Non-specific esterase isoenzymes of adult schistosomes from the hippopotamus (Hippopotamus amphibius).

Extracts of adult schistosomes collected from Hippopotamus amphibius in the Kruger National Park gave alpha naphthyl acetate isoenzyme patterns after polyacrylamide gel electrophoresis that did not correspond with those of either Schistosoma mansoni or S. rodhaini.
