The cercariae of five flukes, which are potential human parasites, Opisthorchis viverrini (family Opisthorchiidae), Haplorchis taichui (Heterophyidae), Schistosoma spindale (Schistosomatidae), Fasciolopsis buski, and Fasciola gigantica (Fasciolidae) were found in freshwater snails from Laos. The cercariae of the above species, recorded in Laos for the first time, are illustrated and their morphology is briefly described. The snail Helicorbis umbilicalis represents a new intermediate host of F. buski. The occurrence of medically important snails in the Vientiane province will also be discussed.
Résumé
Les cercaires de cinq espèces de Distomes (Trematoda) : Opisthorchis viverrini (Opisthorchiidae), Haplorchis taichui (Heterophyidae), Schistosoma spindale (Schistosomatidae), Fasciolopsis buski et Fasciola gigantica (Fasciolidae) ont été trouvées dans des Gastropodes du Laos. Ces cercaires trouvées au Laos pour la première fois sont décrites et dessinées. La Gastropode Helicorbis umbilicalis représente un nouveau hôte premier intermédiaire pour Fasciolopsis buski. L’apparition des Gastropodes d’importance médicale dans la province de Vientiane est aussi mentionnée.
