Abstrakt:	Importance: Previous research has implicated Ornithodoros ticks, including Ornithodoros turicata , as long-term reservoirs of relapsing fever (RF) spirochetes. Considering the tick's long lifespan and their efficiency in maintaining and transferring spirochetes within the population, the infection could persist in a given enzootic focus for decades. However, little is known about the relative importance of horizontal and vertical transmission routes in the persistence and evolution of RF Borrelia . Our observations on the reproductive biology of O. turicata in the absence of vertebrate hosts indicate an additional mechanism by which Borrelia turicatae can be maintained in the environment. This work establishes the foundation for studying O. turicata reproduction and spirochete-vector interactions, which will aid in devising control measures for Ornithodoros ticks and RF spirochetes. Competing Interests: The authors declare no conflicts of interest.
