Abstract
To elucidate the clinical characteristics of imipenem-resistant Acinetobacter baumannii causing nosocomial infections in the First Affiliated Hospital of China Medical University, 34 isolates genotyped by pulsed-field gel electrophoresis (PFGE)were collected from January 2007 to December 2007. Isolates were most commonly found in the ICU and burn ward in this study, accounting for 47.06% (16 isolates) and 26.47% (9 isolates) of the total isolates, respectively. For the most patients infected by A. baumannii, three to seven risk factors generally existed. But some factors (including diabetes mellitus, chronic respiratory diseases and tumor) were mostly negative for those patients. The clinical data obtained suggested that the three clinical risk factors may take little action in the nosocomial infection caused by A.baumannii in the hospital. As for the use of antimicrobial, different types were selected before the occurrence of the most infections. This may be an important factor leading to the multi-drug resistance.
Key words: Acinetobacter baumannii, clinical characteristics, epidemiological description, risk factors.
