Biomphalaria straminea is a species of air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Planorbidae, the ram's horn snails.

This snail is a medically important pest,[1] because an intermediate host for the parasite Schistosoma mansoni and a vector of schistosomiasis.[2]

The history of these discoveries was summarized by Paraense (2001).[3]

The shell of this species, like all planorbids is sinistral in coiling, but is carried upside down and thus appears to be dextral.

Distribution

Biomphalaria glabrata is a Neotropical[1] species. It occurs in:

Caribbean: Saint Lucia – reported since 1993[4]
northeast of Brazil

This species has recently expanded its native range.[1] As an introduced species, it occurs in:

Hong Kong and Southern China - firstly collected in 1973[5] in the Lam Tsuen valley in Hong Kong, in has now been identified at a number of locations in Hong Kong and Guangdong Province.[6]

Phylogeny

To allow comparisons with other mollusc genomes, a high-quality genome assembly for B. straminea together with accompanying transcriptomes has been sequenced, producing a 1.005 Gb in size reference genome consisting of 36 chromosomes.[7]

Parasites

Biomphalaria straminea is an intermediate host for Schistosoma mansoni and a vector of intestinal schistosomiasis. Schistosoma mansoni came to Neotropics from Africa in context of the slave trade.[8] Schistosoma mansoni was not able to infect Biomphalaria straminea previously and it has adapted to this host.[8]
