Clinical Distribution and Drug Resistance of Pseudomonas aeruginosa Isolates / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To investigate the clinical distribution and drug resistance of clinical Pseudomonas aerugilosa isolates,and offer reasonable experimental data for clinical therapy.METHODS P.aerugilosa was identified by ATB Expression system,and its drug resistance was determined by Kirby-bauer and ATB Expression method.RESULTS The main departments in which frequently P.aerugilosa infection accurred were Intensive Care Unit(41.2%) and Respiration Departments(19.3%).The common site of P.aerugilosa infection was respiratory tract(68.2%).The sensitive rate of P.aerugilosa to polymyxin E and cefoperazone/sulbactam was the highest(95.1% and 91.4%),while to meropenem and imipenem was 77.5% and 70.6%.The highest resistant rate of P.aerugilosa to trimethoprim/sulfamethoxazole,ampicillin/sulbactam was 97.1% and 95.1%.The resistunce to ciprofloxacin,ticarcillin and piperacillin,were 64.9%,63.3% and 56.3%.CONCLUSIONS P.aeruginosa is major pathoge in our hospital.It is important to select antibiotics correctly according to the results of susceptibility tests.
