Web. Snails belonging to the genus Biomphalaria Preston, 1910 are widespread in Africa and South America, where they are intermediate hosts for Schistosoma mansoni, which causes intestinal schistosomiasis.Approximately 30 Biomphalaria species occur worldwide, with about 12 species restricted to Africa. Also, snails’ exposure to LC 25 of Artemether demonstrated a decreased glycogen content in hermaphrodite gland tissues while it increased in the haemolymph. Es wurden vergleichende Untersuchungen zur mollusciziden Aktivität derBacillus thuringiensis-Präparate Thuricide, SAN 401, SAN 403 und SAN 415 auf die als Zwischenwirt des Bilharziose-Saugwurms des Menschen,Schistosoma mansoni, fungierende SchneckeBiomphalaria alexandrina in Saudi-Arabien durchgeführt.. The African species of Biomphalaria appeared as a result of the relatively recent west-to-east trans-Atlantic dispersal of the Biomphalaria glabrata-like taxon. Schistosomiasis is considered the second most important parasitic disease in the world, ranking next to malaria (Combes 1990). Major changes in the epithelial region of the digestive gland were also observed by Bakry (2009), who reported that infection of snails with B. alexandrina with S. mansoni miracidia caused … Medical Information Search.

According to morphology, the most infected Biomphalaria species which shed S. mansoni cercariae were Biomphalaria stanleyi and Biomphalaria choanomphala; thus their control could significantly reduce S. mansoni transmission.

Habib Detailed studies were made on the morphology of larval trematodes (cercariae and metacercariae), and on that, of nematodes recovered from snails in order to complcto the data available on this group of helminths in Egypt. The African species have been placed in four species groups by Mandahl-Barth … Such populations must then be restricted to waters with some minimum dissolved oxygen – perhaps flowing, perhaps deeper, presumably cooler. Earlier authors studying this subject were, e. g., Sonsino (1892), Azim (1930), Kuntz (1953), Nagaty et al. Biological and hematological responses of Biomphalaria alexandrina to mycobiosynthsis silver nanoparticles. The three known sympatric Biomphalaria species that occur in Lake Albert; B. choanomphala, B. stanleyi and B. sudanica, were studied using both molecular (COI, 16S and ITS) and shell morphometric data.
