【 摘 要 】

References(19)To elucidate current status of fasciolosis and eurytremosis in beef cattle of Japan,inspection data of Tokyo Metropolitan Shibaura Slaughterhouse where beef cattle wereshipped from all over Japan were analyzed, and questionnaire to farmers was conducted toassess the relationship between recognition of the disease occurrence in one’s own farmand attention to the diseases. The occurrence of fasciolosis and eurytremosis in beefcattle gradually decreased from 18.6% to 0.06% and from 0.58% to 0.02% during the periodof 1964 to 2010, respectively. When the current data from 2009 to 2012 were analyzed, theoccurrence of fasciolosis was recognized in cattle produced and fattened all over Japan,indicating the disease was prevalent nationwide. While, 97.5% ofEurytrema infection were detected in cattle produced in Okinawa,Shimane and Kagoshima, indicating the disease was endemic in these regions. Higheroccurrence (>0.7%) of fasciolosis was observed in minor breeds, such as JapaneseShorthorn. Japanese Black showed 0.09% and 0.05% of occurrence for fasciolosis andeurytremosis, respectively, but F1 crossbred with Japanese Black showed lower occurrence(0.007% and 0.002%, respectively). No tendency of occurrence in the age of cattle atslaughter was recognized, indicating the infections may have occurred at the growing andearly fattening stage of cattle. The questionnaire survey revealed that farmersexperiencing fasciolosis had more knowledge about the disease, however, factors, such astesting parasite infections and use of anti-Fasciola dewormers, were notaffected by the recognition of occurrence.
