Small-ruminant lentivirus (SRLV) infections are widespread in Poland, and circulation of subtypes A1, A12, A13, A16, A17, B1 and B2 has been documented. The aim of this study was to characterize the SRLV strains circulating in sheep and goats in mixed flocks in the Malopolska region, where the highest seroprevalence has been detected. Phylogenetic analysis revealed that most of the isolates from sheep belonged to subtype A13, suggesting that this subtype may be predominant in the Malopolska region. Furthermore, the existence of a new subtype, tentatively designated as A18, was described for the first time. This work extends the current knowledge on the distribution of SRLV subtypes in sheep and goats in Poland and provides further information on the genetic diversity of SRLV. The new data are important for both epidemiological studies and eradication programs and provide insight into the evolution of SRLV.
小反刍兽疫病毒（SRLV）感染在波兰广泛存在，并且已记录到A1、A12、A13、A16、A17、B1和B2亚型的传播情况。本研究的目的是对在马佐夫舍地区混合羊群中绵羊和山羊体内传播的SRLV毒株进行特征分析，该地区检测到的血清阳性率最高。系统发育分析表明，大多数来自绵羊的分离株属于A13亚型，这表明该亚型可能在马佐夫舍地区占主导地位。此外，首次描述了一种新的亚型，暂定名为A18。这项工作扩展了目前关于波兰绵羊和山羊中SRLV亚型分布的知识，并提供了有关SRLV遗传多样性的进一步信息。这些新数据对流行病学研究和根除计划都很重要，并为SRLV的进化提供了见解。
