Establishment of an analytical system for the human fecal microbiota, based on reverse transcription-quantitative PCR targeting of multicopy rRNA molecules.

ABSTRACT: An analytical system based on rRNA-targeted reverse transcription-quantitative PCR (RT-qPCR) was established for the precise evaluation of human intestinal microbiota. Group- and species-specific primer sets for Clostridium perfringens, Lactobacillus spp. (six subgroups and three species), Enterococcus spp., and Staphylococcus spp. targeting 16S rRNA gene sequences were newly developed for the quantitative analysis of such subdominant populations in human intestines. They were used together with previously reported group-specific primer sets for Enterobacteriaceae, Pseudomonas spp., and six predominant bacterial groups (the Clostridium coccoides group, the Clostridium leptum subgroup, the Bacteroides fragilis group, Bifidobacterium spp., the Atopobium cluster, and Prevotella spp.) for the
