Four dead wild racoons found in Chonnam province were examined parasitologically, pathologically and bacteriologically. Using standard flotation technique with feces many number of ancylostoma eggs which were oval in shape and $60-70{ imes}35-45 {mu}m$ in size were detected. Grossly, severe anemia, multiple congestion and consolidation of lung and catarrhal exudate in small intestine were observed. One of racoons had multifocal white to yellow nodules in the liver. Histopathologically, ancylostoma larvas were found in intestinal lumen. Some of them penetrated and attached to intestinal mucosa. Lungs revealed multiple severe fibrinopurulent pneumonia in which bacterial colonies were scattered. Liver had multiple microabscesses containing peripheral bacterial colony. By Gram stain using paraffin sections of liver and lung, bacterial colony was Gram negative. Isolated bacteria from lung and liver was Gram negative rod. This bacteria was identical with Escherichia coli by biochemical tests. From these results, ancylostomiasis caused severe problems in Korean wild racoons. This is the first report about ancylostomiasis in wild racoons in Korea.
