National survey and molecular diagnosis of Echinococcus granulosus sensu lato in livestock in France, 2012

Abstract : Abstract The parasitic species of the Echinococcus granulosus sensu lato (sl) complex are the causative agents of cystic echinococcosis in humans. The lifecycle of E. granulosus sl is essentially domestic, and is based on the consumption by dogs of hydatid cysts in viscera of livestock species. The aim of this study was to survey E. granulosus sensu lato in livestock in France. A 1-year national survey of E. granulosus sl in livestock at the slaughterhouse was organized in 2012 in France, with systematic molecular confirmation. The prevalence of E. granulosus ss nationally was 0.002% in sheep, mainly focused in the Alpine area, and 0.001% in cattle, with the distribution of cases throughout the country. Echinococcus canadensis G6/7 was observed only in Corsica in pigs, with a prevalence of nearly 1% in the island. A national prevalence of 0.0002% was estimated for E. ortleppi in cattle, due to seven cases distributed in two foci. The results of this survey are of particular interest because of the zoonotic risk associated with the presence of these parasite species, for which systematic control at the slaughterhouse should enable their elimination.
