Biomphalaria glabrata no Estado do Piauí

Abstract

The occurrence of Biomphalaria glabrata is recorded for the first time in the state of Piaui, where it was collected from several breeding places in the city of Parnaíba. Examination of 694 specimens showed that a part of them were infected with trematodes other than Schistosomatidae. So far no autochthonous cases of schistosomiasis have been identified in the city. The presence of B. glabrata in Parnaíba extends by 20 km eastward its range on the Northern Coastal Region of the Great Northeastern Region of Brazil, where it had been found as far as Araioses, on the eastern extreme of the state of Maranhão.

Malacofauna of lotic environments in the Northeast and Brazilian semiarid region: current knowledge and new records

“…In the state of Piauí it has been registered in 66 municipalities (Carvalho et al 2008, Silva et al 2020b. Despite the existence of records of B. glabrata in the state (Paraense & Araujo 1984, Carvalho et al 2008, there are no reports of co-occurrence with B. straminea, according already been reported by Guimarães et al (2009) for other water bodies in the semiarid. Due to the difference in the susceptibility to S. mansoni infection already observed between these species (Dias et al 1987), it is relevant to study the distribution, taxonomy, and ecology of this genus across the state.…”
