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%.
对来自挪威东南部9个选定猪群的855头屠宰体重猪的肺部大体病变的患病率和病理形态学进行了研究。在84%的猪肺中发现了肺炎或胸膜炎病变,受影响最小的猪群为37%,受影响最大的猪群为97%。在70%的猪肺中发现了提示原发性猪肺炎支原体感染的支气管肺炎,各猪群的比例从9%到82%不等。个体猪肺中支气管肺炎病变的比例从0到69%不等,平均为7.8%。在29%的猪肺中发现了提示胸膜肺炎放线杆菌(嗜血杆菌)感染的胸膜肺炎,受影响最小的猪群为0,受影响最大的猪群为58%。在41%的猪肺中发现了弥漫性胸膜炎,患病率从4%到63%不等。
