Estimating the Prevalence and Factors Affecting the Shedding of Helminth Eggs in Irish Equine Populations.

Abstract: Gastrointestinal helminths are ubiquitous in horse populations across the world. Intensive anthelmintic treatments have succeeded in controlling some of the pathogenic effects of these parasites. However, the success of anthelmintic drugs has been threatened by the development of widespread resistance to those most commonly used. To develop improved control strategies, information on helminth distribution patterns is needed, which can be obtained by identifying animals regarded as high egg shedders and taking age, gender, and other risk factors into account. The aim of this study was to determine the prevalence of helminth infection in the Irish equine population using faecal egg counts and to evaluate the effects of risk factors on these faecal egg counts. For the 2700 horses that were included in the study, the prevalence of gastrointestinal helminth infection was 52.40%, 4.22%, 2.59%, and 0.89% for strongyle species, Parascaris spp., Anoplocephala spp., and Strongyloides westeri, respectively. Overall, strongyle faecal egg counts from 159 farms averaged 250.22 eggs per gram. Both age and season had significant effects on strongyle egg shedding. In conclusion, this study revealed high prevalence of strongyle worm infection in horses on Irish farms, which highlights the need to optimize and develop good management practices and strategic deworming.

Summary

This research study investigates the percentage of horses in Ireland infected with gastrointestinal helminths (worms) and identifies various factors that influence how many helminth eggs these horses shed. The findings reveal a high prevalence of helminth infection, especially strongyle species, and point towards the importance of better management practices and strategic deworming for horse health.

Study Objectives and Methodology

The primary aim of the study was to determine how common helminth infections were among horses in Ireland. This was carried out using a method called ‘faecal egg counts’, which involved examining horse droppings for the presence of helminth eggs. Another objective of the study was to evaluate how various risk factors could influence these faecal egg counts, thus affecting the degree of infection in affected horses. These risk factors included aspects like the horse’s age and gender, among others. Overall, the study included 2700 horses.

  • The study estimated prevalence of different types of helminth infections- strongyle species, , and .
  • It also looked at factors affecting horses’ egg shedding rates, including age and season.
  • This is particularly significant because high egg shedders can spread the infection in a population much faster.

Key Findings

The research revealed that majority of the horses in the study were infected by gastrointestinal helminths. The infections were largely due to strongyle species, with a prevalence of 52.40%. The other helminth varieties —, — were considerably less prevalent, with prevalences of 4.22%, 2.59% and 0.89% respectively.

  • The average count of strongyle faecal eggs across 159 farms was 250.22 eggs per gram.
  • Both age and season had significant statistical impacts on strongyle egg shedding.

Conclusions and Implications

The research concluded that the prevalence of strongyle worm infection in Irish horse populations was high. The presence of significant correlations between certain factors (such as age and season) and the level of egg shedding indicates that such factors could be important considerations in attempting to control helminth infection. The results highlight the need to optimize management practices and strategic deworming in horse populations to limit the impacts of these helminth infections.

As such, this study provides valuable insight into helminth infection rates and influencing factors among horses in Ireland. It could prove valuable in creating improved strategies for controlling these infections and promoting better equine health.
