ABSTRACT
OBJECTIVE To investigate the distribution and drug resistance of Pseudomonas aeruginosa.METHODS All specimens isolated and cultured from patients in our hospital were identified by using the automatic microorganism analyzer WalkAway-40,Dade Behring made in America,and bacteria′s drug susceptibility test and identifications were performed on strains using NC21 Microscan Panel.RESULTS From sixty-two strains of P.aeruginosa 36 strains were isolated of sputum.The resistance rate to the third generation of cephalosporins cefotaxime and ceftriaxone was 55.6% and 47.5%,respectively.The resistance rate to the other ?-lactamases antibiotics such as ceftazidime was 7.5%,piperacillin/tazobactam 11.0%,cefepime 14.8% and penicillin was 30.0%,the ratio of resistance for imipenem was 20.0%,the lowest one was amikacin(4.6%).CONCLUSIONS P.aeruginosa is one of the main bacteria in the lower respiratory tract infection.The drug-resistant mechanism of P.aeruginosa is very complex,including multidrug resistance characteristics,and it is originally resistant to several antibiotics.To avoid being produced ?-lactamases and result in resisting drug widely,the antibiotics should be selected according to low drug-resistant rate and taking into account sufficiently its drug resistance mechanism in the treatment of P.aeruginosa infection.
