Lake Victoria is a well-known hot spot for intestinal schistosomiasis, caused by infection with the trematode Schistosoma mansoni . The snail intermediate hosts of this parasite are Biomphalaria snails, choanomphala being predominant host within Victoria. prevalence S. populations influenced both biotic and abiotic factors, including physical chemical characteristics their environment, incidence in human (and reservoir hosts) level genetic compatibility between host. Using molecular xenomonitoring, we measured B. along Kenyan, Tanzanian Ugandan shorelines related to (habitat type, water depth, turbulence, temperature, conductivity, total dissolved solids, salinity, pH level) ( abundance, diversity populations) factors lake. overall mean at was 9.3%, highest occurring on shoreline (13.1%), followed (8.2%) Kenyan (4.7%) shorelines. There significant difference abundance , solids major anion/cation concentrations A Spearman’s rank analysis found that had significant, positive relationship higher levels acidity, cation (Ca 2 + Mg ) concentrations. Additionally, observed sites correlated haplotype score compared without infection, though there no scores. Although our based upon an archival unique collection relationships uncovered useful eco-epidemiological comparisons schistosomiasis across future.
