Schistosomiasis is a parasitic disease that affects 143 million people in endemic countries. This work analyzed overexpressed sequences from the cercaria phase to early schistosomulum using bioinformatics tools predict host interaction and selected proteins for predicting T cell epitopes. The final peptides were chemically synthesized, their toxicity was evaluated vitro. Peptides formulated Adj...

In adult fish trematode Crepidostomum metoecus (Braun, 1900) two pigmented eyespots were detected dorso-laterally to the pharynx. In contrast to most other digenetic trematodes the eyespots in C. metoecus persist throughout the life (cercaria, metacercaria, adult), but their role in the biology of the adult trematode is uncertain. The ultrastructure of the eyespots in Digenea has been studied i...

During late summer in 1995 to 1997, repeated outbreaks of maculopapular skin eruptions were noted on the legs of children after wading in the pond in the Family Park in Laugardalur, Reykjavík, Iceland. Clinical symptoms developing on the legs resembled those of cercarial dermatitis. An examination of Lymnaea peregra snails from this pond and from the adjacent Lake Tjornin resulted in detection ...

Adults of Schistosoma edwardiense Thurston, 1964, were recovered from Hippopotamus amphibius in the Kruger National Park. Small round to oval Schistosoma margrebowiei-like eggs, presumed to be those of S. edwardiense, were found fairly frequently in the faeces of infected hippopotami together with a few Schistosoma haematobium-like eggs the identity of which remains uncertain. Biomphalaria sp.,...

Lymnaea elodes snails collected in northern Indiana, U.S.A., were infected with larval stages of an echinostome bearing 37 collar spines and resembling members of the Echinostoma group. The taxonomic status of this digenean was determined through experimental infections of various definitive and first-intermediate hosts. In addition, characteristics of the penetration and paraesophageal glands ...
