Polymerase chain reaction (pcr) for detection of borrelia burgdorferi sensu lato

Duman, Zeynep
The present study aimed detection of a human pathogen B. bugdorferi sensu lato species in suspected Lyme borreliosis (LB) patients in Turkey by PCR analysis and supportive serologic tests. The 152 clinical samples (140 serum and blood, 10 cerebrospinal fluid (CSF), 1 synovial fluid, 1 skin biopsy specimens) from 140 patients sent from 22 different cities of Turkey to The Spirochetal Diseases Diagnosis Laboratory of Central Veterinary Control and Research Institute were analysed. Serum samples were subjected to ELISA with a commercial kit and all of the blood, CSF, synovial fluid and skin biopsy samples were examined by PCR. In PCR analysis two primer sets targeting the ospA gene located on the plasmid and ribosomal 23S rRNA gene of B. burgdorferi sensu lato were used. The results indicated that 32,1% (45 of 140) seropositivity was detectable by ELISA. Our results support that there is a risk of acquiring LB in different regions of Turkey. Although considerable positive detections were recorded using serologic tests,none of the specimens were positive in PCR analysis. Further studies on PCR based methods for detection of B. burgdorferi sensu lato in patients with a high clinical probability of LB apparently may require that the specimen should be taken in the early phases and before the administration of any therapeutic agent.
