Fig. 1From: Molecular identification of Bulinus spp. intermediate host snails of Schistosoma spp. in crater lakes of western Uganda with implications for the transmission of the Schistosoma haematobium group parasitesSampling sites in the three crater lakes fields in Uganda and at the supra-regional scale. a Ndali-Kasenda crater lakes. b Bunyaruguru crater lakes. c Populations from East Africa. d Fort Portal crater lakes. Snail symbols indicate localities of Bulinus populations studied, whereas a star indicates when sampling did not yield a Bulinus population in the respective crater lake. Note that data for some populations used were retrieved from GenBank (see Table 1)Back to article page
