Phylogenetic analysis of Biomphalaria tenagophila (Orbigny, 1835) (Mollusca: Gastropoda) [PDF]
Mitochondrial DNA of Biomphalaria tenagophila, a mollusc intermediate host of Schistosoma mansoni in Brazil, was sequenced and characterised. The genome size found for B.

Establishment of Biomphalaria tenagophila snails in Europe. [PDF]
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]
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]
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]
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

Breeding of Biomphalaria tenagophila in mass scale [PDF]
An efficient method for breeding Biomphalaria tenagophila (Taim lineage/RS) was developed over a 5-year-period (2005-2010). Special facilities were provided which consisted of four cement tanks (9.4 x 0.6 x 0.22 m), with their bottom covered with a layer of sterilized red earth and calcium carbonate.

The effect of early infection with Echinostoma paraensei on the interaction of Schistosoma mansoni with Biomphalaria glabrata and Biomphalaria tenagophila [PDF]
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

Characterization of South American Snails of the Genus Biomphalaria (Basommatophora: Planorbidae) and Schistosoma mansoni (Platyhelminthes: Trematoda) in Molluscs by PCR-RFLP. [PDF]
The identification of snails of the genus Biomphalaria can be done using morphological characteristics which depends on the size of the snails and skill and knowledge of researcher. These methods sometimes are not adequate for identification of species.

Specific Identification of Biomphalaria tenagophila and Biomphalaria occidentalis Populations by the Low Stringency Polymerase Chain Reaction [PDF]
Although Biomphalaria occidentalis and B. tenagophila are indistinguishable on the basis of shell morphology and the majority of their genital organs, only the latter is susceptible to infection with Schistosoma mansoni. Thus, the identification of these species is fundamental to epidemiological studies of schistosomiasis. Here we describe a simple and
