Trematodes have complex life cycles with infective stages in multiple hosts including species of conservation concern. We conducted a field survey of seven ponds in Teton County, Wyoming for trematode prevalence and richness. We collected snails from each location and determined trematode prevalence by shedding snails and determined trematode richness by dissection of infected snails. At each l...

Fasciolosis is a parasitic helminthes disease caused by Fasciola gigantica. The different larval stage (sporocyst, redia and cercaria) are found in intermediate host snail Lymnaea acuminata. In the present study it has been tried to kill the F. gigantica larvae in vitro/ in vivo condition by the use of ferulic acid there is no mortality of snails. Mortality of larvae in in vivo and in vitro con...

background: human echinostomiasis is an intestinal disease caused by the members of family echinostomatidae parasites. the aim of present research was to identify echinos­tomatidae cercariae emitted by lymnaea palustris snails from mazandaran province in the north of iran based on the morphological and morphometrical charac­teristics of the different stages of experimental parasite life cycle. ...

A survey for freshwater gastropods carrying trematodes parasites was conducted in Manso Dam and the surrounding areas frequented by tourist, focusing particularly on the Pantanal region. Infected snails were recovered from twelve of the eighteen investigated municipalities and forty-one cercaria-snail pairings were recorded. Among these pairings were several first records of snails serving as i...

As one of the three major human pathogens that cause schistosomiasis, Schistosoma japonicum is the only one that is endemic in China. Despite great progress on schistosomiasis control over the past 50 years in China, S. japonicum transmission still occurs in certain endemic regions, which causes significant public health problems and enormous economic losses. During different life stages, paras...
