Electrophoretic analysis of a natural population of the ThaiParagonimus heterotremus and its genetic relationship to the three Japanese speciesP. miyazakii, P. ohirai andP. westermani

Abstract
A total of 18 enzymes (encoded by 20 loci) fromParagonimus heterotremus collected at a local area in Saraburi, Thailand, were electrophoretically compared with those from the three Japanese speciesP. ohirai, P. miyazakii andP. westermani using horizontal starchgel electrophoresis. Relative genetic distances between these species were quantified. The ThaiP. heterotremus was found to be most closely related toP. miyazaki and rather distantly related toP. westermani. On the other hand, among the three Japanese species, the closest relationship was observed betweenP. miyazakii andP. ohirai.
