摘要

To the Editor: Tick-borne relaps-ing fever in western North America is a zoonosis caused by spirochetes in the genus Borrelia that are transmit-ted by argasid ticks of the genus Or-nithodoros (1). Human disease occurs in many focal areas and is associated with infections of Borrelia hermsii, B. turicatae, and possibly B. parkeri (2,3). Although the ecologic param-eters that maintain B. hermsii and B. turicatae differ, human infections usu-ally occur in rustic cabins (B. hermsii) and caves (B. turicatae) inhabited by ticks and their terrestrial vertebrate hosts (1). Recently, Gill et al. (4) pro-vided evidence that the argasid bat tick, Carios kelleyi, feeds upon hu-mans. Subsequently, Loftis et al. (5) used PCR analysis and DNA sequenc-ing to detect in C. kelleyi an unidenti-fi ed Borrelia species that was closely related to B. turicatae and B. parkeri. We report the partial molecular char-acterization of another novel tick-borne relapsing fever spirochete in C. kelleyi, which expands our knowledge for this group of pathogenic spiro-chetes and their potential vertebrate hosts and tick vectors.C. kelleyi were collected Au-gust 18, 2005, from a house in Jones County, Iowa, built in 1857. Bats had been excluded from the attic since 1992. Nine months before ticks were collected, bats were prevented from roosting under the eaves. DNA was extracted from 31 nymphal C. kel-leyi, as described previously (6). For each tick, regions of the glpQ, . aB, and 16S rRNA genes were amplifi ed and sequenced as described (3,7,8). Sequences were assembled by using the SeqMan program in the Lasergene software package (DNASTAR, Madi-son, WI, USA).
