Abstract

A field survey of fascioliasis of Korean native cattle raising and raised in specialized commercial breeding farms and local farms in Kangwon province using both intradermal test and sedimentation technique for feces was carried out from November to December, 1996. Fecal samples were taken from fascioliasis positive cattle by the intradermal test for the fecal examination. Liver tissues were randomly collected from an abattoir for histopathological examination of liver fluke infection in cattle. The results are as follows. 1. By the intradermal test for a total of 211 cattle raising in both Wonju and Wheongsung, Kangwon province, 60 heads(28.4%) showed positive reaction. Among 60 positive cattle, eggs of Fasciola hepatica were found from 51 heads(85.0%) by sedimentation technique. 2. According to the cattle raising areas, the positive rates by the intradermal test were 26.7%(20 out of 75 heads) in Wonju and 29.4%(40 out of 136 heads) in Wheongsung. 3. According to the age of cattle examined, the positive rates by the intradermal test in 1~3, 4~6 and 7~10 years old were 11.7%(7 out of 100 heads), 68.3%(41 out of 93 heads) and 20.0%(12 out of 18 heads), respectively. 4. The overall infection rates of fluke larvae from the slaughtered cattle at an abattoir in Wonju was 24.7%(37 out of 150 heads). In histopathology, liver lesions were observed such as inflammation with infiltration of eosinophils, polymorphonuclear cells, mononuclear cells and multinucleated giant cells, proliferation of connective tissues, calcification and abscess formation.
