Abstract
A comparative study of the shedding of cercariae ofSchistosoma haematobium was performed inBulinus truncatus andPlanorbarius metidjensis individually exposed to 5 miracidia in their first 72 h of life. No significant difference was noted between the mean values of the two snail groups concerning the prepatent period duration (53–57 days at 24°–26°C), the patent period duration (41 days forB. truncatus, 70 days forP. metidjensis), or the total number of cercariae (1, 499 perB. truncatus 1,935 perP. metidjensis). Successive periods of heavy and low production were encountered in the shedding of cercariae; however, the periodicity was identical in the two snail species (25–27 days) and the emergence of cercariae peaked between 11 a.m. and 1 p.m.
