Another aspect we wanted to analyse was to see the correlations between the following questions:


1. How often do the horse owners treat their horse(s) for parasitic infections?


2. Would the horse owners be open to a diagnosis method that involves genetically modified bacteria if it was proven to be cost-effective, safe and approved by the appropriate agency?


By studying how often horses are treated per year against respondents attitudes towards GMO, we set out to see if there is any correlation between these factors. The result shown in figure 2 indicates that there is no distinct dependence between these variables. We were expecting that eventually more frequent treatments would correlate to bigger acceptance of GMO suggesting possible wish for more effective/conclusive diagnostics. However it is suggested that openness for GMO is generally high irrespective of the chosen treatment frequency.

Another aspect we wanted to analyse was to see the correlations between the following questions:


1. How often do the horse owners diagnose their horse(s) for parasitic infections per year?


2. Would the horse owners be open to a diagnosis method that involves genetically modified bacteria if it was proven to be cost-effective, safe and approved by the appropriate agency?


Figure 3 depicts connection between how often horses are diagnosed per year and respondents attitudes towards GMO. Similarly to figure 2 there are no clear correlation between these factors.We can however see that the group performing no diagnosting has proportionally biggest fraction of respondents doubting GMO.

Figure 2. Correlation between the “frequency of treatment done for parasitic infections each year” towards “Their attitudes to using a GMO based diagnosis tool”. Number of treatments have the parameter <1 that corresponds to treatments occurring less often than once per year. NA stands for not applicable and are not numeric answers.

We also would like to analyse the correlations between the following questions:


1. Have the horse owners ever experienced or heard about a horse becoming severely ill or suffering complications caused by small or large strongyles (such as rapid weight loss, colic, diarrhea, inflammation, blood clots)? If yes, how many horses?


2. How often do the horse owners diagnose their horse(s) for parasitic infections per year


From figure 4 , we can see that most of the respondents diagnoses once or twice per year and about half of all respondents have heard about horses getting severely ill from Strongyle infections. This could indicate a result of the upcoming spread of resistance. This correlation also shows that people who have heard about 7 or more cases of severe illness among horses diagnose their horses twice a year. The correlation also show that the respondents who haven’t witnessed a severe strongyle infection personally, still choose to diagnose their horses for the infection. This is a positive sign since diagnosing is a working method to prevent the chances of spreading the resistance, by controlling the amount of parasites living in either paddocks or within the intestines of horses. This is positive for the proactive work that needs to be done in order to avoid unnecessary, fear induced, treatment contributing to resistance development.

Figure 4: The results shown in figure 4 indicates that there is no clear pattern in diagnosis frequency and experienced strongyle infections. We wanted to see whether higher exposure to infection cases correlates to more frequent diagnosting. “NA” stands for not applicable and are not numeric answers.


1. How often do the horse owners diagnose their horse(s) for parasitic infections per year?


2. Are the horse owners aware that using dewormers without an initial diagnosis contributes to resistance (the drug will stop being effective/useful) among parasites to these drugs?


We wanted to study whether people aware of resistance also tend to diagnose more often. In figure 5 we can follow this correlation in Sweden and Czech Republic. In Sweden majority of respondents were aware of resistance and no assumptions about this affecting number of diagnosis could be made. In comparison answers from Czech Republic were relatively heterogeneous. The group performing no diagnosis also contained a distinguishably large fraction of people unaware of resistance. This suggests that raising the awareness of resistance to a level of common knowledge could contribute to more frequent diagnosing and ultimately decrease risk of resistance development.

Figure 5: Correlation between the “frequency of treatment done for parasitic infections each year” towards “Their knowledge about resistant Strongyles”, to see if people aware of resistance also tend to diagnose more often. The figure to the left comes from the Swedish survey and the figure to the right comes from the Czech survey. Number of treatments have the parameter <1 that corresponds to treatments occurring less often than once per year. The parameter 3+ indicates that the treatments is done more often than 3 times per year. NA stands for not applicable and are not numeric answers.



We also analysed the correlations between the following questions:


1. On a scale of 1 to 5, how concerned are horse owners about strongyles (nematodes/deworming) becoming resistant to dewormers?


2. How often do the horse owners diagnose their horse(s) for parasitic infections per year


As previously seen in figure 6 awareness of resistance Sweden is generally high. However, worth to mention is that the few respondents that answered not believing in resistance were also found in the group using anthelmintics most frequently. In Czech Republic it is relatively more common with more frequent treatment.

Figure 6: Correlation between the “frequency of diagnoses done for parasitic infections each year” towards “the level of worry towards Strongyles”. The figure to the left comes from the Swedish survey and the figure to the right comes from the Czech survey. NA stands for not applicable and are not numeric answers.

2. How often do the horse owners treat their horse(s) for parasitic infections?


The results shown in figure 7 indicates that for the Swedish survey higher concern of anthelmintics resistance correlates with more frequent diagnosting. This indicates that the fear of resistance result in more diagnoses. When analysing the Czech it also shows that more worry among the horse owners result in a higher frequency of diagnoses per year. This indicates that the individual horse owners experiences a sense of security by having their horses diagnosed on a regular basis.

2. How often do the horse owners treat their horse(s) for parasitic infections?


The results shown in figure 8 indicates that most respondents do worry about resistance. However there is no clear trend correlating high concern to more careful treatment as the proportionally the amount of treatments remains approximately the same. This might indicate that the worries within the individual horse owner result in a higher frequency of treatments. When comparing to the Czech figure figure 8 also indicates that there is a general higher frequency of treatments. In addition the highest level of worry result in the the highest amount of horse owners who treat their horses more often than 3 times per year. Thereby there is a correlation between worry and treatment.
