摘要

猪肺炎支原体是猪流行性肺炎的致病菌，也是猪呼吸道疾病综合症的主要病原体之一。巴西大多数商业养猪场对这种病原体呈阳性反应。然而，据我们所知，该病原体在散养猪场中的流行情况尚未得到描述。因此，我们旨在确定巴西巴拉那州散养猪场中肺炎霉形体的流行情况。2020 年 1 月至 3 月，我们从 187 个未接种疫苗的猪群中采集了 585 份血清样本。我们用间接酶联免疫吸附法检测血清中的抗猪肺疫病抗体，发现 585 份样本中有 182 份（31.1%）呈阳性，在 187 个接受评估的猪群中有 109 个（58.3%）呈阳性。

Detection of anti-Mycoplasma hyopneumoniae antibodies in backyard pigs in the state of Paraná, Brazil.

Mycoplasma hyopneumoniae is the causative bacterium of porcine enzootic pneumonia and one of the primary etiologic agents of the porcine respiratory disease complex. Most Brazilian commercial pig farms are positive for this pathogen. However, the prevalence of the pathogen in backyard pig farms has not been described, to our knowledge. Therefore, we aimed to determine the prevalence of M. hyopneumoniae in backyard pig farms in the state of Paraná, Brazil. In January-March 2020, we collected 585 serum samples from pigs in 187 non-vaccinated herds. We tested the sera with an indirect ELISA for anti-M. hyopneumoniae antibodies and found that 182 of 585 (31.1%) samples were positive, and were found in 109 of 187 (58.3%) herds assessed.
