Equine Verminous Arteritis. An Arteriographic Evaluation of the Larvicidal Activity of Albendazole

Abstract
Albendazole was an effective larvicidal anthelmintic against the fourth stage Strongylus vulgaris larvae as late as 1 mo. post-infection. The drug was administered at a dose rate of 25 mg/kg 3 times daily for 5 days. Diarrhea occurred in 3 of 4 foals treated and of these 1 died during belated i.v. therapy for dehydration. Arteriography allowed for an in vivo assessment of the development and regression of lesions in infected-treated foals compared to the continued development of lesions in infected-untreated foals. The arteriographic findings were confirmed at necropsy.
