Table 2 Fly counts per genus and trapping location used in the molecular survey for filarioid nematodes. Trapping locations correspond to the locations detailed in Fig. 1. Number of flies that were PCR-positive for E. schneideri are listed first, followed by the total fly count. Prevalence values (% PCR-positive for E. schneideri) are listed in parentheses
