Electrophoregrams showing results of PCR of bacterial and digenean DNA from the same extracts obtained from single cercariae. (A) Results of amplification of digenean partial 28S gene from 26 single cercarial homogenates. (B) Results of screening the same 26 single cercarial homogenates for Neorickettsia DNA by nested PCR of partial 16S gene. Lanes with positive and negative controls are labeled.
