The anthelmintic efficacy of cambendazole in horses

Summary

The anthelmintic activity of cambendazole 31% paste was evaluated in a controlled trial against naturally acquired gastro-intestinal parasites of the horse. Four groups of five adult horses were treated at dose rates of 0, 15, 20 and 25 mg/kg. The three dose levels of cambendazole tested were efficacious against the large strongyles Strongylus edentatus and S. vulgaris, the stomach worm Trichostrongylus axei, the pinworms Oxyuris equi and Probstmayria vivipara and all the species of small strongyles present. No efficacy was demonstrated against the tapeworm Anoplocephala perfoliata or the horse bots Gasterophilus intestinalis or G. nasalis
