From December 1995 to July 1997, a total of 546 Korean indigenous goats were examined for the presence of internal parasites by parenchymal organs and fecal examinations. Four hundreds seventy eight(87.5%) of the goats were infected with 4 classes and 12 parasitic species. The nematodes were Haemonchus contortus(57.5%), Oesophagostomun venulosum (52.6%), Strongyloides papillosus(48.4%), Ostertagia sp(28.4%), Trichostrongylus colubriformis(17.0%), and Trichuris ovis(13.2%). The trematodes were Paramphistomum sp(17.6%), Fasciola hepatica(15.4%), and Eurytrema Pancreaticum (8.8%). The cestode was Moniezia expansa(16.7%), and the protozoa were Eimeria sp(74.9%) and Toxoplasma gondii(8.6%). The incidence of single or mixed infections among 12 parasitic species were one species infection (6.2%), 2 species(11.5%), 3 species(19.6%), 4 species(24.9%), 5 species(17.8%), 6 species(5.9 %), and 7 species(1.6), respectively. The level of infection according to the age was considerably higher under one year(97.2%) than between one and two years(89.7%), and over two years(69.3%) Among 12 parasites, seasonal pattern was remarkably observed. Most paracites were detected at the highest level in the Winter, whereas Strongyloides papillosus and Paramphistomum sp were in the Spring, and Ostertagia sp and Fasciola hepatica were in the Autumn. Infection rates of Anaplasma sp were 8.6% of 210 goats by blood smear method, and 51.0% by complement fixation test.
