The treatment of Stilesia hepatica infestation.

Sheep and goats naturally infested with Stilesia hepatica were treated with either praziquantel (Droncit, Bayer) or oxfendazole (Systamex, Coopers). Praziquantel at 15 mg/kg was 100% effective in 20 sheep; at 7,5 mg/kg 2 out of 20 sheep were still positive. Oxfendazole at 3,5mg/kg was ineffective. In spite of its efficacy the cost of praziquantel prohibits its routine use as an anthelmintic.
