<h2> Vidilab </h2>
<p> Vidilab (a veterinary diagnostics company) was consulted at multiple points in our project. From the very beginning when we didn’t even have a project to the very end of our lab period in august we talked with both management (the CEO, Bitte Ljungström) and researchers at the company (Alice Anlind, Sara Hägglund Ljungström). From these discussions, we learned what the major issues of the field were and how large the need was for a new diagnostic tool for small strongyles. In the end this was the reason why we decided to take up the fight against these parasites. </p>

<p> Initially, our project focused mainly on small strongyles and <i>in vitro</i> diagnosis of the encysted larvae. From the literature we understood that small strongyles formed cysts containing hundreds of individual worms in the intestinal tract of horses. It was these cysts that we initially planned to detect and isolate from horse tissue and co-culture them with bacteria.</p>

<p> Vidilab was kind enough to provide access to horse tissue with encysted larvae. The cysts we received did not correspond with what we initially expected due to our previous research. Because of this, we decided to focus on detection of the worms rather than the cysts. But as we knew, free floating small strongyles do not put the horse into significant danger. Instead we decided only to focus on providing farmers with better information about their horses’ wellbeing. Thanks to Vidilab we also knew that the usage of anthelmintics is leading towards resistance development in the strongyle population, turning them into a threat to the equine industry and horses’ physical health. By administering more accurate treatments, the resistance development rate among the strongyles could possibly be decreased.</p>

<p> During our second visit to Vidilab they also informed us about the difficulties with detecting large strongyles since all current techniques are based on egg counting in grass samples. After some consideration we outlined a strategy to battle this problem as well. First of all we wanted to investigate the need for a better preventative tool for large strongyle infections. In order to gather the data we worked on market analysis based on a survey that we spread among horse owners in Sweden. Secondly, we wanted to try and see if a similar system as we outlined for the small strongyles could work with large strongyles present in grass, hence we made an analysis of the visibility of fluorescent proteins in grass sampling. </p>

<h3> Horse Owners </h3>
<p> We used every opportunity we had at our disposal to discuss our project with horse owners. From these discussions we learned about the best ways of isolating samples and about the difficulty of isolating urine from a horse. We therefore moved on to investigating detection methods in feces. These interviews also first gave us the idea to start investigating on a larger scale to what extent the horse owners are aware of issues related to strongyle infections &mdash; and the idea of conducting a market analysis was born. </p>

<p> Also, to advocate our stance that the amount of treatments can be optimized, we needed to know the mean amount of treatments performed on each horse per year. We received this data as part of our market analysis. Our predictive model simulating the extent of strongyle infection depending on the amount of anthelmintic treatments suggests that the current situation can indeed be optimized. Fewer treatments than the average today would decrease risk of developing anthelmintic resistance and still keep the horses healthy. </p>

<p> The market analysis gave us insight of the horse-owners perspective and the objective data that we needed to draw our conclusions. We used the data from the survey to confirm our project strategy and to build our different models. </p>

<p>The purpose of our project was to combat the systematic overuse of anthelmintics [1] and thus also address the growing resistance against such compounds.

                             <p>The resistance against anthelmintics might also be a problem for humans in the future [4] which increases motivation for a new diagnosis and/or treatment approach. This is “good” news since the organism used in our project (namely <i>E. coli</i>) are inherent to the microbiome of humans and horses alike. We believe that a new, specific and potentially eco-friendly method of diagnosis or treatment would have a positive outcome on society as a whole. This could lower the degree of stress and potential suffering for animals that get infected as well as for their human owners.</p>

                 <p> There are however some concerns in public about <i>E. coli</i> being pathogenic or a transmitter of disease. It’s often the incidence when <i>E. coli</i> contaminated meat for consumption gets coverage in news media. It is thus a challenge when conveying a complex topic to the public which demands some scientific knowledge, especially in biology and is something our Human Practise group has been challenged with throughout the project. The risks using <i>E. coli</i> and its given traits for this project are discussed further throughout the text. </p>

                 <h2> GMO, Welcomed by the Public </h2>
                 <p> By authoring and distributing a survey to horse owners we could see that the majority of respondents in Sweden had positive attitudes (83.2 %, 368 respondents) towards a GMO-type of diagnosis method. The survey also showed a public fear of growing anthelmintics resistance against blood worms(strongyles) (77.3% of 370 respondents ranked their fear as 4 or 5 were 5 being the most concerned). </p>

                 <p> Nothing that is considered toxic or harmful was genetically introduced (UnaG, amilGFP) into our E.coli. However, for cultivation and selection purposes used in common synthetic biology practical work, antibiotic resistance was also introduced which presents a risk in the potential spread of antibiotic resistance (Chloramphenicol, Ampicillin, Tetracycline) if these plasmids were to spread into the environment. This was avoided to a large degree by following standard lab practise with specific guidelines regarding waste disposal of GMOs.  </p>

                 <p> The ability for proliferation of GMOs and organisms in general is determined by their fitness. As a rule of thumb regarding the spread of GMOs in the environment, fitness is greatly reduced for most lab strains of microorganisms because they have been modified in numerous ways to make them easy to work with. These are not adaptations that are suitable for their natural environment, giving them a negative fitness contribution [9].
