[Genetic characterization of pathogenic Borrelia, group A14S, isolated in Ukraine].

[Article in Russian]


Borrelia Ir-5215, isolated from ticks Ixodes ricinus in Ukraine (the Crimean autonomous region), was identified by the method of the polymorphism of the fragment length of the restriction amplicon of rRNA spacer region 5S-23S. Its Msel-restriction profile was relatively similar to that of B. afzelii. The sequencing of spacer region rrf (5S)-rrl (23S) and 16S rRNA gene, as well as the analysis of the similarity of nucleotide sequences, obtained in the course of these study, revealed the differences between Borrelia sp, lr-5215 and six European species of Borrelia burgdorferi sensu lato and a high level of similarity (more than 95.1% for 5S-23S rRNA and 99.4% for 16S rRNA gene) to three known representatives of genome group A14S (Borrelia spp. A14S, I-77 and PC-Rq17). This suggests that isolated Borrelia lr-5215 is a new representative of pathogenic B. burgdorferi sensu lato genome group A14S, which is spread, together with Central Europe, also in southern Ukraine.
