Miocene genus Kosovia was synonymized Bulinus in 2017.. Distribution. Snails were collected from their habitats and conserved in 70% ethanol until genetic analyses. Hence, there is a need to define the snails’ phylogeography. "The discovery of Bulinus (Pulmonata: Planorbidae) in a Miocene palaeolake in the Balkan Peninsula", http://www.marinespecies.org/aphia.php?p=taxdetails&id=224352, "Molecular characterization of freshwater snails in the genus Bulinus: A role for barcodes?". Since 1990, diploid Bulinus sp. Several samples have been … Physa truncatus Audouin, 1827 (Espèce CD_NOM = 904302) Références bibliographiques Bulinus truncatus (Audouin, 1827) : Falkner et al. 123 … Sci., 25: 37-60. The shell of species in the genus Bulinus is sinistral. [8], This genus has not yet become established in the USA, but it is considered to represent a potentially serious threat as a pest, an invasive species which could negatively affect agriculture, natural ecosystems, human health or commerce. Preston and V.R. [4], These snails are widespread in Africa including Madagascar[7] and the Middle East. distribution Bulinus truncatus in Abeokuta, Ogun State. 1000 Site Dl ! snails collected, 30 (1.9%) B. globosus were shedding morphologically identified schistosomes. High levels of genetic diversity were detected at all loci in the seven studied species, with clear segregation between individuals and appearance of different haplotypes, even within same species from the same locality. morphology, according to the simplified key of Brown and Kristensen (1991). Bulinus truncatus snails were initially identified based on shell morphology using the field identification key of Kristensen (Kristensen and Christensen, 1989), but see also the recent review of Lofty and Lofty (Lotfy and Lotfy, 2015).The samples were collected without chronometry from their habitats by two researchers and subsequently conserved in 70% ethanol. [5], This genus is medically important because several species of Bulinus function as intermediate hosts for the schistosomiasis blood fluke. (2002) [Statut pour la France métropolitaine] Falkner, G., Ripken, T. E. J. Therefore it has been suggested that this species be given top national quarantine significance in the USA.[9]. Appleton C., Lange C. N., Kristensen T. K., Stensgaard A-S. & Van Damme D. (2009). Accessed through: World Register of Marine Species at: Cowie R. H., Dillon R. T., Robinson D. G. & Smith J. W. (2009). Freshwater snails collected in central Namibia, south-western Africa, from 15 populations belonging to the Bulinus truncatus/tropicus complex (Planorbidae) are characterised in respect of their chromosome number, morphology, egg proteins and enzymes. Among the 1570 Bulinus spp. Cas particulier d'absence liée à une disparition avérée depuis moins d'un demi-siècle (les disparitions anciennes sont traitées comme « absence probable ou certaine »). Southgate ... morphology of the schistosome mira- cidium and subsequent intramolluscan larval stages.

Bulinus truncatus is important in urinary schistosomiasis epidemiology in Africa. Snails species belonging to the genus Bulinus (Planorbidae) serve as intermediate host for flukes belonging to the genus Schistosoma (Digenea, Platyhelminthes). Freshwater snails collected in central Namibia, south-western Africa, from 15 populations belonging to the Bulinus truncatus/tropicus complex (Planorbidae) are characterised in respect of their chromosome number, morphology, egg proteins and enzymes. 5. Each snail found ... Bulinus truncatus (E) and Bu. Bulinus est un genre composé de 37 espèces de petits escargots dulçaquicoles appartenant à la famille des Planorbidés.

This genus has not yet become established in the USA, but it is considered to represent a potentially serious threat as a pest, an invasive species which could negatively affect agriculture, natural ecosystems, human health or commerce. 1996, 18 p. ; ref : 2 p. Report number ENV-SRAE - 94019 Scientific dom Sources des 3 jeux de données. It was further examined for cercariae shedding. Despite its importance in the transmission of these parasites, the evolutionary history of this genus is still obscure. shell morphology. In Bulinus as in other Planorbidae the basic haploid chromosome number is 18 and B. tropicus belongs to a group of diploid forms (2n=36) distributed predominately in southern Africa. Studies of the relationships between Schistosoma and their intermediate hosts. Although, they are known to be widely distributed throughout Nigeria, there is the need for precise species identification to help vector control initiatives. Pour les espèces migratrices, la pr&easence indiqu&eae concerne les zones de reproduction. Today, this entire system is more generally referred to as the Bulinus truncatus/tropicus complex, with B. tropicus representing diploids from South Africa and B. truncatus comprising tetraploids from Egypt (Goldman et al., 1983). MolluscaBase eds. The cox1 region showed much more variation than the ribosomal markers within Bulinus sequences. Bulinus truncatus is widespread in northern Africa and reaches its southern range limit in Malawi, where it has been reported previously from 2 widely separated localities.
