During spring-autumn period of 2006 Borrelia were isolated for the first time in Russia from blood of 79 patients treated in Perm City Clinical Hospital for Infectious Diseases No. 1 with diagnosis "tickborne borreliosis, manifestive form with migrating erythema, localized stage". Ten primary isolates (12.7% of total seeded samples) were obtained by seeding plasma samples on the BSK medium. Their subsequent identification by polymerase chain reaction-restriction fragments length polymorphism revealed presence of Borrelia garinii NT29 in all patients. Length of sequenced fragment of rrfA-rrlB region was 253 b.p. Seven isolates had 100% and 3 - 99.6% similarity with typical strain NT29 (L30130). Nucleotide sequences of 4 obtained isolates were deposited in GenBank database (No. AM932199 - AM932202). It was proposed that B. garinii NT29 more frequently than other Borrelia species can be an etiologic agent of tick-borne borreliosis not only in Perm region but also in whole Russia.
