Anthelmintic activity of a single subcutaneous injection of closantel at the dose of 2.5 milligrams per kilogram of body weight was determined by the critical test method against Fasciola gigantica and other parasites in 5 naturally infected cattle. Closantel was shown to remove 100 per cent of mature F. gigantica. The drug was also 100 per cent effective against mature Mecistocirrus digitatus, Oesophagostomum radiatum and Bunostomum phlebotomum, whereas it was ineffective against Paramphistomum spp.
