Abstract
A total of 4149 Lymnaea auricularia var rufescens and 401 L. luteola snails were collected and examined in six periods from May, 1989 to April, 1990 at Savar, Dhaka, Bangladesh. Fasciola cercariae (Gymnocephalous cercariae) was found in 13 (0.31%) L. auricularia var rufescens, but was absent in all L. luteola examined. Prevalence of Fasciola cercariae in the snails varied significantly (p<0.05) in different periods (months) of the year with higher prevalence in July-August (0.77%), followed by September-October (0.52%) and May-June (0.45%). Cercariae did not appear in the snails from November to April.
