Abstract： Objective To identify the bacteria fragiles(B.fragiles)by 16S target rRNA realtime PCR.Methods A pair of specific primers was designed.The PCR products were detected by fluorescent quantificative realtime PCR.Results The B.fragilis ATCC 25285 and 4 separative strains of B.fragilis appeared in the special amplification product curve,while E.coli,L.bulgaricus and S.thermophilus did not.The flourescent qantificative PCR can detect 102 bacteria.Conclusion 16S rRNAtargeted primer and fluorescent quantifive realtime PCR can be applicable for the identification and quantification of B.fragilis.
