Gold Integrated Human Practices

Our integrated human practices are the result of each and every single human practices activity that we carried out throughout the iGEM season. We truly believe our work, in every section of our project, including wet lab, has significantly changed towards the implementation of our relevant communities feedback. Since the first day we engaged with beekeepers, our project has been shaping and improving towards an effective, responsible, safe and ethical work.


After the video call we had with Maria Mercedes Roca, Ph.D, where emphasis was placed on the three pillars of the UN for sustainable development, we saw the importance of these three areas and decided to exploit them in our integrated human practices: the economic, social and environmental area of our project, as well as a section showing how the design and execution of it has been, molded thanks to our silver human practices.



Project Basis

The foundation of the project was evolving, improving and solidifying thanks to the interactions we experienced in our human practices. There were fundamental changes such as the production chassis of the peptides and the application method of the product, as well as recommendations for the experimental plan and insights about the risk factors we should consider.

Excretion of antimicrobial peptides in Pichia pastoris for Paenibacillus larvae and Melissococcus plutonius inhibition. The initial plan was to apply genetically modified yeasts engineered to excrete AMP’s and surfactin in a solution with hexane extract of the plant A. satureioides; surfactin has a synergistic effect with the hexane extract. This solution would be applied to the bee bread we knew larvae ingested in their diet.


Learned obstacles regarding the method:

  1. Presence of genetically modified yeats would complicate the exportation process of honey to the European Union increasing the risks of having the product rejected.
  2. The hexane extract of A.satureioides is oxidized by exposure to air; therefore, it may lose its efficiency.
  3. An overdose of yeasts would cause fermentation of the honey and an alteration in the microbiota of the bees which could be counterproductive since this would cause diseases such as Nosema and American foulbrood to arrive.


Production of antimicrobial peptides in Escherichia coli for Paenibacillus larvae and Melissococcus plutonius inhibition. The second plan consisted in applying the purified antimicrobial peptides, after their production in E. coli BL21 (DE3), in the bee bread we knew larvae ingested in their diet.


Learned obstacles regarding the method:

  1. Bee bread is mainly stored in the hive so there is little chance that the peptides reach the larva.


The third plan consisted in applying the purified peptides sprinkled as a liquid solution or as a powder on the hives.

Learned obstacles regarding the method:

  1. When the product is found scattered in the hive, it can be easily affected by external factors such as air or other insects.

We were able to arrive at the final application method with the recommendation of MVZ Ernesto Tanús who considered that the most suitable way to apply our product would be through the liquid food beekeepers provide to the hives and that nurse bees ingest to feed the larvae subsequently.


Experimentation plan

We integrated three aspects discussed during our interviews within the future experimentation plan of the project:

  1. Add an innocuous color dye to the nanospheres to make the track in the bee system and ensure that the product reaches the larvae. This topic was discussed during the meeting with MVZ Ernesto Tanús Sánchez, MVZ Adolfo Arroyo, and Eng. José Luis González Miranda.
  2. Test the research on the pure Italian Apis mellifera spp. ligustica, as it is the most widespread in the world. This information was considered thanks to the video call with FAI presidential staff member Lorenzo Della Morte.
  3. Extract the hypopharyngeal glands of the nurse bees after they consume the liquid food where nanospheres were added in order to determine if there is the presence of AMP's. Consideration taken from the conversation with Ph.D. David de Jong.

Important considerations for the project

MVZ Ernesto Tanús considered it was essential to take into consideration the factor of the microbiota of the bee, regarding the fact that there would be AMP's supplied that can alter the natural microbiota. Regarding this same subject, Ph.D. David De Jong considered that our product works like the antibiotics humans use; there is the negative part that the intestinal flora will be affected, but this is in search for a greater good, attacking pathogens. The experimentation is necessary in order to be able to know what would happen with the microbiota of the bee and what consequences this situation could bring.


Another of the considerations of Ph.D. David De Jong, was the analysis on how when you give certain substance to an animal, there is a proclivity for it to produce less of this substance; risk addressed in the bioethical essay and mentioned in the legal plan.








Environmental


The importance of the environment for the subsistence of life on earth is unquestionable. The magnitude of its value is represented by the human right to a healthy environment, a prerogative that protects the environment as a fundamental legal right and expresses the relevance of this to have a dignified life. This human right constitutes a guarantee for the realization and validity of the rest, since human being are in an indissoluble relationship with its environment and nature1. For this reason, achieving sustainable development would ensure the quality of present and future life. In this sense, the dignity, autonomy, and sanctity of the person depend on the health of the planet, its resources, and species.


Food Security is a central topic in the global agenda. The Food and Agriculture Organization (FAO) estimates that by the year 2050, world population will exceed 9,000 million, of which 150 million will dwell in Mexico. This should increase agricultural production by 60% in the country by that year 2.


Beekeeping is a fundamental activity to achieve Food Security in Mexico and the world, which is why authorities, researchers, farmers, beekeepers, and members are aware of the importance of bees. The Food and Agriculture Organization (FAO) says 100 crop species provide 90% of the food worldwide, and bees pollinate 71% of these3. It is for this reason, given by the engineer Manuel Ramirez Salcido, that bees have been presented as a parameter of environmental health, talking about ecology.


The Ministry of Agriculture, Livestock, Rural Development, Fisheries and Food (SAGARPA) says that if bees disappear there would be a food crisis; 84% of cash crops

depend on their pollination.4 In the same way, SAGARPA states that multiple varieties of fruit trees depend on cross-pollination that uses animals as vectors, such as bees; that is to say that there is an enormous amount of zoophilic plants.


According to the Ministry of Environment and Natural Resources (SEMARNAT), the links between the population, environment, and natural resources are mediated by multiple factors. The immediate environmental impact of urban settlements derives from a change in land purpose5, reducing the size of crops that can be pollinated by bees, generating an effect similar to that of habitat loss and with this, nutritional complications in bees, conferring susceptibility to diseases. This is one of the points suggested by the engineer Alejandro Bianchi during our meeting on June 15, 2018.


However, there are actions that seek to provide a healthy life for bees and their existence. There is a concern for the negative impact on anthophiles by irresponsible human activities; it is vital to prevent and attack the causes of bee reduction or loss at their roots. As we learned thanks to MEXMUN 2018, the objectives of the Convention on Biological Diversity should be used. These objectives are:

  1. Conservation of biodiversity.
  2. Sustainable use of the components of biological diversity.
  3. Appropriate transference of technologies.

Currently, the importance of carrying out a risk analysis is integrated in our legal plan, as per the Enviromental Risk Assesment Guide. In addition to the aspects mentioned in the assessment of the quality control within the legal plan, the following steps are involved, such as the guidelines for animal health risk analysis according to the Regulation of the Federal Animal Health Law, which are the following:

  1. Identification of the possible risks.
  2. Assessment of the chances that these risks arise.
  3. Evaluation of the consequences.
  4. Estimation of the possible global risk.
  5. The resolution of whether the risks are acceptable or not, as a whole, as well as the strategies for the management of possible risks.

Dr. Ernesto Tanus Sánchez mentioned the importance of avoiding the burning of hives, due to the limited accessibility to the wood with which they are made. Cedar, specifically red cedar (Cedrela odorata), is considered the best type of wood to make a hive. However, this species is subject to special protection according to NOM-059-SEMARNAT-2010, which means factors that negatively affect its viability may threaten it. Obtaining permission to perform the practice of incinerating hives becomes an arduous and even deficient process. Due to the virulence of Paenibacillus larvae, American Foulbrood sweeps entire hives before there is an answer by the authorities.


In other Latin American countries, the action plan presents variations. Ph.D. David De Jong explained us how in Brazil, it is not permissible for someone to incinerate a beehive if it is not a beekeeper, sometimes the firefighters do it in an emergency. Bryan Saavedra, mentioned how in Chile, they have the Agricultural and Livestock Service (SAG) who is in charge of incinerating hives in case the disease is present.
