Porcine Kobuvirus (PKV) infection is very common in pigs throughout the world. Since it has never been investigated in Serbia, to contribute to the knowledge of Porcine Kobuvirus, its role, and distribution, we tested 200 samples from domestic pigs and wild boars. From domestic pigs, 10 fecal, 22 spleen and 68 serum samples, and 100 spleen samples from wild boars were tested. The virus prevalence determined by real-time RT-PCR in domestic pigs was 22% and in wild boars 6%. The phylogenetic analysis of 3D region revealed that Serbian strains are closest related to the Hungarian strain from wild boar from 2011. This is the first report on PKV in Serbia in domestic pigs and wild boars, implying its wide circulation. Although the infection could not be directly related to any clinical manifestation, the frequency of virus found in feces suggests viral affinity to the gastrointestinal tract. However, due to the rather ubiquitous presence of PKV, the clinical and pathological assessment have to be considered when PKV infection is diagnosed.
猪博卡病毒（PKV）感染在世界各地的猪中非常普遍。由于塞尔维亚从未对此进行过调查，为了增进对猪博卡病毒的了解，包括其作用和分布，我们检测了 200 份来自家猪和野猪的样本。从家猪中检测了 10 份粪便、22 份脾脏和 68 份血清样本，以及 100 份野猪脾脏样本。实时 RT-PCR 检测到家猪的病毒流行率为 22%，野猪为 6%。3D 区的系统进化分析表明，塞尔维亚毒株与 2011 年来自野猪的匈牙利毒株最为密切相关。这是首次在塞尔维亚的家猪和野猪中报告 PKV，表明其广泛传播。尽管感染不能直接与任何临床表现相关，但粪便中发现病毒的频率表明病毒对胃肠道有亲和力。然而，由于 PKV 广泛存在，在诊断 PKV 感染时必须考虑临床和病理评估。
