Distribution and drug resistance of Klebsiella pneumoniae from 2011 to 2013 in a hospital / 国际检验医学杂志

ABSTRACT

Objective The distribution and drug resistance of Klebsiella pneumonia isolated from clinical department were ana‐lyzed in this article .It will provide evidence for the clinical rational medication and the control of nosocomial infections .Methods In this hospital ,892 strains of Klebsiella pneumonia isolated from January 2011 to December 2013 were performed a statistical analy‐sis .Results Among all the samples ,the extended spectrumβ‐lactamases(ESBLs) positive Klebsiella pneumoniae accounted for 40 . 92% .The highest detection rate in the all the clinical department is the ICU with a value of 46 .46% .The highest detection rate in the sample is the sputum with a value of 43 .51% .In addition ,the ESBLs positive strains had a trend of multiple drug resistance . The Klebsiella pneumonia was the most sensitive bacteria to imipenem ,meropenem ,piperacillin/tazobactam and cefoperazone/sul‐bactam ,no matter whether they produced ESBLs or not .Conclusion The resistant rate of ESBLs positive strains is higher than that of ESBLs negative strains .It was recommended to the rational use of antibiotics based on the duration of disease and the products with or without ESBLs .Furthermore ,it will be of great importance to reduce the incidence of multiple drug resistance ,and to con‐trol the hospital infection effectively .
