Although bovine respiratory syncytial virus (BRSV) infection has been reported in cattle in Argentina, it has not been associated with pneumonia in Argentina. We report here 5 cases of bovine pneumonia associated with BRSV. Autopsies were performed on 35 beef cattle with gross and/or microscopic lesions of pneumonia from 3 commercial feedlots. Lung samples in 5 of 35 animals were BRSV-positive by reverse-transcription nested PCR. The lungs of 2 of these 5 animals were coinfected with , and 1 with bovine viral diarrhea virus 1. Microscopically, the lungs of 3 of the 5 BRSV PCR-positive animals had fibrinosuppurative bronchopneumonia, with or without pleuritis; 2 of the 5 had interstitial pneumonia. We conclude that BRSV is part of the bovine respiratory disease complex in Argentina.
虽然在阿根廷的牛群中已经报告了牛呼吸道合胞体病毒（BRSV）感染，但它与阿根廷的肺炎无关。我们在这里报告了 5 例与 BRSV 相关的牛肺炎病例。对来自 3 个商业饲养场的 35 头具有肺炎的大体和/或显微镜病变的肉牛进行了解剖。在 35 个动物中有 5 个的肺样本通过反转录巢式 PCR 呈 BRSV 阳性。在这 5 个动物中的 2 个与 ，并且 1 个与牛病毒性腹泻病毒 1 共同感染。显微镜下，在 5 个 BRSV PCR 阳性动物中的 3 个具有纤维素性化脓性支气管肺炎，有或没有胸膜炎；其中 2 个具有间质性肺炎。我们得出结论，BRSV 是阿根廷牛呼吸道疾病综合症状的一部分。
