Serum samples from 19 jaguars (Panthera onca), nine pumas (Puma concolor), and two ocelots (Leopardus pardalis) were collected between January 1999 and March of 2005 and tested for presence of canine distemper virus (CDV). All cats were free-ranging animals living in two protected areas in the Brazilian Atlantic Forest. In addition, 111 domestic dogs from nearby areas were sampled for CDV. Our results show the first evidence of CDV exposure in Brazilian free-ranging felids. From the 30 samples analyzed, six jaguars and one puma were tested seropositive for CDV. All seropositive large felids were from Ivinhema State Park, resulting in 31.5% of the sampled jaguars or 60% of the total jaguar population in Ivinhema State Park, and 11.28% of the sampled pumas. From the total 111 domestic dogs sampled, 45 were tested seropositive for CDV. At Morro do Diabo State Park, 34.6% of the dogs sampled were positive for CDV, and 100% at Ivinhema State Park. Canine distemper virus in wild felids seems to be related with home range use and in close association with domestic dogs living in nearby areas.
1999年1月至2005年3月期间，采集了19只美洲豹（Panthera onca）、9只美洲狮（Puma concolor）和2只豹猫（Leopardus pardalis）的血清样本，检测是否存在犬瘟热病毒（CDV）。所有猫科动物均为生活在巴西大西洋森林两个保护区的野生自由放养动物。此外，还对附近地区的111只家犬进行了CDV采样。我们的结果首次证明了巴西野生自由放养猫科动物接触过CDV。在分析的30个样本中，6只美洲豹和1只美洲狮的CDV检测呈血清阳性。所有血清阳性的大型猫科动物均来自伊维内马州立公园，占采样美洲豹的31.5%，或伊维内马州立公园美洲豹总数的60%，以及采样美洲狮的11.28%。在总共采样的111只家犬中，45只CDV检测呈血清阳性。在莫罗迪阿波州立公园，34.6%的采样犬CDV检测呈阳性，而在伊维内马州立公园这一比例为100%。野生猫科动物中的犬瘟热病毒似乎与活动范围的使用有关，并且与生活在附近地区的家犬密切相关。
