| Outline of Final Research Achievements |
Parthenogenic Fasciola sp. came into existence to result from interspecific hybridyzation between Fasciola hepatica and Fasciola gigantica in China. Parthenogenic Fasciola sp. is divided into two distinct lineages (Fh and Fg lineages) of which maternal ancestors are F. hepatica and F. gigantica, respectively. Fh lineage is found in Japan, Korea and China, whereas Fg lineage widely occur in Vietnam, Thailand, Myanmar, Nepal, Bangladesh, eastern India and Philippines in addition to the three counties of Fh lineage. Domestic cattle was thought to have played an key role as a final host in spread of parthenogenic Fasciola sp. throughout Asian countries from China.
