasmid, so it is not transformed if there is no mutation.
But the plasmid must be in very large excess to decrease the effect of competition and it is unlikely to find an enzyme that cuts at the level of mutation. This problem might be solved by using CrisPr-Cas9 system.


TIMC


Béatrice advised us to make dilutions of the positive control for the freeze-drying of bacteria rather than comparing with the frozen equivalent each time. She also advised us to compare the processing efficiency after freeze-drying with the conventional laboratory freezing method (number of colonies similar to a given dilution).


Les midis MINATEC


Cécile Breton's conference on phage therapy, antibiotic resistance, hyper-efficiency and specificity of phages led us to choose the subject of our project.


AVALUN


Avalun offered us SMD camera fluorescence detection and advised us to work with STmicroelectronics.









FIRST FLOOR:




INTERVIEW WITH PIERRE-ALAIN FALCONNET
Medical Analysis Laboratory Manager
ORIADE NOVIALE



We presented our system to Pierre Alain Falconnet to see if it could work in the context of a medical analysis laboratory. The system seems totally adapted to the laboratory use. According to him, the operating principles are good. It is still necessary to make specificity and sensitivity tests and to know the processing time of a sample.
The most important is to have an accreditation (COFRAC, CEIVD) because without this, the analysis laboratories will probably not want to have the system.
If the use of phages is regulated by a standard P2 and not P3 or P4, he could even use the machine in his own laboratory.
He offered to help us by giving us test samples.


Read the interview with Pierre-Alain Falconnet

Did you know iGEM before I told you about it?

No


Do you often encounter antibiotic resistant bacteria in your department ?

"YES, all the time, and we sometimes even encounter bacteria resistant to all antibiotics and this occurs more and more."


Do cases of Pseudomonas aeruginosa infections represent a large percentage of infections ?

This does not represent a large percentage of infections in the case of city medicine. In hospitals, there are many more, but it is also not the most prevalent infection.
It may be responsible for cystic fibrosis in immunosuppressed patients, urinary tract infections, respiratory infections, intubated infections (clinical care).

Do you know Phage Therapy? If so, what do you think?

He heard about it "Antibiotic therapy we see these limits [..] We see resistances appearing, we see that in some cases doctors can not bring solutions of treatment. The new antibiotic molecules do not come out every day and they do not bring much new stuff and it is very toxic. " There is no new class of antibiotics. He had a scientific monitoring about the bacteriophages, “maybe tomorrow we will have phagograms” he said. A former colleague of him is working on aromatograms.

Is it possible to manipulate phages in your service (ours + in general), are there specific safety rules?

He does not know enough about the virulence of the phage, and its potential to be harmful. The hospital has a P3 laboratory (tuberculosis research) P4 in virology. There are some private labs with P3 and P4 (biomnis in Lyon).
If phage use follows P2 safety rules then no problem.

Is it possible to handle modified E.coli in your department (problem of horizontal gene transfer)?

Yes it is possible, we just need to apply adequate security rules for staff.



What are the diagnostic tools available in your service to detect pathogenic bacteria (and for Pseudomonas especially) ? How much time is needed to provide a diagnostic ? With which reliability (specificity and sensibility) ? What is the prices of those devices (price of the machine and price of diagnostic per patient) ? According to you, what are the qualities of a good diagnostic device adapted to the hospitals ?

- The Bactec: hypersensitive, relatively specific
- Real-time PCR: more sensitive than anything previously done, more specific than before : now we even see vibrios that we did not see
- Antibiogram. Can quickly make nonsense, problems of resistance.
In this laboratory, there is no system using GMOs.

In your laboratory, do you realize the accreditations imposed by the COFRAC (French Accreditation Committee)?

CEIVD (european conformity in vitro diagnostic medical device) reagent labeling: reagent studies -> repeatability, reproducibility, sensitivity, specificity, accuracy, detection limits, limit of quantification, analytical interferences .... We do not need to repeat the tests.
"You come to see a lab like us, you present a reagent that is not marked CEIVD, many will say no, we are not interested."



System overview. Do you think at first sight that it meets the security criteria of the service? Other remarks?

The system is fine, there are no special remarks.
Biomérieux, buys startups that have developed systems: time-saving research, turnkey technologies at the laboratory.
You have to validate the techniques before using them. To make an antibiogram in the day would of course be ideal.
Avalun: capillary reader. Test work is done in a laboratory.
The machine can be tested without any problems in the laboratory if accreditation is obtained.
Comex, and the general assembly of the laboratory, ethically accept whether the new technology can be purchased.
Image problem with the use of GMOs "We can help by donating strains"

How are biological waste managed in your service? Is the waste management of our kit manageable in your service? In the hospital?

Use of American bins for each waste from each room. Subcontracting to Veolia who comes to collect the bins.
So no worries for our waste

INTERVIEW WITH PR. MAX MAURIN
Head of Bacteriology Department
La Tronche Hospital



Dr. Maurin thinks that our system is very interesting and answers well the given problem. However, some biological risks have to be taken into account such as the dissemination of the system components. If these aspects are well evaluated and handled, the system is very promising. Yet, Dr. Morin thinks that it will be very difficult to play on the sensitivity and the specificity of our system to compete with today’s methods in molecular biology. Among all the different specificities of our system, it is mostly the bacteriophages selection that caught his attention the most.

At last, Dr. Morin thinks that physicians do not have enough ethical formations and are not aware enough of new bioethical laws.


Read the interview with Pr. Max Maurin

Can you present yourself ? Is it okay to take a picture of you ?

Yes. Originally a medical doctor, I chose to pursue an internship in medical biology with a specialization in microbiology. I also did a Master and a thesis in a university hospital (double degree)? After my internship, I was an assistant in the university hospital then I became master of conferences and practitioner at the hospital. Nowadays, I am in charge of the bacteriology department in the Grenoble UHC.


Did you know iGEM before I told you about it?

Not in the details but I have already heard about it thanks to my colleagues (some of them even helped the previous Grenoble iGEM team).


Do you often encounter antibiotic-resistant bacteria in your department?

This is a current issue. There are a lot of new resistant bacteria. Most of my activities are centered on the subject. It includes antibiotic resistance characterization and antibiotic efficiency prognosis.
“It is not a new issue.”
In the hospital, antibiotics are used a lot and there is an emergence of poly resistant bacteria strains. The industry did not succeed in developing antibiotics to remedy to the resistance issues. The bacteria won.
“There are many strains that became resistant to most of the antibiotics” so “the therapeutic possibilities decreased little by little”.
“It is a real issue for public health” but we know how to treat most of the cases though. “There is an emergence of of therapeutic dead-ends in the hospital, that we we did not see since long time ago. People have infections with zero treatment possible to cure them, that is rare.”
“Each year, new resistances emerge and we see their prevalence increasing. That is a reality.”

Do cases of Pseudomonas aeruginosa infections represent a large percentage of infections?

It is a significant pathogen, even though initially not very virulent. In the hospitals it is an issue for weakened people (immunosuppressed people, or in extended care). It is an hospital pathogen. “This strain has a lot of facilities to acquire new resistances”.

Do you know phage therapy? If so, what do you think?

There are difficulties to find the good bacteriophages, the not pathogenic ones.
Ethical problems persist. Resistance problems still persist. Bacteriophages are an interesting concept but should be used as a last resort.
There are also new alternatives like anti-virulence drugs to prevent the virulence of bacteria but not their growth. “They are less selective molecules that act on virulence factors without killing them”. It can be used as a treatment by itself or to associate with antibiotics.
Some drugs to boost immune defenses also exist.

Is it possible to manipulate phages in your service (ours and generally speaking), are there specific safety rules?

Viruses were used in the past for typing in molecular biology labs in hospitals.
However many regulations are necessary for the drugs and even more for “living” drugs. There is an additional constraint not to infect the patients and the medical staff. There is a fear that viruses could transmit the resistances (horizontal transfer).

Is it possible to handle modified E.Coli in your department (problem of horizontal gene transfer)?

Maybe special authorisations are needed since they are GMOs. At least a declaration is mandatory.

What are the diagnostic tools available in your service to detect pathogenic bacteria (and for Pseudomonas especially) ? How much time is needed to provide a diagnostic ? With which reliability (specificity and sensibility) ? What is the prices of those devices (price of the machine and price of diagnostic per patient) ? According to you, what are the qualities of a good diagnostic device adapted to the hospitals ?

2 main classes of tools are available in my service:
1) Isolation with bacterial culture which allows the identification of bacteria and the characterization (antibiotics activity and efficacy against the strain.)
If it is too complex or if we need to be faster :
2) All that includes Biochemical Methods: PCR (PCR in real time -qPCR-). Research for a pathogen.
About the sensibility, PCR is the less risky technic regarding to the sample contamination (between them). It is the most reliable technic and it is very fast (1 to 2 hours). Sequencing is a bit long because it has to be sent out of the hospital so it requires about 3 days or more.
Example : Isolation + antimicrobial susceptibility testing for Pseudomonas and resistance origin identification. If we want more details (carbapenemase type…) the most adapted will be qPCR. Of course ,the method used must be adapted according to the case complexity and the time available.
He estimates that nowadays in the university hospital center the repartition of the methods used is about:
- 90% of antimicrobial susceptibility testing and phenotypic methods
- 10% of Molecular Biology

If not mentioned previously: Do you have an antibiogram? How long does it take to make a diagnosis?

Isolation and antimicrobial susceptibility testing represent 90% of analyses. They are relatively reliable. If the phenotype does not allow to get all the information needed, we switch to molecular biology methods.
So molecular biology in real time represents 10% of analyses. In particular cases there is not any tool available, if new resistance mechanisms appear, we can obtain false positives due to contamination. Still the reliability of real time molecular biology remains good and adapted to the complexity and the need to act quickly.


System overview. Do you think at first sight that it meets the security criteria of the service? Other remarks?

The two main risks for the system are :
1- Biological risk (for the medical staff), pathogen classification (here P2 but not too serious, in particular for healthy people, so there is no epidemic risk)
2- GMO risk, we have to evaluate the diffusion and dissemination risks for us and find how to treat the contaminated waste.

How are biological waste managed in your service? Is the waste management of our kit manageable in your service? In the hospital?

We use Citybac® DASRI to throw the infection-risk waste and then everything is incinerated. Water is treated before being dumped.


Did you have any bioethics training during your studies or after your studies?

No, he learned on the job. He never got any specific formation on the subject. Some colleagues got teachings in other formations.

If no, do you think that bioethics training is missing in your learning?

YES, the regulation is really constraining in medicine, a formation on bioethical laws should be dispensed at the beginning. Doctors are each day more led to have ethical reflexions but can definitely do better. Some people have the knowledge but the majority is not up to date on the regulation and recent laws.




INTERVIEW WITH PR. OLIVIER EPAULARD
Head of the Infectious and Tropical Diseases Department
La Tronche Hospital



Pr. Epaulard thinks that the project is very interesting. He is not overly passionate about the identification aspect but rather by the therapy aspect of the project. The diagnostic tools he uses have already very good specificity and sensitivity. It is going to be hard to compete with them. He verified many aspects of the biology in the system and was pleased with our answers.

Pr. Epaulard thinks that one can learn about bioethics through practice. Therefore, there is no need for more theoretical courses on ethics in a physician formation.


Read the interview with Pr. Olivier Epaulard

Did you know about iGEM before I told you about it?

No.

Do you often encounter antibiotic resistant bacteria in your department ?

Daily. Every day, all the time. They are the result of antibiotics misuse (about 90% of the cases). He estimates that half of antibiotic treatments are wrongly prescribed. According to a study, half of the doctors antibiotic prescriptions are useless. Antibiotic resistant bacteria are enterobacteria in majority. The resistances are due to penicillinase (and other beta-lactamase / enzymes). The number of infections with resistance keeps increasing.
Although rare, there are cases of infection for which no treatment is possible (no antibiotic is able to kill the bacteria which resistant to everything). Some countries like India, Greece, Turkey and some african countries are at a critical stage. They are not anymore trying to manage the use of antibiotics but they are looking for methods to treat patients infected by bacteria resistant to nearly all the antibiotics.
Resistances appear on strains that were sensible to everything in the past. Antibiotics come from mushrooms (penicillium, ...). They are very old molecules, and that explains why bacteria can have facilities to become resistant. To reverse the process of antibiotics abusive utilisation is very complicated and hard to impulse (in particular concerning the education of the population and of practitioners). → Analogy with the global warming: The majority knows but it requires strong behaviour changes not realized. Is it too late ? Resistance of Gram bacilli - like Pseudomonas - increases.
Nowadays, more and more people are immunosuppressed (But they would be dead before without treatment. Often, the immunosuppression comes from a heavy treatment) or go through treatments exposing them to bacteria for a long or excessive duration. For example immunosuppression for grafts or surgeries are more and more risky since they are open doors to infections. On another hand, exposition to bacteria is more and more common because of the treatments lengthening.

Do cases of Pseudomonas aeruginosa infections represent a large percentage of infections?

Concerning common infections, we meet rarely Pseudomonas aeruginosa in general but it is present in the hospital infections in the operating rooms for patients that have a catheter in a vein, a contact with material, or a urinary infection.

Do you know Phage Therapy ? If so, what do you think ?

Yes. He can not have a precise idea. On paper, he is enthousiast to this idea. Moreover phages seem to be easy to produce. While antibiotics can lead to intestinal flora diseases during their ingestion, phages can avoid that. In the case of chronic infections on prosthesis, to change the material is the only way to cure the infection… The phage therapy could also be a way to clean the medical material.
But he feels like it has been 15 years that he is hearing about phages and that nothing happens. He thinks that there are maybe other problems in the utilization of phages than
just the patent problematic, finally a not so important matter according to him. Indeed, in France modified viruses have been patented, a modified bacterium could be patented, so patenting a living organism is possible,... Hence, why not the phages ? One advantage of the phage is their permanent efficacy on the bacteria. Indeed antibiotics are effective only on growing bacteria. However it is the case for infections such as pneumonia and urinary infections but not long ones like bones infection for which the phage utilization would be very interesting.
Russia and Georgia tell that they produce phages in GMP (good manufacturing practice) but with which purity ? Which vivacity ?
Interesting book: “La Phagothérapie - Des virus pour combattre les infections “ Alain Dublanchet

Is it possible to manipulate phages in your service (ours + in general), are there specific safety rules?

Yes !! No particular problem.

Is it possible to handle modified E.Coli in your department (problem of horizontal gene transfer)?

Not any problem, everybody manipulate bacteria with plasmid containing resistance/selection genes. The evacuation system is ok and allow to avoid any crossing and to spread bacteria in the environment.


What are the diagnostic tools available in your service to detect pathogenic bacteria (and for Pseudomonas especially) ? How much time is needed to provide a diagnostic ? With which reliability (specificity and sensibility) ? What is the prices of those devices (price of the machine and price of diagnostic per patient) ? According to you, what are the qualities of a good diagnostic device adapted to the hospitals ?

The tools available in my service are multiplex PCR (not very efficient), targeted PCR, 16S amplified PCR + sequencing (not the most efficient). Else, the most used is the Gram coloration and then the culture. A response can be given in 24h/48h (or longer: 5 days for some bacteria and 3 weeks for mycobacteria).
There are also cultures identified by MALDI TOF (2h of preparation on ion exchanging resin + growing time of the bacteria). Specificity is excellent and the sensitivity is good. There is also the possibility of identification by biochemical method (enzyme, (quite rare nowadays).

If not mentioned previously: Do you have an antibiogram? How long does it take to make a diagnosis?

We use mainly phenotypic antimicrobial susceptibility tests (not genetic in general, more for virology) which need about 48h to 72h.
Else by PCR (Staphylococcus aureus by PCR → Research of methicillin resistance).
Nothing replace a antimicrobial susceptibility test for now, result in 48h - 72h (including the culture time).


System overview. Do you think at first sight that it meets the security criteria of the service? Other remarks?

“Are you doing bacterial culture after the transformation or not ?” - “Nope”
Giving a result in less than 10h is interesting, it is less than a bacterial culture so the delay is performant. But the detection PCR need only 2h to give a result… We have to be careful to only extract the bacterial DNA. He thinks the project is interesting. He is not passionate by the identification side but by the therapy side.

How are biological waste managed in your service? Is the waste management of our kit manageable in your service? In the hospital?

They already manage more dangerous waste in the waste treatment process. All the waste is incinerated. Our waste represent nothing problematic for the service.
Example : The universitary hospital center is equipped to manage all the waste from all the infectious and assimilated curing activities. The management of our waste therefore represent no problem for a hospital.


Did you have any bioethics training during your studies or after your studies?

A bit but not much. That is more about practice during the job exercise : interactions with bioethical institutions, ethical seminars in medicine with people having ethical formations way more thorough. And of course there is the knowledge of bioethical laws.
He thinks there is not the time to do more during the medicine study program. Anyway doctors do ethics every day (tell or not a disturbing truth, to who let the access to this patient record…). Also in research, every day there are ethics, in the realization of experiences, surveys...


If no, do you think that bioethics training is missing in your learning?

No. In reality they do bioethics all the time. Consents, palliative care, accompanying someone's death, bioethical laws: they face ethics every day. The training is clearly not empty on the subject, whether in class or in practice.




INTERVIEW WITH H.G, PATIENT TREATED WITH PHAGE THERAPY



We do not put the image and the name of H.G because phage therapy is not allowed in France

After getting infected feet wounds, H.G was treated with antibiotics but the infection was not cured. No antibiotic worked and the infection spread. The only way to treat this patient was to amputate the two legs. H.G had heard about phage therapy and contacted a doctor specialized on the subject. He chose to try phage therapy to cure his wounds. Bacteriophages were applied for a year on the wounds and he is now almost cured.

On the pictures, you can see the state of his left foot before and after the phage therapy.

WARNING: this includes images some readers may find disturbing (OPEN WOUNDS)

Necrotic wound (black tissues)before phage treatment

Healing wound (pink tissues) after phage treatment

Read the interview with H.G

Where did the infection come from?

A wound, I have hammer legs (claw feet/toes) (deformation of the toe), the toes do not touch the ground and in the shoe it made a light bulb. One evening a piece left and it made a sore and the infection came. It has been 13 years since I have the infection. 6 months ago it was two feet.

Were you treated early on right foot?

Yes, I had a lot of surgery, then it did a perforating ache (dermatological lesion) and they treated me with antibiotics. The last time I had surgery, I had 7 months of treatement with antibiotics, and there was no result.

Do you know which antibiotic you have been treated with?

No, but at the last operation my doctor told me that the last option was to cut the leg.

When did the antibiotics stop working?

It has been 3 years since antibiotics are no longer effective.

Do you know if it was always the same, or it was an antibiotic cocktail?

No, at home I took the antibiotics but one day my face was gray, and meanwhile I went for X-ray in Meylan and a lady said to me "if you want I know someone who has been treated with the phages, do you want to see him?“
I said there was no problem because the doctor wanted to cut my legs. So I went to see the person being treated by the phages, and he was able to walk. Then I contacted a doctor from Nîmes, Mr. Riche. I took an appointment at Nîmes to see him. The doctor knew of what bacteria I was infected so he told me "you have to take such phages and put them on the wound.

Was it a liquid to put?

Yes, and it was not enough, I had to have surgery. I asked my doctor at the CHU de Grenoble (University Hospital of Grenoble) whether during the operation he could put the phages on me but he refused. So Mr. Riche advised me someone in Clermont-Ferrand who operates with phages. So I took appointment with the doctor from Clermont-Ferrand and he operated on me with the phages. Then I continued to put phages on the wound and I drank too.

Is it really better? Do you feel it?

Yes

Did you notice side effects because of the treatment with phages?

No and I saw the person who was treated with the phages and he was fine.

How long did it need until you saw an evolution after you started to use phages?

6 months, even less. In addition to taking phages there is a diet to do, and take blood tests (18ml). The blood tests must be re-injected intramuscularly but the nurses do not have the right to do it so it was my wife who did it.

And you were not afraid at all even after that?

No because otherwise I was cut off the leg

Yes it is true that you prefer to try rather than lose your leg

Yes. There is a blood test today and then 4 days later then 8 days later and there are 8 sessions to be done.

Do you put the phages everyday?

Yes since 1 year and the wound is almost healed. But with my job (farmer) I had to go back to work, so they plastered me with a plate underneath, so I could work.But the wound remained and the infection appeared on the left foot too.

Is it the same wounds on both feet?

Yes, but the left is because of the shoes. I have a foot sensitivity disorder so it rubbed, it made a sore so the nurses tried to treat me but the problem is that toes have broken. I asked to operate with phages but they refused and suddenly I asked if after the nurses could put me phages on my toes and they told me no problem.

Who told you about Mr. Riche?

I did it myself, I inquired. Mr. Riche advised me to put more on my wounds of hydrogen peroxide and we saw that after a day the wound became pink when before it was black.

Do You know what bacteria infected You?

Staphylococcus and en another. So, Mr. Riches, seeing that said to me that such phages I needed.

Do you know if it is a phage cocktail or a phage in particular?

One for Staphylococcus and one for the other bacterium.

Phage therapy therapy is more developed in Eastern countries than in France, right?

Yes phages come from Ukraine. It is Monsieur Riche who makes them come. But now when it arrives at the customs, they break the flacons. So now it passes by another name.

With the research you have done, have you found other doctors who practice phage therapy ?

No, just Monsieur Riche and the doctor from CLermont-Ferrand. The other day I saw him and said, "See, I still have my leg”

It proves that it works well.

Yes, and Monsieur Riche has written a book, it can be found on the internet and he has made ointment, it is a healing ointment that I put on my wounds.

You think we can reach Mr. Riche for more information?

Yes Yes ! It will make him happy

How much does a treatment cost?

It costs nothing, it is flasks, it costs 45 euros with all inclusive for 6 bottles!

Do you still take AB anyway?

Yes

And once you've taken phage treatment, do you feel really better?

Yes, not the first shot but afterwards as I was in shape. And he cared for cancer too, from a woman who lives in Meylan. Thus she was saved.

How much time do you still have?

It is necessary to wait until the wound is completely closed

And how long have you been treating yourself to phages?

5 years

Did the treatment hurt you?

No, we feel nothing at all, it is just put on wounds and swallow (morning fasting) and also I pay attention to what I eat, wholemeal bread, whole rice no potato no red meat, no coffee, no sugar .. it is for healing especially

Our Survey about antimicrobial resistance, phage therapy and iGEM


"Science without conscience is only ruin of the soul" said F. Rabelais. Therefore, what consciousness are we talking about ? That of the scientist alone, that of his peers, or even the collective consciousness of a society, of the whole of humanity? For a long time, science thought itself capable of inventing, evaluating and understanding the stakes of its discoveries by its protagonists alone, but it is clear that this vision no longer has any relevance today. We have entered a new era, that of post-modernity; it is characterized by a questioning of science and its basic axioms, but also, a doubt as to the ability of its actors to consider all the dimensions of their discipline, as well as their legitimacy to choose in the name of the community. The stakes of science and technology are unprecedented, these two disciplines are at the heart of our lives and our future. Thus, they must be thought of and questioned, that in view of their potential consequences. The technique, but also the science that gives it body must be the concern of all.
