Zusammenfassung:This study was performed to investigate Mycoplasma (M) spp. infection status of dairy cow in South Korea. Among 8,485 bulk tank milk collected from dairy farms of the 5 areas, 26 samples (0.30%) were positive for Mycoplasma by direct culture method. The isolation rates of Mycoplasma spp. according to the areas were 0.51% in Kyonggi, 0.16% in Cholla, 0.23% in Gyoungsang, 0.12% in Chungchong, and 0.08% in Kangwon. In the species identification test by indirect immunoperoxidase test, 16 out of 26 isolates were identified as M bovis (61.53%), M bovigenitalium (23.07%), M californicum (7.69%), M alkalescens and Acholeplasma laidlawii (3.84%), respectively. The isolation rate of Mycoplasma spp. from 208 quarter milk samples in culling cows due to severe clinical mastitis was 3.0%. These Mycoplasma spp. were identified as M bovis (62.0%), M bovigenitalium (12.0%), M californicaum (12.0%), and M alkalescens (12.0%). This study shows that the bovine mammary gland infected by Mycoplasma spp. is present in some dairy farms and the routine culture test of bulk tank milk samples for Mycoplasma is needed for a high quality milk promotion services.
