Lambs naturally infected with T. actinioides and naturally and experimentally infected with H. contortus were used in a controlled experiment to determine the anthelmintic activity of albendazole as compared with levamisole. The lambs were given 10,000 H. contortus larvae 25-35 days before treatment, were slaughtered 7-9 days after treatment, and were housed on concrete from the time of treatment until slaughter. In lambs given doses of 7.5 mg or 3.8 mg of albendazole/kg of 7.5 mg of levamisole/kg, reductions in numbers of H. contortus were 99, 85 and 98%, respectively. Reductions in numbers of T. actinioides were 98, 45 and 0%, respectively, as compared with untreated controls.
