目的:气单胞菌属。经常导致危及生命的疾病,包括坏死性筋膜炎,这可能会导致感染性休克,最终导致死亡。气单胞菌感染被认为是通过轻微伤口或食用新鲜鱼类传播的。然而,在日本斑点热(JSF)流行地区的蜱中检测到嗜水气单胞菌后,嗜水气单胞菌的一种新的传播途径(即通过蜱叮咬)已被提出。WeinvestigatedthepreventedofA.hydrophilaintickinareasentricicandnotentricictoJSFintheMieCountry,日本。
方法:我们在夏季和冬季收集了地方性和非地方性地区的蜱,并使用聚合酶链反应评估了它们是否存在嗜水气单胞菌。
结果:从流行地区的95个蜱中获得了6个嗜水气单胞菌分离株,而从非流行地区的142只蜱中获得了一种嗜水气单胞菌分离物,在夏天。所有藏有嗜水菌的蜱都是长鱼眼(H.L);这些蜱几乎处于幼虫阶段,也带有立克次体。在流行区。相比之下,冬季在流行区和非流行区捕获了51只和41只蜱,分别;在这些中没有检测到亲水A。
结论:这项研究揭示了蜱媒嗜水气单胞菌的患病率。因此,在以下情况下,应考虑通过蜱叮咬传播嗜水气单胞菌的风险:H.L.,在JSF特有的地区,在幼虫阶段和夏季期间存在蜱。
Aeromonas spp. often cause life-threatening diseases, including necrotizing fasciitis, which may lead to septic shock and ultimately death. Aeromonas infections are believed to be transmitted via minor wounds or the consumption of fresh fish. However, after the detection of Aeromonas hydrophila in ticks in areas endemic to Japanese-spotted fever (JSF), a novel transmission route of A. hydrophila (i.e., via tick bites) has been proposed. We investigated the prevalence of A. hydrophila in ticks in areas endemic and not endemic to JSF in the Mie Prefecture, Japan.
We collected ticks from endemic and nonendemic areas in summer and winter and assessed them for presence of A. hydrophila using polymerase chain reaction.
Six A. hydrophila isolates were obtained from 95 ticks in endemic areas, whereas one A. hydrophila isolate was obtained from 142 ticks in non-endemic areas, in summer. All ticks that harboured A. hydrophila were Haemaphysalis longicornis (H.L); these ticks were almost at the larval stage and also carried Rickettsia spp. in the endemic area. In contrast, 51 and 41 ticks in the endemic and non-endemic areas were captured in winter, respectively; A. hydrophila was not detected in these.
This
study revealed the prevalence of tick-borne A. hydrophila. Therefore, the risk of transmission of A. hydrophila via a tick bite should be considered in the following conditions: areas abundant in H. L. harbouring Rickettsia spp., in areas endemic for JSF, presence of ticks in the larval stage and during the summer season.
