Abstract

Researches in veterinary protozoology until the end of World War II were carried out entirely by Japanese workers such as Danagga, Yamada, Yuhoba and Isshiki. After the Korean war, investigations have been made by several Korean researchers such as Lee's, Son, Joen and Jang. The total species and genera of veterinary protozoa reported by authors up to date were 19 genera and 59 species except the commensal ciliates. Incidence of the protozoa were carried out for 4 years(1972-l975) by examining fecal samples and vaginal swabs in order to know the parasitic status of the domestic animals and poultry. The results are shown as followings. In dairy cattle: Entamoeba bovis 41.4 per cent , Eimeria spp. 5.6-15.0 per cent. In native cattle: Entamoeba bovis 47.6 per cent, Tritrichomonas foetus 8.5 per cent. In native horse: Eimeria sp. 10.0 per cent. In goat: Eimeria spp. 100 per cent. In swine: Entamoeba spp. 55.44 per cent, Eimeria spp. 20 per cent, Balantidium coli 66.58 per cent. In dog: Isospora bigemina(Large type) 8.7 per cent, Giardia canis 4.4 per cent. In cat: Isospora spp. 12.8 per cent. In hare: Entamoeba cuniculi 12.0 per cent, Eimeria spp. 20.0 per cent, Chilomastix cuniculi 12.0 per cent , Giardia cuniculi 4.0 per cent. In turkey: Eimeria spp. 33.3 per cent, Hexamita meleagriais 8.3 per cent. In chicken: Eimeria spp. 26.8 per cent. The main protozoan diseases of the domestic animals and poultry in Korea may be summarized from the data reported and surveyed as followings. Coccidiosis; poultry, hare, goat, cattle, swine. Theileriasis; cattle. Babesiasis; cattle, dog. Anaplasmosis; cattle, goat. Eperythrozoonosis; cattle, swine. Leucocytozoonosis; chicken. Histomoniasis; chicken. Toxoplasmosis; swine, cat. Balantidiasis; swine. Besnoitiosis; native cattle. Amoebiasis; swine, cattle. Sarcosporidiosis; Cattle, swine.
