Wa. Rahman, RESISTANCE TO BENZIMIDAZOLE ANTHELMINTICS BY HAEMONCHUS-CONTORTUS IN GOATS IN PENINSULAR MALAYSIA, Veterinary parasitology, 55(1-2), 1994, pp. 155-157
A previous study had suggested that local strains of goat trichostrong
yles, comprising largely Haemonchus contortus, might have developed re
sistance to benzimidazole anthelmintics. A trial involving 18 goats wa
s conducted to confirm this. There was a significant (P < 0.01) reduct
ion in worm burdens in goats given levamisole, but this was not so for
those animals given albendazole, fenbendazole, oxfendazole and mebend
azole (P > 0.05).
