Gastrointestinal Strongyles Egg Excretion in Relation to Age, Gender, and Management of Horses in Italy.

Abstract: Current equine helminth control strategies play a key role in strongyle epidemiology and anthelmintic resistance and have led to the recommendation for new treatment plans, which include diagnostic and efficacy surveillance. Assessing the equine strongyle distribution patterns would thus be useful and this study describes the strongyle prevalence in the equine population in Italy through coprological analysis and coproculture. In addition, individual data on each animal were collected in order to identify risk factors associated with strongyle egg shedding. Of the total number of stables investigated, 86.4% were found to have at least one positive animal and a 39.5% prevalence of strongyle egg shedding with a mean eggs per gram (EPG) of 245. A total of 80% of the total recorded EPG was shed from 12.8% of positive horses, thus confirming the need for new targeted intervention strategies. Significant differences in parasite prevalence were found based on season, sex, geographical distribution, management and rearing system, and breed. Significantly lower EPG values were found in horses that had received anthelmintic treatment, and macrocyclic lactones (MLs) were the most effective. Lastly, although large strongyles are more pathogenic, horses in Italy are mainly burdened by small strongyles, which pose an important animal health risk requiring continuous parasitological monitoring.

This research investigated the prevalence and distribution of strongyle parasites in the horse population in Italy. It found a significant number of horses were excreting strongyle eggs and identified various risk factors related to this parasitic infection, including age, gender, and management strategies, among others.

Overview of the Study

  • This study focused on strongyle parasites, which are of significant health concern for horses. It sought to describe their distribution in the equine population in Italy through coprological analysis (the study of feces) and coproculture (growing parasites from feces in a lab setting).
  • The researchers collected individual data from each horse to pinpoint potential risk factors associated with strongyle egg shedding. The aim was to provide valuable insights that can guide more targeted and effective intervention strategies.

Key Findings

  • The study established that 86.4% of the stables investigated had at least one horse testing positive for strongyle eggs. In terms of the overall equine population, the prevalence of strongyle egg shedding was 39.5%, with an average of 245 eggs per gram.
  • Interestingly, 80% of the total recorded egg shedding came from 12.8% of the positively tested horses. This finding reinforces the importance of targeted interventions in controlling strongyle parasites.
  • Significant variations in parasite prevalence were found depending on factors such as season, sex, geographical location, management and rearing system, and breed of the horse. Hence, these factors should be considered in the development of parasite control strategies.
  • Anthelmintic treatment, particularly macrocyclic lactones (MLs), showed efficacy in reducing egg shedding. Notably lower egg counts were reported in horses that had received such treatment.
  • While large strongyles are more pathogenic (disease-causing), small strongyles were found to be the main burden for horses in Italy. Therefore, continuous parasitological monitoring is crucial to address this significant animal health risk in the region.
