Abstract

Total 13 genera (28 species) of heterophyid flukes (family Heterophyidae) are known to cause human infections around the world; Acanthotrema, Apophallus, Ascocotyle, Centrocestus, Cryptocotyle, Haplorchis, Heterophyes, Heterophyopsis, Metagonimus, Procerovum, Pygidiopsis, Stellantchasmus, and Stictodora. Among them, 7 involving more than 2 species are Metagonimus, Heterophyes, Haplorchis, Centrocestus, Procerovum, Pygidiopsis, and Stictodora. They are contracted to humans by ingesting raw or improperly cooked freshwater or brackish water fish. In view of the wide geographical distribution and the large number of infected people around the world, Metagonimus, Heterophyes, and Haplorchis are the 3 major genera which are most highlighted in this review book. Species of the other 10 human-infecting genera are also briefly described. Heterophyids without human infections are given only by their names with literature background as potentially zoonotic species.
