title: Comparison of isozyme patterns between Spirometra erinacei and Spirometra mansonoides by isoelectric focusing.
abstract: No differences were observed in the isozyme patterns of 4 enzymes examined between fresh samples stored at -80 C and samples stored at room temperature for 10 days after lyophilization, which supports the validity of comparing lyophilized samples to fresh frozen tissue. Mature proglottids as well as plerocercoids of Spirometra erinacei from Japan and Australia were indistinguishable by comparison of isozyme patterns after isoelectric focusing. The isozyme patterns of acid phosphatase, glucosephosphate isomerase (GPI), and mannosephosphate isomerase from plerocercoids of Spirometra mansonoides were distinctly different from those of plerocercoids of S. erinacei. The adenylate kinase isozyme patterns of the mature proglottids of S. mansonoides were also distinctly different from those of the mature proglottids and the plerocercoids of S. erinacei. The GPI isozyme pattern of the mature proglottids of S. mansonoides was also distinguishable from the GPI patterns of those of S. erinacei. These electrophoretic data suggest that the S. erinacei from Japan and Australia are closely related, if not identical, but that S. mansonoides is genetically distinct from S. erinacei.
