荆门蜱病毒（Jingmen tick virus，JMTV）及其相关的荆门病毒--阿龙山病毒（Alongshan virus）是全球新发现的人类致病性蜱传病毒。这些病毒已在各种哺乳动物和无脊椎动物中被检测到，尽管它们的自然传播周期仍然未知。在日本对蜱传病毒的监测中，现已鉴定出JMTV和一种新的荆门病毒，暂命名为Takachi病毒（TAKV）。JMTV已被证明分布在日本的广泛地区，并已在相同的收集地点在几年内多次检测到，这表明在这些地区的自然传播周期中的病毒循环。有趣的是，这些荆门病毒可能以宿主蜱种特异性方式存在。在自然界宿主蜱中的垂直传播的病毒也表明了存在的JMTV在未喂养的主机探索Amblyomma testudinarium幼虫。进一步的流行病学监测和病原学研究是必要的，以评估在日本的荆门病毒感染的现状和风险。
Jingmen tick virus (JMTV) and the related jingmenvirus-termed Alongshan virus are recognized as globally emerging human pathogenic tick-borne viruses. These viruses have been detected in various mammals and invertebrates, although their natural transmission cycles remain unknown. JMTV and a novel jingmenvirus, tentatively named Takachi virus (TAKV), have now been identified during a surveillance of tick-borne viruses in Japan. JMTV was shown to be distributed across extensive areas of Japan and has been detected repeatedly at the same collection sites over several years, suggesting viral circulation in natural transmission cycles in these areas. Interestingly, these jingmenviruses may exist in a host tick species-specific manner. Vertical transmission of the virus in host ticks in nature was also indicated by the presence of JMTV in unfed host-questing Amblyomma testudinarium larvae. Further epidemiological surveillance and etiological studies are necessary to assess the status and risk of jingmenvirus infection in Japan.
