Isolation and Molecular Characterization of Tick-Borne Relapsing Fever Borrelia Infecting Ornithodoros (Pavlovskyella) verrucosus Ticks Collected in Ukraine

摘要

Background. Tick-borne relapsing fever (TBRF) is a neglected zoonotic bacterial disease known to occur on 5 continents. We report a laboratory-acquired case of TBRF caused by Borrelia caucasica, which is endemic in Ukraine and transmitted by Ornithodoros verrucosus ticks.
