RESUMEN

The purpose of this research was to understand fecal micro-flora of Enterococcus-related diarrhea feces and the clone characteristics of isolated Enterococcus strains.Primer was designed according to 16S rRNA gene and integrated DNA extracted from patients' fecal samples was used as the template to amplify the conserved sequence of 16S rRNA by PCR.After the PCR product was purified and cloned into T vector to sequence,PFGE was used to analyze 20 out of 50 Enterococcus isolates from each specimen.The 16S rRNA gene sequencing analysis indicated that these 4 portions of diarrhea feces were dominated by Enterococcus faecium (>68%) and the isolates were clonal except only one portion.Although the basic flora characteristics of diarrhea feces could be revealed by 16S rRNA gene sequencing analysis and PFGE analysis,the pathogenicity and mechanism of Enterococcus were still waiting for further experimental exploration.
