Nosocomial Infection and Antimicrobial Resistance of Pseudomonas aeruginosa among Neonates / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To investigate the distribution of drug resistance of Pseudomonas aeruginosa(PAE) among neonates and analyze the characteristic of the PAE infection.METHODS API system was used for the identification of 131 PAE clinical isolates and the resistance to 17 kinds antibiotics was determined by K-B method.RESULTS Most of 131 strains were isolated from sputum(42.0%) and gastric juice(32.8%).All strains were mainly isolated from neonate intensive care unit(NICU).The sensitivity to amikacin,levofloxacin,ofloxacin,ciprofloxacin,piperacillin/tazobactam,cefoperazone/sulbactam,imipenem and meropenem was respectively over 70.0%.PAE was inferior sensitivity to piperacillin,mezlocillin,cefoperazone,ceftriaxone,ceftazidime and aztreonam.CONCLUSIONS PAE is one of the most common pathogens causing nosocomial infection especially for neonates.Its susceptibility to antibiotics showed multidrug resistance.In order to reduce or prevent the occurrence of resistant isolate,we should rationally choose and use antibiotics combining with trait of neonate.
