title: [Epizoological Survey On Infestation Rate Of Helminths In Korean Native Cattle]
abstract: The authors made a study on the species and distribution of helminths in Korean native cattle. The feces and internal organs from 1,755 heads were examined in slaughter plants of Taejon district. The results are summarized as follows. 1. Distribution and infestation rate of helminths among the collected samples are, Paramphistomum spp. 68.4%, Fasciola spp. 48%, Eurytrema spp. 23.5%, Moniezia spp. 8%, Dictyocaulus spp. 3.5%, Trichostrongylus spp. 12.4%, and other species 26.8%, respectively. 2. In 36.4% of ths cases, single infestation was seen and in 31.5%, 18.0%, and 14.0 % mixed infestation of double, triple, and quadruple or more species were seen, respectively. 3. Geographical analysis of infested helminths in the native cattle indicates: a. Among the trematoda order, Paramphistomum spp. and Fasciola spp. showed high rate of infestation throughout all districts of the country, especially Cheju island with a significant higher rate. Central district (Taejon) was higher in number of native cattle infested with Fasciola spp. than any other district of the country investigated. b. The rate of infestation with cestoda also showed to be higher in Cheju island than any other district of main land, but the rate of infestation with other nematoda showed no geographical difference.
