Biological control of the snail hosts of Schistosoma mansoni in the Caribbean area using Thiara spp.

Levantamento malacológico e mapeamento das áreas de risco para transmissão da esquistossomose mansoni no Município de Mariana, Minas Gerais, Brasil

“…MCCULLOUGH, 1989). No Brasil, foi citado pela primeira vez em São Paulo por Vaz e colaboradores (1986), que ressaltaram o papel desse molusco como hospedeiro intermediário de Clonorchis sinensis, e a espécie foi encontrada no Rio de Janeiro e em Minas Gerais, albergando larvas de trematódeos (BOAVENTURA et al, 2002;CARNEIRO et al, 2004;BOGÉA;CORDEIRO;GOUVEIA, 2005).…”

Control of Schistosomiasis

“…The South American snail, Marisa (Madsen, 1981), a number of field trials were either inconclusive or unsuccessful (Jordan, 1985). Pointer et al (1989) have reported on the use of the parthenogenetic snails, Thiara granifera and T. (Melanoides) tuberculara to eliminate the intermediate host of S mansoni-B. glabrata in the Carribean area.…”

Possible competitive displacement of planorbids by Melanoides tuberculata in Minas Gerais, Brazil

“…The use of molluscs in the biological control of the intermediate hosts of Schistosoma was stimulated in 1956 with the publication of the first studies involving the ampullarid Marisa cornuarietis (L.) in Puerto Rico (Chernin et al 1956). Since then, various other molluscs including Helisoma duryi (Wetherby, 1879); Bulinus tropicus (Krauss, 1848) (Pointier & McCullough 1989, Pointier et al 1991, Pointier & Guyard 1992, Pointier 1993, Pointier & Giboda 1999. However, the impact of M. tuberculata is varies according to the type of habitat.…”
