Wildlife has been recognized that has important role as reservoir hosts of disease affecting both people and livestocks. However, information intestinal helminths of Korean water deer were limited. We obtained 20 feces from Korean water deers that were transferred to veterinary hospital in Chungbuk National University from May 2010 to June 2011. Parasite ova were collected using saturated zinc sulfate floatation method. Parasite eggs were examined and measured using light microscope. The identification of parasitic eggs was done by morphological characters. The overall infection rate of parasite was 85% (n=17). The eggs were observed as being Nematodirus spp. (n=14), strongyles egg (n=11), Capillaria spp. (n=9), Trichuris spp. (n=7), Eimeria spp. (n=4), Ogmocotyle spp. (n=3), and Strongyloides (n=1). Mixed infection rate was observed as being single 15% (n=3), double 20% (n=3), triple 15% (n=3), quadruple 30% (n=6), and quintuple 5% (n=1). The Ogmocotyle spp. was first reported in Korea.
