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:

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.[6] Schistosoma mansoni was not able to infect Biomphalaria straminea previously and it has adapted to this host.[6]
