Table. 2 Snail abundance and trematode infections per site. All snail species are listed per site along with the number of specimens collected (Sampled), the number of snails that shed cercariae in the shedding experiment (Shedding), the number of snails for which DNA was extracted for diagnostic multiplex PCRs (Tested), the number of samples that tested positive for a trematode infection (Trematoda inf.), and how many of those trematode infections had a Fasciola nyanzae (F. nyanzae inf.), Schistosoma edwardiense (S. edwardiense inf.), or Schistosoma haematobium infection (S. haematobium inf.). For Kariba sites, the number between brackets refers to exact sample location adopted from Carolus et al. [5]. High-resolution pictures of each snail morphotype are shown in Fig. 5
