The two of three species of city-inhabiting (Warsaw, Poland) spp. mice were showed to be infected with spirochete bacterium considered to be a tick-borne relapsing fever (TBRF) disease causative agent. The pathogen infection was ascertained based on bacterium DNA presence in a blood (obtained from the lateral tail vein) of the mice, using the nested polymerase chain reaction (PCR) technique. The carriers populated not only green spaces situated in the suburban areas but also recreational parks and lawns in the city centre proper. Moreover, we found no significant differences in the infection rate depending on mouse species. The total prevalence of infection at the level of 5.6% suggests the potential role of urban-settled rodents in the spreading of the tick-borne zoonosis, which pose high risk to public health.
在波兰华沙市内栖息的三种小鼠中，有两种被发现感染了一种螺旋体细菌，该细菌被认为是蜱传回归热（TBRF）疾病的病原体。基于从小鼠（从尾静脉外侧采集）血液中检测到细菌DNA，利用巢式聚合酶链反应（PCR）技术确定了病原体感染情况。这些携带者不仅分布在郊区的绿地，也分布在市中心的休闲公园和草坪。此外，我们发现感染率在不同小鼠物种之间没有显著差异。5.6%的总体感染率表明城市定居啮齿动物在蜱传人畜共患病传播中可能发挥的作用，这对公众健康构成了高风险。
