Porcine astroviruses (PAstVs) are common and genetically diverse viruses of domestic pigs. In the present study, the prevalence of PAstV in healthy domestic pigs in Croatia was 89%. Phylogenetic analysis revealed genetic heterogeneity among PAstV sequences; five lineages were detected, with PAstV-2 being predominant, while PAstV-3 was detected for the first time outside North America.
猪星状病毒（PAstVs）是家猪中常见且基因多样的病毒。在本研究中，克罗地亚健康家猪中PAstV的流行率为89%。系统发育分析揭示了PAstV序列之间的遗传异质性；检测到五个谱系，其中PAstV-2占主导地位，而PAstV-3首次在北美以外地区被检测到。
