Interaction of Biomphalaria cells in primary cultures with Schistosoma mansoni sporocysts [PDF]

Revista da Sociedade Brasileira de Medicina Tropical, 2020
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 ...

Prevalence of Schistosoma mansoni and S. haematobium in Snail Intermediate Hosts in Africa: A Systematic Review and Meta‐analysis

Journal of Tropical Medicine, Volume 2020, Issue 1, 2020., 2020
Background. Schistosomiasis is caused by Schistosoma mansoni and S. haematobium in Africa. These schistosome parasites use freshwater snail intermediate hosts to complete their lifecycle. Varied prevalence rates of these parasites in the snail intermediate hosts were reported from several African countries, but there were no summarized data for ...

Resistance of Biomphalaria alexandrina to Schistosoma mansoni and Bulinus truncatus to Schistosoma haematobium Correlates with Unsaturated Fatty Acid Levels in the Snail Soft Tissue

Journal of Parasitology Research, Volume 2020, Issue 1, 2020., 2020
Only a fraction of the Biomphalaria and Bulinus snail community shows patent infection with schistosomes despite continuous exposure to the parasite, indicating that a substantial proportion of snails may resist infection. Accordingly, exterminating the schistosome intermediate snail hosts in transmission foci in habitats that may extend to kilometres ...

ITS2 variability of Biomphalaria (Mollusca, Planorbidae) species from the Paranapanema Valley (São Paulo State, Brazil): diversity patterns, population structure, and phylogenetic relationships

Genetics and Molecular Biology, 2007
The ribosomal DNA internal transcribed spacer 2 (ITS2) has been shown to be a useful genetic marker for species identification and phylogenetic reconstruction in the genus of freshwater snails Biomphalaria (Preston 1910).

Cercariae (Digenea: Strigeidae, Diplostomidae) in Biomphalaria straminea (Planorbidae) from a rice field in Northeastern Argentina [PDF]

, 2017
The rice fields can provide habitats for many species of aquatic invertebrates, as insects, molluscs, crustaceans; and vertebrates, as fish, amphibians, reptiles and birds, which may act as hosts in the life cycles of digenean parasites. In this context,
