영남지방(嶺南地方) 축우(畜牛) 간질충(肝蛭蟲)의 감염율(感染率) 및 간질충(肝蛭蟲)의 형태(形態)에 관(關)하여

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 duct, 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.
