The present study was conducted to investigate the prevalence of Mycoplasma spp. in cows and pigs with pneumonic lung lesions in Gyeonggi province in 2017. One hundred ninety two and 257 lung tissues were collected from slaughtered cows and pigs with pneumonic lesions, respectively, and examined for the presence of Mycoplasma spp. by a genus specific PCR. Among the examined animals, 147 cows (76.5%) and 203 pigs (80.9%) were found to be infected with Mycoplasma spp.. The infected tissues were further examined to identify the specific species of Mycoplasma using species specific PCRs. The only identified species in cows was M. agalactiae which was detected from 16 cows (8.3%), whereas M. dispar, M. bovis, and M. bovirhinis were not detected. In pigs, M. hyopneumoniae was detected from 74 pigs (28.8%) and M. hyorhinis from 13 pigs (5.1%). M. hyosynoviae was not detected. Taken together, the current study indicates Mycoplasma spp. are commonly associated with lung infection in cows and pigs in Korea. Further studies are needed to evaluate the impact of Mycoplasma infection on the development of lung diseases in farm animals.
