The purpose of this study is to develop the quantitative PCR(qPCR) assay that would enable the rapid identification and simultaneous detection of six different endodontic pathogenic bacteria in a single reaction. In this study, six pairs of primers for Treponema denticola, Porphyromonas gingivalis, Fusobacterium nucleatum, Prevotella intermedia, Streptococcus mutans, and Staphylococcus aureus and two pairs of housekeeping genes were designed for a multiplex qPCR based on the SYBR Green method. The genomic DNA was extracted from reference strains and submitted to the qPCR reaction. The specificity of the amplified products was analyzed by melting curves. As a result, six distinct melting peaks were identified by the melting curve analysis and all of the target species were simultaneously discriminated. Therefore, the multiplex qPCR assay developed in this study can be used for rapid identification and detection of T. denticola, P. gingivalis, F. nucleatum, P. intermedia, S. mutans, and S. aureus at the same time. In combination with the melting curve analysis, the level of the target species and total bacterial load can be obtained.
