摘要

猫肠道冠状病毒（FECoV）会引起亚临床感染；因此，无症状的猫可能成为 FECoV 的传播者。然而，关于 FECoV 在日本无症状猫中的流行率的研究却很少。在本研究中，我们使用针对 FECoV S 基因的巢式 RT-PCR 检测法，检测了 2019 年至 2020 年期间日本流浪猫和家猫的 319 份正常粪便样本。有 75 份样本检测结果呈阳性，家猫体内 FECoV 的存在与年龄显著相关（p

Molecular epidemiology and risk analysis for asymptomatic infection with feline enteric coronavirus in domestic and stray cats in Japan

Feline enteric coronavirus (FECoV) causes subclinical infection; therefore, asymptomatic cats can act as transmitters of FECoV. However, there have been few studies on the prevalence of FECoV in asymptomatic cats in Japan. In this study, we used a nested RT-PCR assay targeting the S gene of FECoV to test 319 normal fecal samples from stray cats and domestic cats in Japan between 2019 and 2020. Seventy-five samples tested positive, and the presence of FECoV in domestic cats was significantly associated with age (p < 0.01), but not with gender, breed, or living in a multi-cat household. The results provide insights into the current prevalence of FECoV in asymptomatic cats in Japan.

期刊介绍： Archives of Virology publishes original contributions from all branches of research on viruses, virus-like agents, and virus infections of humans, animals, plants, insects, and bacteria. Coverage spans a broad spectrum of topics, from descriptions of newly discovered viruses, to studies of virus structure, composition, and genetics, to studies of virus interactions with host cells, organisms and populations. Studies employ molecular biologic, molecular genetics, and current immunologic and epidemiologic approaches. Contents include studies on the molecular pathogenesis, pathophysiology, and genetics of virus infections in individual hosts, and studies on the molecular epidemiology of virus infections in populations. Also included are studies involving applied research such as diagnostic technology development, monoclonal antibody panel development, vaccine development, and antiviral drug development.Archives of Virology wishes to publish obituaries of recently deceased well-known virologists and leading figures in virology.
