Evidence for host allozymes present on electrophoretic gels of trematode parasites (Digenea: Plagiorchiiformes).
An allozyme analysis of trematode species Glypthelmins californiensis, Glypthelmins quieta, Glypthelmins pennsylvaniensis, Glypthelmins hyloreus, and Haplometrana intestinalis from hosts Rana aurora, Rana clamitans, Hyla crucifer, Pseudacris triseriata, and Rana pretiosa, using starch gel electrophoresis, revealed allozymes for glucose-phosphate isomerase, lactate dehydrogenase, malate dehydrogenase, and isocitrate dehydrogenase that were similar in electrophoretic mobility to host tissue controls. Host allozymes were present on gels for only a fraction of the individual parasite samples examined and could be differentiated from parasite allozymes using host tissue controls. Based on these findings, it is suggested that host samples be included on each electrophoretic gel in genetic studies of parasites to reduce the likelihood of errors due to host enzyme contamination of parasite samples.
