Establishment of Biomphalaria tenagophila snails in Europe. [PDF]
Emerg Infect Dis, 2008 To the Editor: Schistosomiasis, known since ancient times, is caused by blood flukes (Trematoda: Schistosomidae). It is a major communicable disease with public health and socioeconomic effects in the developing world (1). Among parasitic diseases, schistosomiasis ranks second only to malaria with regard to the number of persons infected and at risk ...

Estivação de Biomphalaria tenagophila (Pulmonata, Planorbidae) [PDF]
Revista De Saude Publica, 1989 É relatado o encontro de Biomphalaria tenagophila estivada, em dois municípios do Estado de São Paulo (Brasil): Ubatuba e Conchas. Essa característica etológica foi percebida em 15 exemplares coletados em Ubatuba e 6 em Conchas. Os caramujos estavam enterrados em fendas do solo ressecado,e, em laboratório, voltaram a exibir vitalidade depois de ...

Interaction of Biomphalaria cells in primary cultures with Schistosoma mansoni sporocysts [PDF]
Revista da Sociedade Brasileira de Medicina Tropical, 2020 INTRODUCTION: Biomphalaria snails may display varying levels of susceptibility to Schistosoma mansoni infection. We have been developing an in vitro model to study the interaction between the snail and the parasite, using tissue-derived cell cultures ...

Morphological characterization of the hemocytes of the pulmonate snail Biomphalaria tenagophila [PDF]
Memorias Do Instituto Oswaldo Cruz, 1993 The blood cells of the pulmonate snail Biomphalaria tenagophila, an important transmitter of the trematode Schistosoma mansoni in Brazil, were examined by light and transmission electron microscopy (TEM). Two hemocyte types were identified: hyalinocytes and granulocytes. Hyalinocytes are small young (immature), poorly spreading cells, which have a high

Development of Schistosoma mansoni in Biomphalaria tenagophila, Biomphalaria straminea and Biomphalaria glabrata [PDF]
Revista Do Instituto De Medicina Tropical De Sao Paulo, 1995 A comparative study of the development of Schistosoma mansoni during the intra-molluscan phase was made by means of histological sections of Biomphalaria tenagophila, B. straminea and B. glabrata from Brazil. Two hundred snails of each species were individually exposed to 50 miracidia of the S. mansoni, AL line.

The effect of early infection with Echinostoma paraensei on the interaction of Schistosoma mansoni with Biomphalaria glabrata and Biomphalaria tenagophila [PDF]
Memorias do Instituto Oswaldo Cruz, 2010 Infection caused by the trematode Echinostoma paraensei has been shown to interfere in the natural resistance to infection by Schistosoma mansoni. Biomphalaria glabrata is susceptible to infection, while Taim isolate Biomphalaria tenagophila is resistant

Susceptibility of Biomphalaria tenagophila and Biomphalaria straminea to Schistosoma mansoni infection detected by low stringency polymerase chain reaction [PDF]
Revista Do Instituto De Medicina Tropical De Sao Paulo, 2000 In order to determine Schistosoma mansoni infection rates in Biomphalaria tenagophila and B. straminea, low stringency polymerase chain reaction (LS-PCR) technique was used as a complementary method to light exposure technique. LS-PCR has already been standardized in our laboratory to detect the trematode DNA in B. glabrata. Higher S. mansoni infection

Compatibility of Biomphalaria tenagophila with Schistosoma mansoni: a study of homologous plasma transference [PDF]
Memorias do Instituto Oswaldo Cruz, 2006 This study aims to investigate the importance of the serum factors present in the plasma of resistant Biomphalaria tenagophila snails, when transferred to susceptible conspecific. Susceptible B.
