Relationships between macroscopic lesions and Polymerase Chain Reaction (PCR) detection of Mycoplasma hyopneumoniae (Mhp), Pasteurella multocida (Pm), Actinobacillus pleuropneumoniae (App), Haemophilus parasuis (Hps) and Streptococcus suis (Ssuis) of the lungs of 3731 slaughter pigs from 125 herds were assessed in France. Pneumonia and pleuritis were the most frequent lesions (69.3% and 15% of the lungs, respectively). Mhp, Pm, App, Ssuis and Hps were detected in 69.3%, 36.9%, 20.7%, 6.4% and 0.99% of the lungs, respectively. Mhp and Pm were associated with pneumonia at both the pig and herd levels. Pleuritis was not associated with any pathogen at the pig level, but was associated with a high percentage of pigs PCR-positive for App at the herd level. Measures focused on control of Mhp, Pm and App should significantly reduce the occurrence of both pneumonia and pleuritis.
在法国，评估了来自 125 个畜群的 3731 头屠宰猪肺部的支原体肺炎（Mhp）、多杀性巴氏杆菌（Pm）、胸膜肺炎放线杆菌（App）、副猪嗜血杆菌（Hps）和猪链球菌（Ssuis）的宏观病变与聚合酶链反应（PCR）检测之间的关系。肺炎和胸膜炎是最常见的病变（肺部分别为 69.3%和 15%）。Mhp、Pm、App、Ssuis 和 Hps 在肺部的检出率分别为 69.3%、36.9%、20.7%、6.4%和 0.99%。在猪和畜群水平上，Mhp 和 Pm 与肺炎相关。在猪水平上，胸膜炎与任何病原体均无关联，但与畜群水平上 App 阳性猪的比例较高相关。针对 Mhp、Pm 和 App 的控制措施应能显著降低肺炎和胸膜炎的发生。
