1. Molluscicidal effect of Euphorbia umbellata (Pax) Bruyns latex on Biomphalaria glabrata, Schistosoma mansoni host snail
ABSTRACT Euphorbia umbellata (Pax) Bruyns is an easily cultivated shrub, with occurrence in the tropical regions of the American and African continents. Chemical studies have revealed that the latex of this plant is rich in terpene compounds, which are highly toxic to snails Biomphalaria glabrata (Basommatophora: Planorbidae). The aim of this study was to ev

2. Persistência da transmissão de Schistosoma mansoni em localidade de Itariri, na região do Vale do Ribeira, São Paulo, Brasil / Persistent transmission of Schistosoma mansoni Itariri location in the Vale do Ribeira, Sao Paulo, Brazil.
Introdução A transmissão de esquistossomose é considerada um problema de saúde pública em várias regiões do Brasil, entre elas, a região do Vale do Ribeira, Estado de São Paulo. Em 2009, um censo coprológico com alunos de 6 a 14 anos na escola estadual do bairro de Ana Dias, no município de Itariri, detectou 34 casos de esquistossomose (16,8 por

4. Possible competitive displacement of planorbids by Melanoides tuberculata in Minas Gerais, Brazil
Several species of snails, including Pomacea haustrum, Marisa cornuarietis and Helisoma duryi, have been identified as probable competitors and/or predators of planorbid intermediate hosts of Schistosoma. During the last few years, studies carried out in the Caribbean region have shown reductions and even disappearances of populations of Biomphalaria glabrat

5. Invading freshwater snails and biological control in Martinique Island, French West Indies
Eight alien freshwater snail species were introduced into Martinique Island during the last 50 years. The introduced snails include four planorbids (Biomphalaria straminea, Helisoma duryi, Amerianna carinata and Gyraulus sp.), three thiarids (Melanoides tuberculata, M. amabilis and Tarebia granifera) and one ampullarid (Marisa cornuarietis). Four of these sp

6. Geographical distribution of Biomphalaria snails in the State of Minas Gerais, Brazil
Published and unpublished observations on geographical distribution of Biomphalaria snails in the State of Minas Gerais, Brazil, were compiled. This work is aimed at knowing the present occurrence of Biomphalaria species in this region, and at contributing to the elaboration of the planorbid chart of Minas Gerais. In malacological surveys, performed by sever

7. Identification of planorbids from Venezuela by polymerase chain reaction amplification and restriction fragment length polymorphism of internal transcriber spacer of the RNA ribosomal gene
Snails of the genus Biomphalaria from Venezuela were subjected to morphological assessment as well as polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) analysis. Morphological identification was carried out by comparison of characters of the shell and the male and female reproductive apparatus. The PCR-RFLP involved amplificat
