The objective of this study was to determine the prevalence of pneumonic bacteria in lungs and nasal swabs of cattle with respiratory diseases. From 95 pneumonic lungs of slaughtered cattle, 41 (43.2%) positive lungs were yielded with 54 pneumonic bacteria, which corresponded to P. multocida (n = 34), A. pyogenes (n = 14) and P. haemolytica (n = 6). One-hundred sixty seven pneumonic bacteria were isolated from 195 nasal swabs in calves, 64.7% (108 isolates) belonged to P. multocida, 16.2% to A. pyogenes, 13.8% to P. haemolytica and 5.4% to H. somnus.
