Abstract
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 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- antibodies and found that 182 of 585 (31.1%) samples were positive, and were found in 109 of 187 (58.3%) herds assessed.
摘要
是猪地方性肺炎的病原体，也是猪呼吸道疾病综合征的主要病因之一。大多数巴西商业猪场都呈该病原体阳性。然而，据我们所知，后院猪场中该病原体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后院猪场中该病原体的流行情况。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 ELISA 法检测血清中的抗抗体，发现 585 份样本中有 182 份（31.1%）为阳性，在所评估的 187 个猪群中有 109 个（58.3%）为阳性。
