Susceptibility of Biomphalaria straminea (Dunker, 1848) from Serra da Mesa Dam, Goiás, Brazil to infection with three strains of Schistosoma mansoni Sambon, 1907

Abstract

Ecological changes from water resources development projects often affect the epidemiology of water-associ

A malacological survey in the Manso Power Plant, State of Mato Grosso, Brazil: new records of freshwater snails, including transmitters of schistosomiasis and exotic species

“…schistosomiasis to non-endemic areas in Brazil via the introduction of vector snails was reported by Fernandez and Thiengo [10][11] , who observed different degrees of susceptibility to Schistosoma mansoni Sambon, 1907 in an experimental infection of B. straminea from three different reservoirs in the Upper Tocantins river basin. Three species of Biomphalaria that play a role in the transmission of S. mansoni in Brazil were recently found in the Pampulha reservoir, which is a potential urban focus of schistosomiasis located in the municipality of Belo Horizonte, State of Minas Gerais 12 .…”

Susceptibility of Biomphalaria amazonica and Biomphalaria occidentalis from Manso Dam, Mato Grosso, Brazil to infection with three strains of Schistosoma mansoni

“…It is impossible to predict accurately the changes that might occur and whether an environment suitable for a snail intermediate host of schistosomiasis will develop, however in countries where the infection is endemic it is prudent that investigations be realized, including studies involving parasite-mollusc compatibility. Although in Brazil such studies are still scarce, Fernandez and Thiengo (2002) demonstrated the possibility of Biomphalaria straminea (Dunker, 1848), found in the lake of Serra da Mesa hydroelectric power station, state of Goiás, to act as a vector of schistosomiasis in that area.…”

Biological implications of the phenotypic plasticity in the Schistosoma mansoni - Nectomys squamipes model

“…Our results showed that CM strain presented highest egg excretion level than other strains. FERNANDEZ & THIENGO 11 have proved that five populations of Biomphalaria straminea from Goiás State located in the central part of Brazil were susceptible to this schistosome strain. Only CMO strain showed lower egg count in the large intestine.…”
