Carios kelleyi (Colley & Kohls 1941), a tick associated with bats and bat habitats, has been reported to feed on humans, but there is little published data regarding the presence of vector-borne pathogens in these ticks. C. kelleyi nymphs and adults were collected from residential and community buildings in Jackson County, Iowa, and tested by polymerase chain reaction for Rickettsia, Borrelia, Bartonella, Coxiella, and Anaplasma. Rickettsia DNA was detected in 28 of 31 live ticks. Sequences of the 17-kDa and rOmpA genes suggest that this agent is a novel spotted fever group Rickettsia. Transstadial and transovarial transmission of this Rickettsia were demonstrated. The flagellin gene of a Borrelia, closely related to B. turicatae, was detected in one of 31 live ticks. The 16S-23S intergenic spacer region of Bartonella henselae also was detected in one of 31 live ticks. Coxiella or A. phagocytophilum DNA were not detected in these ticks.
凯利硬蜱（Carios kelleyi，由科利和科尔于1941年发现）是一种与蝙蝠及其栖息地相关的蜱虫，已有报道称其会叮咬人类，但关于这些蜱虫中媒介传播病原体存在情况的公开数据很少。从爱荷华州杰克逊县的住宅和社区建筑中采集了凯利硬蜱的若虫和成虫，并通过聚合酶链反应检测其中的立克次体、疏螺旋体、巴尔通体、柯克斯体和无形体。在31只存活的蜱虫中，有28只检测到立克次体DNA。17-kDa和rOmpA基因的序列表明，该病原体是一种新型斑点热群立克次体。已证实这种立克次体可经变态期和经卵传播。在31只存活的蜱虫中，有1只检测到一种与图赖疏螺旋体密切相关的疏螺旋体的鞭毛蛋白基因。在31只存活的蜱虫中，还有1只检测到亨氏巴尔通体的16S - 23S基因间隔区。在这些蜱虫中未检测到柯克斯体或嗜吞噬细胞无形体的DNA。
