[Species characterization of the lung fluke Paragonimus ecuadoriensis by isoenzyme -electrophoresis (author's transl)].

Whole body lysates of 35 adult lung flukes (25 Paragonimus ecuadoriensis, 2 P. africanus, 8 P. uterobilateralis) were electrophorized on thin-layer starch gel. Specific staining was performed for the isoenzymes of the following three enzymes: alanine aminotransferase (ALAT), peptidase 1 (PEP) and malate dehydrogenase (ME) (decarboxylating) (NADP). Two enzymes showed polymorphism and proved to be useful for intra- and interspecific comparison. The individuals of P. ecuadoriensis showed homogeneity and differed remarkably from two other Paragonimus species examined as controls.
