Conteúdo: | Strains of Trichostrongylus colubriformis (designated PF4) and Ostertagia sp (O circumcin- cta/O trifurcata, designated PF5), with varying degrees of resistance to levamisole, moran- tel tartrate and thiabendazole were isolated  into pure culture. Detailed dose response stu- dies showed that both T colubriformis and Ostertagia sp were highly resistant to levamisole and morantel with low level resistance to thiabendazole. The effective dose required to re- move 80 per cent worm burdens (ED80) was calculated for each anthelmintic. For T colu- briformis the ED80 for levamisole and thiabendazole were 12.6 and 40. 1 mg/kg respecti- vely. For Ostertagia sp, the ED80 for levamisole, thiabendazole and morantel were 20.4, 45.2 and 35.8 mg/kg respectively. The implication of these results are discussed with re- ference to alternative means of chemical control.
