Abstract:
Objective To investigate the clinical distribution and resistance change of pseudomonas aeruginosa (PAE) in the four hospitals of Henan province during 2012-2015,so as to provide guidance for reasonable clinical use of antibiotics.Methods By means of disk diffusion method (K-B method) or automatic instrument,the drug susceptibility testing was performed for the clinical isolated strain which collected from the 371st Central Hospital of PLA,the Third Affiliated Hospital of Xinxiang Medical University,the 150th Central Hospital of PLA and the 153rd Central Hospital of PLA during 2012-2015,then the result were interpreted according to the criteria of Clinical and Laboratory Standards Institute 2010,and the date were analyzed by using WHONET 5.6 software.Results A total of 1 796 strains of PAE had been isolated,and mainly distributed in department of critical care medicine (32.6％) and department of gastroenterology (28.7％).The specimens mainly collected from sputum (74.6％) and wound secretion (9.6％).The drug susceptibility results showed that the antibiotic sensitive rate of PAE to polymyxin B(93.5％) was the highest,followed by the piperacillin/tazobactam(78.2％) and amikacin(76.2％).Resistance rate of PAE to piperacillin(34.4％) was the highest,followed by the ticarcillin/calvulanic acid(34.1％) and aztreonam (30.7 ％).Drug-resistance of PAE to the ceftazidime,cefepime,aztreonam,amikacin,gentamicin and polymyxin B had a downward trend,respectively.Conclusion Drug-resistance of the PAE to the most commonly used antimicrobial has a downward trend.However,the drug-resistance situation of PAE is very serious and the resistance rates still keep the high level during 2012-2015.It is necessary to investigate the clinical distribution and resistance of PAE,so as to provide guidance for reasonable clinical use of antibiotics.
