Identification of Borrelia burgdorferi sensu lato tick isolates from Slovakia by PCR typing with 16S rRNA primers.

The first four strains of Borrelia burgdorferi isolated in Slovakia from ticks and mice were studied using monoclonal antibodies, the polymerase chain reaction (PCR) with 16S rRNA specific primers and plasmid profiles. Two tick isolates were typed as Borrelia garinii, one strain isolated from Apodemus flavicollis was found to be B. afzelii and the fourth tick isolate reacted as a mixed culture of B. garinii and B. afzelii. All four strains harboured several plasmids ranging from 6-50 kbp including a plasmid with a size of approximately 41 kbp.
