Surveillance of Antimicrobial Resistance and Classification in Non-fermenting Bacteria Isolated from Lower Respiratory Tract for 3 Consecutive Years / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To investigate the distribution and resistance of non-fermenting bacteria isolated from our hospital and offer the basis for the treatment of bacterial infection.METHODS Totally 2177 strains of non-fermenting bacteria were isolated from clinical sputum samples between Jan 2006 and Dec 2008.All of the isolated bacteria were identified with API identified test(API Inc,France) and Kirby-Bauer(K-B) test used for the antibiotics susceptive test.RESULTS From them the most common bacteria were Pseudomonas auruginosa(34.9%),followed by Acinetobacter baumannii(28.4%) and Stenotrophomonas maltophilia(11.4%).These bacteria had various resistances to the tested antibiotics.CONCLUSIONS Non-fermenting bacteria have high isolate rate and multi-antibiotic resistance,so antibiotics should be correctly used under the guidance of antibiotic susceptibility test.
