Detection of Borrelia burgdorferi sensu lato DNA in the blood of wild bison from Bialowieza primeval forest in eastern Poland.

The aim of the present study was to investigate the occurrence of Borrelia burgdorferi sensu lato DNA in a group of 120 wild bison (Bison bonasus) from the Bialowieza Primeval Forest in eastern Poland. The PCR technique revealed the presence of 16S RNA of Borrelia burgdorferi sensu lato in the blood of 16 out of 120 examined animals. DNA amplification by means of primers SC1 and SC2 gave a product with a size of 300-bp. The sequences of the PCR products obtained showed 100% homology with each other and 100% homology with B. burgdorferi s.1. 16S RNA gene DQ111061. Results of this study suggest that wild bison are important in maintaining agents of Lyme borreliosis, and that studies of reservoir competence of this species are indicated.
