Quantitative detection of Borrelia burgdorferi by real-time PCR.

ABSTRACT: Currently, no easy and reliable methods allowing for the quantification of Borrelia burgdorferi in tissues of infected humans or animals are available. Due to the lack of suitable assays to detect B. burgdorferi CFU and the qualitative nature of the currently performed PCR assays, we decided to exploit the recently developed real-time PCR. This technology measures the release of fluorescent oligonucleotides during the PCR. Flagellin of B. burgdorferi was chosen as the target sequence. A linear quantitative detection range of 5 logs with a calculated detection limit of one to three spirochetes per assay reaction mixture was observed. The fact that no signals were obtained with closely related organisms such as Borrelia hermsii argues for a high specificity of this newly developed method. A
