Abstract: |
[Objective] The differentation possibility of 16S-23S rRNA spacer reg ion will be evaluated in this study. [Method] Total 183 strains collected from c linical patients were amplified by fluorescence-PCR and then digested by restric tion endonuclease Hae III incompletely. [Result] All the bacteria could be ide nt ified as definitely as the spices level. Different bacteria gave different RFLP patterns. [Conclusion] The method used in this study was a valuable alternativ e to the bacterial differentiation for clinical use. |
