Disease relevance of Bulinus

• The present study describes the action of the latex of Euphorbia splendens var. hislopii (E. milli) on species of the genus Bulinus and on Biomphalaria pfeifferi, intermediate hosts of schistosomiasis in Africa, and the Brazilian snails B. glabrata, B. tenagophila, and B. straminea, intermediate hosts of schistosomiasis in Brazil [1].
• Compared to aqueous extract, methanol extract showed the highest toxicity against all tested organisms with LC100-values of 25 p.p.m. for cercariae and the snail Biomphalaria glabrata and 1 p.p.m. for the snails Bulinus truncatus and B. natalensis [2].

High impact information on Bulinus

• Schistosome-infected Bulinus globosus, the snail vector of S haematobium in Malawi, were found at Cape Maclear and other locations along the lakeshore [3].
• Crystal structure of acetylcholine-binding protein from Bulinus truncatus reveals the conserved structural scaffold and sites of variation in nicotinic acetylcholine receptors [4].
• Moreover, when sections from infected snails (Biomphalaria, Bulinus and Lymnaea) were analysed by immunofluorescence using the same infection sera, only the tegument of the developing cercariae was recognized, but not the acetabular glands [5].
• Isoelectric focusing studies on enzyme variation between populations of the snail Bulinus senegalensis revealed that parasitic infections in the snails contributed additional bands of enzyme activity, particularly in the glucose phosphate isomerase (GPI) and malate dehydrogenase (MDH) systems [6].
• Encouragingly, several non-target aquatic organisms (larvae of Culex pipiens and Artemia salina and adult Gambusia affinis) and Drosophila melanogaster appeared largely unaffected by exposure to concentrations of the extract that kill S. haematobium cercariae and Bulinus truncatus [7].

Chemical compound and disease context of Bulinus

• The activities of catalase (H2O2-oxidoreductase EC 1.11.1.6)- and glutathione reductase (EC 1.6.4.2) as two important scavenger enzymes, were measured in tissue homogenates of Biomphalaria alexandrina and Bulinus truncatus, the snail vectors of Schistosomiasis [8].
• Control of snail hosts of bilharziasis in Egypt. 2. Effect of triphenyltin hydroxide (Du-Ter) on carbohydrate metabolism of the snails Biomphalaria alexandria and Bulinus tuncatus [9].

Biological context of Bulinus

• A polymerase chain reaction-based polymorphic assay procedure (RAPD) was used to study the genetic diversity of intermediate host snails within the genus Bulinus [10].

Associations of Bulinus with chemical compounds

• Dynamics of schistosoma haematobium infection in a Gambian community. II. The effect on transmission of the control of Bulinus senegalensis by the use of niclosamide [11].
• Survivors of Bulinus truncatus from one exposure to niclosamide (Bayluscide) were used to establish the next generation in a five generation long laboratory selection for increased tolerance to niclosamide [12].
• The emergence pattern of Schistosoma curassoni cercariae from Bulinus umbilicatus, whose adult worms parasitize bovine, caprine, and ovine ungulates in Niger, is of a circadian type with a mean emission time at 0855 hr +/- 1 hr 6 min, characteristic of the schistosome species parasitizing domestic or wild cattle [13].
• Two glutathione S-transferase isoenzymes purified from Bulinus truncatus (Gastropoda: Planorbidae) [14].
• Successive extraction of the 18 active samples with petroleum ether, ethanol and water showed that the petroleum ether extracts of only 4 samples were active against Bulinus truncatus; while the alcoholic extracts of 16 samples were found to be active against the same snail species [15].

Gene context of Bulinus

• We purified and characterized two major glutathione S-transferase isoenzymes (GST2 and GST3) from snail Bulinus truncatus (Mollusca, Gastropoda, Planorbidae) tissue [14].
• On the larval trematodes recovered from Bulinus truncatus in Assiut Governorate. Part II. Leptocercous and amphistome cercariae [16].
• Higher yield of clutches, eggs and cercariae were observed in the rich protein diet group, Bulinus and Biomphalaria Snail seem to be influenced by diet in the same way [17].
• Both species exhibited 2 population peaks/year, the peaks of Biomphalaria were in March-April & August in both study areas, while for Bulinus these peaks occurred in March-May and August in El-Manayef area and in May and March, respectively, in El-Morra area [18].

Analytical, diagnostic and therapeutic context of Bulinus

• Among 14 plants of Moroccan folk medicine tested for molluscicidal activity, ethyl acetate extract from Origanum compactum and hexane extracts from both Chenopodium ambrosioides and Ruta chalepensis were the most active (LC(90)=2.00, 2.23 and 2.23 mg l(-1), respectively) against the schistosomiasis-transmitting snail Bulinus truncatus [19].
