Minute virus of canines (MVC) belongs to the family Parvoviridae, genus Bocaparvovirus, and has been mainly described during enteritis episodes in young dogs. This study reports the characterization of four divergent MVC strains detected between 2012 and 2018, three of which were from dogs illegally imported into Italy, most probably from Eastern Europe, that cluster together phylogenetically but share low genetic similarity with the fourth MVC from an autochthonous dog and other available MVC sequences. Our data indicate that the introduction of genetically distinct MVC strains occurred through the illegal movement of dogs from a geographic area where a distinct MVC lineage was most likely circulating. Enforced surveillance of MVC in the dog population of Eastern Europe and its neighboring countries may shed light on, and eventually trace back to, illegal animal movements.

犬细小病毒（MVC）属于细小病毒科，Bocaparvovirus属，主要描述在幼犬的肠炎发作期间。这项研究报告了在2012年至2018年之间检测到的四种不同MVC株的特征，其中三株来自非法进口到意大利的狗，最有可能是从东欧的狗，它们在系统发育上聚集在一起，但与第四条来自本地狗的MVC的遗传相似性低和其他可用的MVC序列。我们的数据表明，遗传上独特的MVC株系的引入是通过狗从最有可能出现独特MVC血统的地理区域的非法移动而发生的。在东欧及其邻国的狗群中对MVC进行强制监视可能会发现并最终追溯到非法动物运动。
