Summary
The given research article investigates the prevalence and intensity of helminth infections, specifically strongyle, Oxyuris equi and Parascaris equorum species, in working horses in lowland Lesotho, relative to horse’s age, sex and the usage of anthelmintics.
Research methodology
In the study, the researchers undertook several specific steps:
- A cross-sectional survey was conducted by collecting fresh faecal samples from 305 randomly selected horses.
- Worm egg counts were performed using a validated field laboratory kit, which enabled the researchers to determine the level of helminth infection in the horses.
- A standardised face-to-face owner questionnaire was used to gather information about the use of anthelmintics, which are drugs that expel parasitic worms from the body by stunning or killing them.
- The prevalence estimates for each species of the helminth infection were calculated, as were infection intensity estimates for the strongyle species.
- Logistic regression was used to identify relationships between the exposure variables (age, sex, and anthelmintics use) and infection status/intensity.
Findings
The study revealed several key findings:
- The strongyle infection was prevalent in 88.2% of the horses, with an infection rate varying from low to high – 1-500 eggs per gram (epg) in 19.7%, 501-1,000 epg in 19.7% and >1,001 epg in 48.8% of the infected horses.
- The use of proprietary equine anthelmintic products was significantly associated with decreasing strongyle infection intensity (OR 0.18, 95%CI 0.11-0.30, p<0.0001).
- The Oxyuris equi infection was less common, found in only 6.2% of the horses, and its risk decreased with increasing horse age (OR 0.84, 95%CI 0.72-0.97, p = 0.02).
- The Parascaris equorum infection was seen in 21.6% of the horses, with no significant associations with the investigated exposure variables observed.
Conclusion
Based on these results, the study concluded that strongyle infection is endemic in working horses in lowland Lesotho, but can be managed effectively through the use of proprietary equine anthelmintics. The lack of age-acquired immunity to Parascaris equorum infection raises questions that may deserve further investigation. Additionally, while Oxyuris equi infection is not as widespread as the other two, implementing measures to protect younger animals from this parasite may be beneficial.
