摘要：

We designed a polymerase chain reaction (PCR) assay for rapid detection of prokaryotic 16S-23S spacer regions. This PCR assay consisted of nested DNA amplifications. The first-step PCR was able to detect the general presence of eubacteriales with a unified set of universal primers. The universal primers were selected from highly conserved regions in 16S and 23S ribosomal RNA (rRNA) genes and amplified DNAs from all 62 different species of bacteria tested. In the second-step PCR, the identification primers could detect four important bacterial species through amplification of the rRNA spacer regions between the 16S-23S rRNA genes. For Staphylococcus aureus, intraspecies variation in spacer amplification products was observed with S. aureus specific primers. We suggest that the nested PCR assay could be used as a novel method for the identification and typing in epidemiological studies of S. aureus.
