[Relation between Muellerius capillaris infestation of molluscan intermediary hosts and of goats in Touraine].

32 dairy-goat farms of Touraine were investigated for Muellerius capillaris infection. Faecal and Molluscs samples were collected in Spring and Autumn. The factors of risk for goat were the abundance of Helix aspersa in Spring and of Deroceras reticulatum in Autumn. The infestivity of pasture was related to the infection of goat in Spring but not in Autumn. The faecal larval output in goats depended on the breed of goat at both periods; environmental factors were also of importance.
