Objective To explore the distribution and antibiotics resistance of non-fermenting bacteria in intensive care unit to guide rational application of antibiotics in clinic.Method The non-fermenting bacteria isolated from sputum specimens of patients in intensive care unit from 2008 to 2009 were identified and their drug resistance were analyzed.Result A total of 4 273 strains of non-fermentating bacteria were isolated,representing an isolation rate of 38%,The dominant 4 strains were Pseudomonas aeruginosa(44.09%),Acinetobacter baumannii(27.64%),Stenotrophomonas maltophilia(10.58%) and Burkholderia cepacia(5.99%).High drug resistance to common antibiotics,excluding from β-lactamase inhibitor compound for instance cefoperazone/sulbactam,was revealed in the four species of non-fermenting bacteria.Conclusion Non-fermenting bacteria isolated from hospitalized patients in intensive care unit show higher isolation rate and multidrug resistance.Therefore,pathogenic bacteria identification and antimicrobial susceptibility test should be strengthened to instruct antibiotics properly in clinic.
