| resistance of libyostrongylus douglassi in ostriches to levamisole. | while fenbendazole at 15 mg kg-1 either alone or in combination with resorantel reduced the total burden of libyostrongylus douglassi by more than 98%, levamisole alone at 30 mg kg-1 was only 28% effective, and in combination with resorantel its efficacy was 67%. these results with levamisole do not correspond with the registered rate of efficacy which is given as at least 80% in south africa. this is apparently the first reported case of anthelmintic resistance in ostriches. | 1988 | 3210219 |

| anthelmintic efficacy of fenbendazole against libyostrongylus douglassi and houttuynia struthionis in ostriches. | fenbendazole at a dosage rate of 15 mg fbz per kg body mass, was 99,7% effective against adult and 82,5% effective against 4th stage larvae (l4) of libyostrongylus douglassi. fenbendazole at the same dose removed scolices and strobila of houttuynia struthionis from 4 out of 5 treated birds and in the other there were only degenerating scolices, but all 5 untreated control birds were positive for h. struthionis. | 1985 | 3999107 |
