Abstract:
Objective To investigate the drug resistance tendency of Klebsiella pneumoniae isolated from the clinical samples during 2012-2014 to provide reliable evidence for clinical treatment .Methods The Klebsiella pneumoniae strains isolated from the submitted specimens were collected and identified according to the national clinical test procedures ,and the drug sensitivity test was performed by using MIC method .The confirmation test of ESBLs was conducted by using K‐B method and the phenotype of carbap‐enemases producing was confirmed by using the improved Hodge test .Results Totally 410 strains of Klebsiella pneumoniae were i‐solated ,55 .87% of which were derived from sputum ,and the rest was derived from pus(9 .53% ) ,secretion(9 .47% ) and blood (8 .78% );Klebsiella pneumoniae was mainly originated from ICU ,respiration department and oncology department ,accounting for 16 .10% ,9 .02% and 7 .80% respectively ;the resistance rates of Klebsiella pneumoniae against imipenem was 0 .74% ,the resist‐ance rates of Klebsiella pneumoniae against ampicillin/sulbactam ,cafazolin ,cefepime ,cefotaxime ,cefatriaxone ,ceftazidine ,compound sulfamethoxazole were decreased year by year ,while which against amoxicillin/clavulanic acid showed the increasing trend as a whole .Conclusion Timely conducting the identification and drug susceptibility analysis on local Klebsiella pneumoniae and tracking its drug resistance trend can guide the rational and standardized use of antibacterial drugs ,reduces the pressure for selecting anti‐bacterial drugs in order to reduce the generation of drug resistant strains .
