[Mode of penetration and localization of the larvas of Morerastrongylus andersoni (Petter, 1972) (Metastrongyloidea, Nematoda) in the intermediate host]. / Mode de pénétration et localisation des larves de Morerastrongylus andersoni (Petter, 1972) (Metastrongyloidea, Nematoda) chez l'hôte intermédiaire

The way of entry and the localization of the larvae of Morerastrongylus andersoni (Petter, 1972), parasite of African Gerbillidae Rodents, were studied in Limnaea stagnalis L. and Planorbarius corneus (L.). The entry occurs by ingestion: indeed, in the Molluscs killed immediatly after one-half to one hour contact with infested Rodents; droppings, the majority of the larvae are found in the digestive tract. After several hours, the larvae are located in the connective tissue and in the muscles and they are distributed everywhere in the Mollusc's body.
