Borrelia miyamotoiis an emerging pathogen that shares high similarity with relapsing fever Borrelia,but has an atypical clinical presentation. Within the framework of tick-borne disease surveillance in Finland, human serum samples suspected for tick-borne encephalitis (n=974) and questing ticks (n=739) were collected from the capital region in Finland to determine the prevalence of B. miyamotoi.All tested human samples were negative and 5 (0.68 %) Ixodes ricinusticks were positive for B. miyamotoi. Partial sequencing of the flagellin (flaB) gene of 3 positive samples and 27 B. miyamotoi-positive tick samples obtained from previous studies across Finland were amplified, sequenced, and included in the phylogenetic analysis.
