Anthelmintic resistance is commonly reported in horse populations developed countries, but evidence some working either lacking or inconclusive.To estimate prevalence of GI nematode infections horses Egypt and to evaluate strongyle ivermectin, doramectin fenbendazole.Cross-sectional study.Faecal egg count was performed on 644 from 2 provinces Egypt. A short questionnaire about signalment worming history completed for each horse. Horses identified with ≥50 type egg/g (n = 146) underwent faecal reduction testing (FECRT) following treatment ivermectin 33), 33) fenbendazole 30). Risk factors (≥200 egg/g) Parascaris equorum (>0 infection were investigated using multivariable logistic regression analyses.The low (0-199 epg), medium (200-500 epg) high (>500 88.4%, 5.9% 5.8%, respectively. P. eggs detected 5.1% horses. Strongyle FECR 100%, 99.97% 100% the 12 months preceding examination associated reduced likelihood (odds ratio [OR] 0.26, 95% confidence interval [CI] 0.14, 0.47, P < .001). The significantly horses' age (OR 0.78, CI 0.69, 0.90; Male more likely have 2.86, 1.37, 5.93, .005).Nonrandomised selection study areas larval cultures unsuccessful samples.There no macrocyclic lactones benzimidazole strongyles studied population.
