Influenza D virus (IDV) is considered a new agent involved in bovine respiratory disease (BRD). Based on seroprevalence studies or isolation from clinical samples, this virus has been detected on several continents and in several animal species, including cattle, pigs, camel, horses, and goats. We used an indirect in-house ELISA to detect anti-IDV antibodies in 165 serum samples from bulls on 116 farms in the province of La Pampa, Argentina. Eighty-five of 116 (73%) farms had at least 1 positive animal, and 112 of 165 (68%) of the analyzed samples were positive. There were no significant differences in the proportion of seropositive samples depending on the geographic region in which the samples were taken. Our results suggest that IDV infection is endemic in La Pampa; the clinical importance of IDV in Argentina remains to be investigated.
丁型流感病毒（IDV）被认为是一种与牛呼吸道疾病（BRD）有关的新型病原体。基于血清流行率研究或从临床样本中分离出该病毒，已在几大洲以及包括牛、猪、骆驼、马和山羊在内的几种动物物种中检测到这种病毒。我们使用一种间接的内部ELISA方法，对来自阿根廷拉潘帕省116个农场的165份公牛血清样本中的抗IDV抗体进行检测。116个农场中有85个（73%）至少有1头阳性动物，165份分析样本中有112份（68%）呈阳性。根据采集样本的地理区域不同，血清阳性样本比例没有显著差异。我们的结果表明，IDV感染在拉潘帕省呈地方流行；IDV在阿根廷的临床重要性仍有待研究。
