This study aims to investigate the presence of canine distemper virus (CDV) infection in 949 autochthonous or illegally imported dogs from Southern Italy, over a period of eight years (2014-2021). CDV RNA was detected in 6.8% (65/949) of the animals tested, with no detection of CDV in dogs sampled in 2020-2021. The frequency of CDV detection was higher in imported dogs (19/103, 18.3%) with respect to stray (27/365, 7.4%) and household dogs (19/481, 3.9%). On sequence and phylogenetic analyses of selected strains, the analyzed viruses belonged to the Arctic clade, which has already been reported in Italy and in Europe. The results of our study may suggest a reduction of CDV circulation in Southern Italy, while at the same time highlighting the need for strict controls on dog importation, in order to prevent the introduction of viruses from endemic countries.
本研究旨在调查8年间（2014 - 2021年）从意大利南部本地或非法进口的949只犬中犬瘟热病毒（CDV）感染情况。在检测的动物中，6.8%（65/949）检测到CDV RNA，2020 - 2021年采集的犬只未检测到CDV。进口犬中CDV检测频率（19/103，18.3%）高于流浪犬（27/365，7.4%）和家养犬（19/481，3.9%）。对选定毒株进行序列和系统发育分析，分析的病毒属于北极分支，该分支已在意大利和欧洲有报道。我们的研究结果可能表明意大利南部CDV传播有所减少，同时强调需要严格控制犬只进口，以防止来自流行国家的病毒传入。
