[Isolation of Borrelia burgdorferi sensu lato in ticks Ixodes ricinus by polymerase chain reaction (PCR)].

Attempts were made to identify the causative orgamsm of Lyme disease in Szczecin from tick Ixodes ricinus as a vector. Ticks were collected in 1997 year in forest areas of Szczecin, from localites associated with numerous attendance of people. The method used in this study was the polymerase chain reaction (PCR) on the flagellin structural gene fla of Borrelia burgdorferi sensu stricto. The flagellin PCR primer set reaction was conservative for B. burgdorferi sensu stricto, B. afzelii and B. garinii. The overall prevalence of B. burgdorferi sensu lato, in tick population studied was 8.8%. The female, nymphs and larves of Ixodes ricinus were infected almost just the some--about 10%, when the male 2.5% only.
