Eguale T, Chaka H, Gizaw G, Sibhatu D, Evaluation of anthelminths on sheep nematodes in Ethiopia, Online J Vet Res., 14 (2): 270-276, 2010. Albendazole, tetraclozan and tetramisole were evaluated against sheep nematodes in Ethiopia. Animals were balanced for fecal egg count (FEC), and fecal egg count reduction tests (FECRT) were performed. There was a 99-100% reduction in the FEC 10 days with albendazole and tetraclozan and 93.1% with tetramisole (in one locality). The efficacy of tetramisole and tetraclozan varied between localities but there was no significant difference (p>0.001) in mean fecal egg count. No eggs were found 10 days post-treatment in albendazole treated groups, but some were found in tetraclozan and tetramisole treated sheep. The results suggest that there may be some localized resistance to tetramisole. Continuous monitoring is required to avoid inducing helminth resistance.
