Résumé
OBJECTIVE To monitor and analyze the distribution and antibiotic resistance of common bacteria isolated from urine-tract infection patients in our hospital in recent two years and to provide new evidence for clinicians to choose the antibiotics. METHODS We used VITEK system to identify the bacteria,performed the drug-resistant test by K-B and analyzed the distribution and drug resistance of the isolated bacteria by WHONET 5.3 software. RESULTS A tatal of 1379 strains of bacteria were isolated from 2991 urine samples,most of which were Gram-negative bacteria.among which Escherichia coli was the most common.Enterococcus were the most common pathogen of gram-positive bacteria,especially for E.faecalis and E.faecium and fungi infection also increased.The resistance to antibiotics was quite different,manifesting multi-resistance.The detection rates of ESBLs-producing E.Coli,Klebsiella penumoniae and Proteus were 72.1%,69.9% and 34.2%,respectively. CONCLUSIONS It′s of great significance to summarize and analyze the distribution and biotic resistance of isolated bacteria in urine-tract infection to control resistant strains and indicate the choice of antibiotics in clinic.
