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.

D型流感病毒（IDV）被认为与牛呼吸道疾病（BRD）有关。根据血清阳性率研究或从临床样本中分离出来，已在几大洲和几种动物物种（包括牛，猪，骆驼，马和山羊）中发现了这种病毒。我们使用间接内部ELISA来检测阿根廷拉潘帕省116个农场的165个公牛血清样品中的抗IDV抗体。116个农场中有八十五个（73％）的农场至少有1只阳性动物，而165个农场中有112个（68％）的样品为阳性。血清阳性样本的比例没有明显差异，具体取决于所采集样品的地理区域。我们的结果表明IDV感染是拉潘帕地区的地方病；IDV在阿根廷的临床重要性仍有待研究。
