Abstract

The prevalence of rickettsiae, ehrlichiae, and the rickettsia-like endosymbiont called Montezuma relative to that of Borrelia was determined in questing Ixodes persulcatus (I. persulcatus) ticks collected in 2002-2003 from Vologda Province, Russia. Ehrlichia muris, Anaplasma phagocytophilum, Montezuma, and new spotted fever group rickettsiae were detected by polymerase chain reaction (PCR) for the first time in this area. The rickettsiae were all Candidatus Rickettsia tarasevichiae, the furthest west this organism has been detected. After Borrelia, Montezuma was the agent most frequently detected; it may be present throughout the distribution of I. persulcatus in Russia. Ehrlichiae and rickettsiae frequently share the same tick host with Borrelia burgdorferi sensu lato so cotransmission and mixed infections in vertebrate hosts, including humans, may occur.

摘要

2002年至2003年期间，在俄罗斯沃洛格达州采集的全沟硬蜱（Ixodes persulcatus）中，测定了立克次氏体、埃立克体以及一种名为蒙特祖马的类立克次氏体共生菌相对于疏螺旋体的流行情况。在该地区首次通过聚合酶链反应（PCR）检测到了鼠埃立克体、嗜吞噬细胞无形体、蒙特祖马以及新的斑点热群立克次氏体。这些立克次氏体均为塔拉舍维奇假立克次氏体（Candidatus Rickettsia tarasevichiae），这是该生物体在最西端被检测到的情况。在疏螺旋体之后，蒙特祖马是最常被检测到的病原体；它可能在俄罗斯全沟硬蜱的整个分布区域都存在。埃立克体和立克次氏体经常与狭义伯氏疏螺旋体（Borrelia burgdorferi sensu lato）共享相同的蜱宿主，因此在包括人类在内的脊椎动物宿主中可能会发生共同传播和混合感染。
