Porcine cytomegalovirus (PCMV) is a recognized pathogen of domestic swine that is widely distributed around the world. PCMV is the etiological agent of inclusion body rhinitis and has also been associated with other diseases that cause substantial losses in swine production. Wild boar populations can act as reservoirs of numerous infectious agents that affect pig livestock, including PCMV. The aim of this work was to assess the circulation of this virus in free-living wild boars that inhabit Northeastern Patagonia (Buenos Aires and Río Negro Provinces), Argentina. Nested-PCR assays were conducted to evaluate the presence of PCMV in samples of tonsil tissue collected from 62 wild boar individuals. It was found that the overall rate of infection was about 56%, with significant higher values (almost 90%) in the age group corresponding to piglets (animals less than 6 months old). In addition, a seasonal variation was observed in the PCMV detection rate, with an increase during the transition from summer to autumn. In conclusion, this study confirmed that wild boars are major carriers and dispersal agents of PCMV in Northeastern Patagonia, which raises the necessity to evaluate the extent to which this virus affects local livestock production.

猪巨细胞病毒(PCMV)是公认的家猪病原体，广泛分布于世界各地。PCMV 是包涵体鼻炎的病原体，并且还与导致猪生产重大损失的其他疾病有关。野猪种群可以作为影响猪牲畜的多种传染性病原体的储存库，包括 PCMV。这项工作的目的是评估这种病毒在阿根廷巴塔哥尼亚东北部（布宜诺斯艾利斯和里奥内格罗省）自由生活的野猪中的传播情况。进行巢式 PCR 检测以评估从 62 只野猪个体收集的扁桃体组织样本中 PCMV 的存在。结果发现，总体感染率约为56%，在与仔猪（小于 6 个月大的动物）对应的年龄组中具有显着更高的值（几乎 90%）。此外，在从夏季到秋季的过渡期间，PCMV 检测率出现季节性变化。总之，这项研究证实，野猪是巴塔哥尼亚东北部 PCMV 的主要携带者和传播媒介，因此有必要评估这种病毒对当地畜牧生产的影响程度。
