[Epidemiologic data on distomiasis due to Fasciola gigantica Cobbold on the island of Madagascar. Infestation of cattle between 1975 and 1981].

Stools examinations of zebus were made in Madagascar between 1975 and 1981 for determining the importance of Fascioliasis gigantica in the six provinces of the island during this time. High percentages of F. gigantica eggs were found in the stools of the different infected zebus-herds of five provinces. No fasciolid infection was noted in 1979 in the cattle of the province of Diego-Suarez. Differences were noted between the infection rate obtained by fecal examination and the rate indicated in the veterinary reports. The significance of these results is discussed.
