The authors examined lung tissue samples collected from 140 pigs died presenting respiratory clinical symptoms. Pneumonia was observed in 97 cases (69%) with gross pathological, and in 135 cases (96%) with histological examination. PCV2 was the most frequent respiratory pathogen (49 cases, 35%), followed by Pasteurella multocida (41 cases, 29%), porcine reproductive and respiratory syndrome virus (10 cases, 7%), Streptococcus spp. (10 cases, 7%), swine influenza virus (4 cases, 3%), Actinobacillus pleuropneumoniae (4 cases, 3%), A. suis (2, 1.4%), Arcanobacterium pyogenes (1 case, 0.7%) and Bordetella bronchiseptica (1 case, 0.7%). Chlamydia was not detected. Single infection was found in 41 of the 74 cases (55%) with positive microbiological results, while co-infections of 2 to 4 pathogens were found in the remaining 33 cases(45%). Pathological lesions were suggestive only for cases with PCV2 and P. multocida infections. In conclusion, detailed pathological and microbiological examinations are necessary for the exact diagnosis of swine respiratory diseases.
