蜱传播病原体并寄生于野生动物，从而在许多生态系统中引起人畜共患疾病。蛾蜱，如鸟蜱，携带和传播伯氏疏螺旋体，导致人们患上蜱传回归热。在美国西部，TBRF通常与高海拔（约1500英尺）栖息地中发现的受感染的hermsi鸟蜱叮咬有关。本报告描述了莫哈韦沙漠（内华达州克拉克县）人群中首例TBRF病例。在这些案例研究中记录的个体在挖掘与莫哈韦沙漠象龟（Gopherus agassizii）相关的土壤洞穴时暴露于鸟thodoros蜱虫，通过定量PCR和测序确定，其中一名人类病例血液样本中的细菌与turicatae Borrelia基因匹配。我们的研究结果应该为在该地区与乌龟或动物洞穴工作的个人或与鸟thodoros蜱接触的人提供预防措施。
Ticks transmit pathogens and parasitize wildlife in turn causing zoonotic diseases in many ecosystems. Argasid ticks, such as Ornithodoros spp., harbor and transmit Borrelia spp., resulting in tick-borne relapsing fever (TBRF) in people. In the western United States, TBRF is typically associated with the bite of an infected Ornithodoros hermsi tick found in habitats at high elevations (>1500 ft). This report describes the first TBRF cases in people in the Mojave Desert (Clark County, NV). Individuals documented in these case studies were exposed to Ornithodoros ticks during excavation of soil burrows associated with Mojave Desert tortoises (Gopherus agassizii), with bacteria from one of the human case's blood sample genetically matching to Borrelia turicatae as determined by quantitative PCR and sequencing. Our findings should serve as a precaution to individuals working with tortoises or animal burrows, or those in contact with Ornithodoros ticks in this region.
