Biomphalaria glabrata snails were collected by Omar dos Santos Carvalho (CPRR/Fiocruz) in the south east of Brazil (19o59' S 44o02' W), Belo Horizonte, district of Barreiro. Morphology-based species identification was confirmed by PCR_RFLP; 16S rDNA, NADH dehydrogenase 1 sequences (AY737280, AY737281). Lab-reared offspring of the wild caught snails proved susceptible to multiple strains of Schistosoma mansoni. BB02 snails are maintained as inbred lines at several research groups. A BAC library is available for this strain from the Arizona Genomics Institute (Tucson AZ, USA).

Genomic DNA was extracted from whole body soft tissues minus the reproductive organs of adult BB02 snails (Coen Adema, UNM) and applied for genome sequencing at The Genomics Institute (TGI), Washington University, St Louis MO.

Biomphalaria glabrata

Freshwater snails of the genus Biomphalaria are intermediate hosts for flatworm parasites of the genus Schistosoma, causative pathogens of human schistosomiasis, in South America, the Greater and Lesser Antilles, Africa, Madagascar and the Arabian peninsula. Biomphalaria glabrata, a neotropical snail, is the major intermediate host of Schistosoma mansoni.
