From April to May 1967 3,275 Korean native cattle slaughtered at Taegu public slaughter house were investigated for infection rate of faciola and 222 adult fasciola species taken from the bile ducts of the patients were examined for morphological study.
The results were as follows:
1. Among 3,275 Cattle 1,099 Cattle (32.5%) were infected with fasciola species.
2. Seasonal changes of infection rate were 34.7% (Winter), 33.2%(Spring), 30.9%(fall) and 29.1% (Summer).
3. Three different species(large, small and intermediate type) of fasciola were detected from the patients. These large, small and intermediate types were identified more phologically with fasciola gigantica, fasciola hepatical and fasciold indica respectivelly.
Distribution of these three kinds were 52.4%(intetmediate type), 28.4%(Small type) and 19.0 % (large type).
