Abstract:
Objective To understand the isolation and change of drug resistance of mucoid Pseudomonas aeruginosa in sputum from 2013 to 2015 so as to provide a scientific basis for reasonable clinical use of antibacterial drugs.Methods The isolation,culture and identification were carried out according to the fourth edition of National Clinical Laboratory Operation Rules.The drug susceptibility testing was performed with the use of Kindy-Bauer.The drug susceptibility testing results were judged according to the standards of CLSI 2014.The clinical data were analyzed by software WHONET 5.6.Results Among 1 653 strains of Pseudomonas aeruginosa isolated in the clinical sputum specimens from 2013 to 2015,including 255(15.4%)strains of mucoid Pseudomonas aeruginosa;during the three years,the drugs of highest drug resistance rate was piperacillin,which was 29.0%;the drug resistance rate less than 10.0% had amikacin and piperacillin/tazobactam;the drugs with larger increase range of resistance rate included imipenem,levofloxacin,ciprofloxacin and ciprofloxacin,their resistance rates were increased from 12.5%,9.7%,8.3% and 9.7% in 2013 to 20.5%,17.0%,19.3% and 15.9% in 2015.Conclusion The isolating rate of mucoid Pseudomonas aeruginosa in sputm is gradually increased year by year from 2013 to 2015.At the same time,the drug resistance rates show an increasing trend in recent three years.It is necessary to strengthen the surveillance of drug resistance of mucoid Pseudomonas aeruginosa.
