Experimental and Molecular Study of Cercariae of Clinostomum sp. (Trematoda: Clinostomidae) from Biomphalaria spp. (Mollusca: Planorbidae) in Brazil

摘要: Abstract:  Despite the large number of reports species Clinostomum from vertebrate hosts in South America, studies evaluating molluscan transmitters these parasites are scarce. In present study, clinostomatoid cercariae shed 0.02% (4/17,485) specimens Biomphalaria spp., collected at Pampulha reservoir, Belo Horizonte, Minas Gerais, Brazil, were used for experimental infection Poecilia reticulata. Samples molluscs and metacercariae experimentally obtained fish subjected to morphological molecular analyses compared with reported Americas. The metacercariae, here identified as sp., general morphology similar that marginatum, however, point view, differ significantly North American C. marginatum other America. These results suggest diversity found Brazil may ...
