Development of a 5′ Fluorogenic Nuclease-Based Real-Time PCR Assay for Quantitative Detection of Actinobacillus actinomycetemcomitans and Porphyromonas gingivalis

Abstract
A 5′ nuclease TaqMan PCR was developed for the quantitative detection of the periodontopathic bacteria Actinobacillus actinomycetemcomitans and Porphyromonas gingivalis . The relative numbers of bacteria were measured by the comparative threshold cycle method. This simplified method is a way of obtaining the relative quantities of these organisms from specimens and of monitoring the effect of therapy.
