Abstract

The prevalence and pathomorphology of gross lung lesions were studied in 855 slaughter weight pigs from 9 selected herds in south-eastern Norway. Pneumonic or pleuritic lesions were found in 84 % of the lungs, ranging from 37 % in the least affected herd to 97 % in the one most affected. Bronchopneumonia indicative of a primary Mycoplasma hyopneumoniae infection was found in 70 % of the lungs, ranging from 9 % to 82 % in the individual herds. The amount of bronchopneumonic lesions in individual lungs ranged from 0 to 69 %, with an average of 7.8 %. Pleuropneumonia indicative of Actinobacillus (Haemophilus) pleuropneumoniae infection was found in 29 % of the lungs ranging from 0 in the least affected herd to 58 % in the most affected. Diffuse pleuritis was found in 41 % of the lungs and the prevalence ranged from 4 % to 63 %.

Keywords: bronchopneumonia, pleuropneumonia, pathomorphology
