To better understand the gastropod community dynamics of fresh water snails in Upper Victoria Nile (UVN), spatial and temporal abundance changes assemblage were assessed biannually from April 2006 to 2021 at three transects. Biannual abundances gastropoda obtained by a ponar grab examine their structure relation Bujagali Hydropower Project (BHP). The consisted nine speciesbelonging five familie...

Overall 10389 snails were collected from four study areas of Punjab from November 2005 to October2006. The highest prevalence (38%) was found for Indoplanorbis followed by Physa (17%), Bellamaya(10.3%), Gyraulus (10%), Lymnaea (9.2%), Oncomelania (9%) and the lowest was found for Bulinus (6.7%).Only Indoplanorbis snails were found to be positive for Schistosoma bovis cercaria. Correlation betwe...

S. haematobium was first discovered in Sierra Leone in 1909 [1,2], and S. mansoni was later discovered in 1934 in the north of the country [1]. Recovered snail samples included both Bulinus globosus and Biomphalaria pfeifferi [1]. Peak transmission of schistosomiasis takes place at the beginning of the dry season, when water levels and habitat conditions are most suitable for snail hosts [1]. A...

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. The comparison of this cercarial emergence pattern with those of the other 3 sympa...

The genetic population structures of the freshwater snail Bulinus globosus and its trematode parasite Schistosoma haematobium from 8 river sites in the Zimbabwean highveld were compared using randomly amplified DNA (RAPD) markers. There was significant variability between snail populations collected at different sites, but schistosome populations only showed differentiation at a wider geographi...
