A bacterial artificial chromosome library for Biomphalaria glabrata, intermediate snail host of Schistosoma mansoni.

To provide a novel resource for analysis of the genome of Biomphalaria glabrata, members of the international Biomphalaria glabrata Genome Initiative (http://biology.unm.edu/biomphalaria-genome.

Manganese superoxide dismutase from Biomphalaria glabrata.

The investigation of the response of Biomphalaria glabrata snails to Echinostoma paraensei (digenea) at 2 days post-exposure by suppression subtractive hybridization yielded a partial sequence of the anti-oxidant enzyme manganese superoxide dismutase (MnSOD). Full-length MnSOD (669nt) from M line and BS-90 strains of B. glabrata differed by one synonymous nucleotide replacement.

Differential expression of FREP genes in two strains of Biomphalaria glabrata following exposure to the digenetic trematodes Schistosoma mansoni and Echinostoma paraensei.

Fibrinogen-related proteins (FREPs) are hypothesized to function in non-self-recognition in the snail Biomphalaria glabrata. To investigate this assumption, the expression of four members of the FREP gene family was studied using quantitative PCR at 0.5-16 days following exposure of M line and BS-90 strain B.

Molecular identification of symbionts from the pulmonate snail Biomphalaria glabrata in Brazil.

The icthyosporean, Capsaspora owczarzaki, a known predator of Schistosoma mansoni sporocysts in vitro, is more prevalent in laboratory-reared strains of the intermediate snail host, Biomphalaria glabrata resistant to S. mansoni, than from the susceptible M line strain. We examined whether B.

The symbiont Capsaspora owczarzaki, nov. gen. nov. sp., isolated from three strains of the pulmonate snail Biomphalaria glabrata is related to members of the Mesomycetozoea.

While investigating the resistance of some strains of Biomphalaria glabrata to infection with Schistosoma mansoni, a unicellular eukaryotic symbiont was noted in the snail haemolymph. It was similar in appearance to Nuclearia sp. reported from B.
