Abstract

Prevalence of relapsing fever spirochete Borrelia miyamotoi in Ixodes ricinus ticks from eastern Slovakia.

Abstract

Borrelia miyamotoi, recurrent fever borrelia, pathogenic to humans, has been found recently in Ixodes ricinus ticks. There is still little information about its circulation in nature and potential local impact on human health as well as the occurrence in natural localities. In our study, a total of 1609 ticks (745 nymphs, 358 females and 506 males) collected from different localities in eastern Slovakia were analysed using a polymerase chain reaction targeting a gene encoding glycerophosphodiester phosphodiesterase (glpQ), which is specific to the Borrelia species in the relapsing fever group. B. miyamotoi was found in 3 nymphs, 6 females and 9 males of quested I. ricinus ticks. Although no human case of infection with B. miyamotoi has been reported in Slovakia yet, its presence needs to be studied to obtain knowledge regarding the prevalence and the distribution of this human pathogen in questing ticks and to increase medical healthcare awareness.
