Distribution of A.baumannii infections and drug resistance in Ningbo

Objective To investigate the distribution and antibiotic resistance of A.baumannii during the last five years in our hospital,the basis for the reasonable clinical use of antibiotic was provided to doctor. Methods The strains of A.baumannii isolated from clinical specimens during 2009-2013 were analyzed by VITEK-32 system, the antibiotic resistance was analyzed by WHONET5.4 software. Results A.baumannii strains were mainly isolated from sputum, accounting for 77.3%; the majority of the strains were isolated from ICU,accounting for 42.3%; the resistance rates of A.baumannii to antibiotics appeared increasing, and over 70%except cefoperazone-sulbactam and imipenem. Conclusion A.baumannii is the major pathogen, and detection rate of A.baumannii is very high, antibiotic resistance status of A.baumannii is very serious. The management of antibiotic application should be strengthened, and the occurrence and prevalence of antibiotic resistant bacteria should be strictly controlled to prevent outbreak and epidemic of nosocomial infection.
