Canine parvovirus 2 (CPV-2) is an important pathogen of domestic dogs and wild canids. In Japan, CPV-2 infection is one of the most common infectious diseases of dogs. We analyzed samples collected between 2014 and 2019 to identify antigenic variants of CPV-2 in dogs in Japan. Our results demonstrated that the CPV-2b variant was predominant. The CPV-2c variant was not found among our samples. Our findings demonstrate that the distribution of CPV-2 antigenic variants in Japan was more similar to that in Australia than to that in neighboring countries in Asia.

日本犬细小病毒 2b 的优势：2014-2019 年的流行病学研究。

犬细小病毒 2 (CPV-2) 是家犬和野生犬科动物的重要病原体。在日本，CPV-2感染是犬最常见的传染病之一。我们分析了 2014 年至 2019 年间收集的样本，以鉴定日本犬类中 CPV-2 的抗原变体。我们的结果表明 CPV-2b 变体占主导地位。在我们的样本中未发现 CPV-2c 变体。我们的研究结果表明，日本 CPV-2 抗原变体的分布与澳大利亚的分布更相似，而不是亚洲邻国的分布。
