ABSTRACT
Objective To understand the clinical characteristics of Acinetobacter baumannii infections in elderly patients in intensive care unit (ICU)and investigate its drug susceptibility. Methods Bacterial identification was carried out by VITEK?32 automatic micro?analyzer(Bio?Merieux Company of French). Data processing was performed with WHONET5.6 software. Results Totally 259 strains of Acinetobacter baumannii were isolated from 220 infected elderly patients. The detection rate of Acinetobacter baumannii was 71.43%(185 strains),13.13%(34 strains), 6.18%(16 strains )and 9.26%(24 strains)from sputum,drainage fluid,blood and other specimens,respectively . Drug resistance of Acinetobacter baumanniito antibiotics was relatively high. Resistance to tigecycline of Acinetobacterbaumanniistrains was the lowest(0%?23.38%)while the sus?ceptibility was the highest(70.13%?80.85%)in all kinds of antibiotics in this study. Conclusion Acinetobacter baumannii varied in drug resis?tance to different antibiotics. It is necessary to choose susceptible antibiotics for clinical anti?infection treatment on the basis of in?vitro antibiotics sus?ceptibility testing for isolated strains from local regions.
