Abstract: Pasteurella multocida is considered a important pathogens of swine respiratory system, causing progressive atrophic rhinitis, septicemia and pneumonia in pigs. The aim of this study is to quantify Pasteurella multocida in lungs of slaughtered pigs with and without pneumonia by qPCR technique and evaluate the interactions between bacteria and viruses by analyzing the association and the correlation between them using qPCR, microbiological and histopathological examinations of the lungs. Of the 109 samples collected, 61 samples showed no macroscopic lesions and 48 samples with macroscopic lesions. A total of 45.8% (22/48) of lung lesion group and 4.9% (3/61) of the group without lesions were positive for P. multocida isolation, being the only significant association with the lesion and control groups (p
