Additional file 1: Table S1. of Assessing S. mansoni prevalence in Biomphalaria snails in the Gombe ecosystem of western Tanzania: the importance of DNA sequence data for clarifying species identification

Summary of sample sizes of snails collected for experimental shedding (number of snails collected) and PCR, along with the numbers of individuals per site within each sampled village that shed parasites or showed presence of the 500Â bp band expected for S. mansoni and the 1000Â bp band identified as another trematode. Also indicated is the number of PCR samples for which the snail band did not amplify (no. of snails negative for snail band); these were excluded from calculations of percentages for PCR-positive results. The sampling date, the season of sample collection, the stream name, and location of the villages are also indicated. (XLSX 15Â kb)
