Abstract:
OBJECTIVE To investigate the distribution of clinical commonly encountered pathogens and their drug resistance in our hospital,and provide reference for reasonable choices of the clinical antibiotics.METHODS The K-B method was used to test the sensitivity to antibiotics of 859 strains pathogens isolated from all kinds of infected samples during from Jan to Dec 2006 in our hospital,at the same time the ESBLs of Escherichia coli and Klebsiella and the MRS were detected.RESULTS The more pathogens isolated from our hospital were E.coli,Staphylococcus,Pseudomonas aeruginosa,Klebsiella,Acinetobacter and Enterococcus.The ESBLs isolating rate was 32.8% in E.coli and 29.4% in Klebsiella,and the sensitivity to antibiotics was degraded obviously in those ESBLs producing strains.Imipenem was the most effective antibiotic to Gram-negative bacilli,cefoperazone/sulbactam and piperacillin/tazobactam also had better antibacterial activity.The isolating rate of MRSA and MRCNS was 32.6% and 40.7% in S.aureus and MRCNS.Gram-positive cocci had the best sensitivity to vancomycin.There was no drug-resistant Enterococcus strain to vancomycin being found.CONCLUSIONS We should think highly of the bacterial drug resistance and use antibiotics reasonably.
