O gênero Biomphalaria (Preston, 1910), da família Planorbidae, tem importância médica no Brasil, pois inclui três espécies suscetíveis ao trematódeo Schistosoma mansoni Sambon, 1907: Biomphalaria glabrata (Say, 1818), Biomphalaria tenagophila tenagophila (d'Orbigny, 1935) e Biomphalaria straminea...
Abstract INTRODUCTION: Ourinhos is a municipality located between the Pardo and Paranapanema rivers, and it has been characterized by the endemic transmission of schistosomiasis since 1952. We used geospatial analysis to identify areas prone to human schistosomiasis infections in Ourinhos. We studied th...
Information on areas colonized by snails that transmit Schistosoma mansoni is essential for planning schistosomiasis control measures. Therefore, the purpose of this study was to map the natural breeding sites of Biomphalaria spp. in the municipality of Peri Mirim, Maranhão, Br...
A nanotecnologia representa uma tendência chave na ciência e tecnologia do século XXI. As nanopartículas de óxido de zinco (NPs de ZnO) estão entre as mais utilizadas devido a sua capacidade de refletir, absrover e dispersar a radiação ultravioleta. A partir da sua larga utilização em fotoprote...
A esquistossomose é uma parasitose de veiculação hídrica causada por trematódeos do gênero Schistosoma, transmitida por caramujos planorbídeos do gênero Biomphalaria. O presente estudo teve por objetivo identificar e analisar os caramujos do gênero Biomphalaria encontrados em coleções hídrica...

Abstract INTRODUCTION: Schistosomiasis, caused by infection from Schistosoma mansoni, is a disease that represents an important public health problem for Brazil, especially for states in the Northeast region. Thus, the aim of this study is to present a new epidemiological profile for the disease in a m...
Abstract INTRODUCTION: Biomphalaria snails may display varying levels of susceptibility to Schistosoma mansoni infection. We have been developing an in vitro model to study the interaction between the snail and the parasite, using tissue-derived cell cultures from Biomphalaria. METHODS: The digestive g...

The aim of this work was to evaluate the potential of the essential oil (EO) from Ocotea pulchella leaves as an alternative in the control of schistosomiasis. It was tested O. pulchella EO nanoformulation to assess its activity against adult Biomphalaria glabrata, their spawning and Schistossoma mansoni...

BACKGROUND Biomphalaria glabrata snails are widely distributed in schistosomiasis endemic areas like America and Caribe, displaying high susceptibility to infection by Schistosoma mansoni. After the availability of B. glabrata genome and transcriptome data, studies focusing on genetic markers and small n...

Schistosomiasis is a parasitic disease caused by Schistosoma mansoni whose intermediate host is the snail of the genus Biomphalaria. This snail is geographically widespread, making the disease a serious public health problem. The purpose of this study was to analyze the growth, reproductive rates and mor...
