Abstract
Au cours de l'évolution de la parasitose, le sporocyste deS. mansoni subit des modifications morphoanatomiques conduisant à une sectorisation de ce stade larvaire en 3 zones: une zone antérieure en forme de manchon terminal où se situe le pore de sortie des cercaires; des zones dilatées où s'effectue la cercariogenèse et des zones contractées dépourvues d'embryon cercarien. L'étude en microscopie photonique et électronique de ces zones montre des différences dans l'organisation de la structure tégumentaire. Le rôle de ces différents secteurs est discuté dans le cadre de la dynamique des populations larvaires et des processus de reconversion des sporocystes. During the larval development ofS. mansoni in the snail host, morphoanatomic changes occur in the daughter sporocyst by a sectorization of this larval stage. Three sectors can be distinguished: an anterior zone with a well-differentiated birth pore; dilated zones containing the developing cercariae; constricted zones without cercarial embryo. The photonic and electronic microscopical study shows variations in the tegumental structure of these sectors. This evolution of the daughter sporocysts is discussed in relation with the dynamics of larval stages and the replication process of sporocysts.This publication has 12 references indexed in Scilit:
