Jingmen tick virus (JMTV) is a tick-borne segmented positive-sense ssRNA virus that can cause human disease. This virus has been confirmed to be widespread, having a wide host range. In human it can cause fever, headache, lymphadenopathy, and asthenia. Therefore, JMTV poses a threat to public health. In this study, we collected 478 ticks from imported cattle on three quarantine farms near the Yunnan border to detect medically significant tick-borne viruses. Our findings show that JMTV was the only detected virus, with an incidence rate of 56.67%. Phylogenetic analysis showed that our JMTV is more closely related to previously reported JMTV strains from Yunnan Province and neighboring Laos, implying that the tick-borne virus was most likely imported from Laos. In conclusion, we identified and characterized a novel JMTV strain in tick ) from Yunnan imported cattle, emphasizing the importance of arbovirus quarantine of livestock imports.
荆门病毒（JMTV）是一种蜱传分节正链 ssRNA 病毒，可引起人类疾病。该病毒分布广泛，宿主范围广泛。在人类中，它可引起发热、头痛、淋巴结病和乏力。因此，JMTV 对公共卫生构成威胁。在这项研究中，我们从云南边境附近的三个隔离农场采集了 478 只进口牛蜱，以检测具有医学意义的蜱传病毒。我们的研究结果表明，JMTV 是唯一检测到的病毒，其发病率为 56.67%。系统进化分析表明，我们的 JMTV 与之前报道的来自云南省和邻国老挝的 JMTV 株更为密切相关，这表明这种蜱传病毒很可能是从老挝进口的。总之，我们从云南进口牛蜱中鉴定并描述了一种新型 JMTV 株，强调了对牲畜进口的虫媒病毒检疫的重要性。
