Phylogenetic analysis of the spirochete Borrelia microti, a potential agent of relapsing fever in Iran.

ABSTRACT: We report a role for Borrelia microti as a cause of relapsing fever in Iran supported by robust epidemiological evidence. The molecular identity of this spirochete and its relation with other relapsing fever borreliae have, until now, been poorly delineated. We analyzed an isolate of B. microti, obtained from Ornithodoros erraticus ticks, by sequencing four loci (16S rRNA, flaB, glpQ, intragenic spacer [IGS]) and comparing these sequences with those of other relapsing fever borreliae. Phylogenetic analysis using concatenated sequences of 16S rRNA, flaB, and glpQ grouped B. microti alongside three members of the African group, B. duttonii, B. recurrentis, and B. crocidurae, which are distinct from B. persica, the most prevalent established cause of tick-borne relapsing fever in Iran.
