Mode de pénétration et localisation des larves de Morerastrongylus andersoni (Petter, 1972) (Metastrongyloidea, Nematoda) chez l’hôte intermédiaire
Way of penetration and localization of Morerastrongylus andersoni (Petter, 1972) larvae (Metastrongyloidea, Nematoda) in the intermediary host

Le mode de pénétration et la localisation des larves de Morerastrongylus andersoni (Petter, 1972), Angiostrongylinae parasite de Rongeurs Gerbillidae africains, sont étudiés chez les Limnaea stagnalis L. et Planorbarius corneus (L.). La pénétration se fait par ingestion : en effet, chez des Mollusques sacrifiés immédiatement après un contact d’une demi-heure à une heure avec des crottes de Rongeurs infestés, la majorité des larves se trouvent dans le tube digestif. Après quelques heures, les larves se localisent dans le tissu conjonctif et dans les muscles du céphalopodium, de la masse viscérale et du manteau.
Abstract
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.
