Abstract:
Bulinus truncatus rohlfsi is a snail host of the human blood fluke Schistosoma haematobium. Observations on the dynamics of laboratory cultures of B. t. rohlfsi are presented from a series of experiments that investigated the effects of population density, pH, and oxygen concentration, and the inhibitory effects of old snail culture media. The data suggest that survival and fecundity are density dependent and that the cause of this effect is a fairly thermostable compound with a molecular weight <1000.

Abstract:
SUMMARYThe snail Bulinus nasutus 1214 possesses a potent haemagglutinin (end-point titre with human erythrocytes, 2−18) in its cell-free haemolymph which also binds to the miracidia (but not other larvae) of the incompatible parasite Schistosoma margrebowiei. We have purified a protein possessing this haemagglutinating property from the plasma of this snail. The native Mr of this protein was estimated by SDS polyacrylamide gel electrophoresis to be 210 kDa; under denaturing conditions in a 7.5% PAGE gel it ran as a major band of 135 kDa. Proteins of similar Mr were also found in the haemolymph

Abstract:
Freshwater snails of the genera Biomphalaria, Bulinus, and Oncomelania are intermediate hosts of schistosomes that cause human schistosomiasis, one of the most significant infectious neglected diseases in the world. Identification of freshwater snails is usually based on morphology and, potentially, DNA-based methods, but these have many drawbacks that hamper their use. MALDI-TOF MS has revolutionised clinical microbiology and has emerged in the medical entomology field. This study aims to evaluate MALDI-TOF MS profiling for the identification of both frozen and ethanol-stored snail species us

The plant was tested on uninfected B. pfeifferi and B. truncatus, the results showed that unfiltered extracts were found relatively more potent than filtered o

Abstract:
The transmission of some schistosome parasites is dependent on the planorbid snail hosts. Bulinus truncatus is important in urinary schistosomiasis epidemiology in Africa. Hence, there is a need to define the snails’ phylogeography. This study assessed the population genetic structure of B. truncatus from Giza and Sharkia (Egypt), Barakat (Sudan) and Madziwa, Shamva District (Zimbabwe) using mitochondrial cytochrome oxidase subunit 1 gene (COI) and internal transcribed spacer 1 (ITS 1) markers. COI was sequenced from 94 B. truncatus samples including 38 (Egypt), 36 (Sudan) and 20 (Zimbabwe). H

Les schistosomoses constituent encore un problème de santé publique au Cameroun. La forme urinaire due à S. Haematobium est la plus répandue et est transmise à l'homme par des mollusques hôtes intermédiaires dont les plus importants sont Bulinus truncatus et B. Globosus. Pour tenter d'expliquer la diversité observée dans le fonctionnement des foyers de schistosomoses urinaires, une étude de la structure génétique des populations de B. Truncatus et de B.

Abstract:
L'objectif de cette these est de comprendre l'evolution d'un polymorphisme sexuel tres particulier, l'aphallie, chez le gasteropode pulmone bulinus truncatus. Ce polymorphisme se caracterise par la coexistence de deux morphes sexuels dans les populations naturelles: des individus hermaphrodites normaux (euphalliques) et des individus depourvus d'organe copulateur male (aphalliques). Les deux morphes peuvent s'autofeconder. Mais, en allofecondation, les individus aphalliques ne peuvent jouer que le role de femelle. Ainsi, l'evolution de l'aphallie et de l'autofecondation sont intimement liees.
