Borrelia miyamotoi is an emerging tick-borne pathogen. The vector is ticks of the Ixodes ricinus complex, causing relapsing fever- like disease and widespread in the temperate zone of the Northern Hemisphere. The present study documents the prevalence of B. miyamotoi in Ixodes ricinus ticks at four sites of the South Moravian Region. The spirochete B. miyamotoi was detected in a total of 10 samples from all four sites and all instars. The occurrence of B. miyamotoi in ticks in the Czech Republic poses a potential risk to public health.
