Use of PCR and reverse line blot hybridization assay for rapid simultaneous detection and serovar identification of Chlamydia trachomatis.

ABSTRACT: The aim of this study was to develop and evaluate multiplex and nested PCR-reverse line blot (RLB) hybridization assays for detection and serovar identification of Chlamydia trachomatis. Two sets of primers targeting the VD2 region of the omp1 gene and one set targeting the cryptic plasmid were designed for use in multiplex (both targets) and nested PCR (omp1 only). For the RLB assay, labeled omp1 amplicons were hybridized to a membrane containing probes specific for 15 C. trachomatis serovars. The assays were used to test 429 clinical specimens, which had been previously tested for C. trachomatis using the COBAS AMPLICOR system. Specimens were tested without knowledge of the COBAS AMPLICOR result. Of 205 specimens that were positive by COBAS AMPLICOR, 201 (98%) were positive by multiplex
