The change analysis of drug resistance of Pseudomonas aeruginosa / 国际检验医学杂志

ABSTRACT

Objective To retrospective analyze the specimens and wards distribution and the drug resistance changes of clinical i‐solated Pseudomonas aeruginosa .Methods 1 114 strains of Pseudomonas aeruginosa were isolated from a variety of clinical speci‐mens for the identification and susceptibility testing by using Microscan Walkaway40 identification and antibiotic susceptibility anal‐ysis system and manual method from 2002 to 2012 .And the results were analyzed .Results In all of the 1 114 isolated Pseudomonas aeruginosa strains ,there were 64 .18% of them from respiratory specimens .Pseudomonas aeruginosa infection occured mainly in the ICU wards (49 .64% ) .From 2002 to 2012 ,the drug resistance rates of Pseudomonas aeruginosa to 19 kinds of antibacterial drugs increased year by year .Conclusion Pseudomonas aeruginosa often causes respiratory tract infection ,and its mechanism of drug resistance is complex .There are few alternative antimicrobial drugs for the treatment of Pseudomonas aeruginosa infection .
