Abstract:
Objective To report and analyze the changes of bacterial species and resistance to antibiotics in the burn center from 1993 to 2007. Methods Bacterial identification and susceptibility test were performed by applying VITEK-AMS system. Results A total of 4 762 strains were isolated,including 60 species of 21 genera. Pseudomonas aeruginoasa (PA) was the most common organism (36. 79%), and its isolating rate was 36. 79%; in 2006, the highest isolating rate of PA was 51.6%.The isolating rate of Staphylococcus aureus was 14.09 %, next to that of PA; followed by Enterococci faecalis, Acinetobacter, Escherichia coli, Enterococci faecium, Enterobaeter cloacae and Staphylococ-cus epidermidis, and the 8 kinds of germs shared 78. 12% of bacterial isolates (3 746/4 762). The an-tibiotic resistance rate of Pseudomonas aeruginosa was increasing year by year; it was vitally resistant to the third generation eephalosporins and imipenem. Conchtsion The predominant species of bacteria from burn center is Pseudomonas aeruginosa, and RA isolates are multi-resistant to antibiotics. The i-solating rates of Enterococeus faeealis and Acinetobacter are increasing. This implied the importance of rational and correct use of antibiotics about control of burn infections as well as avoidance of abusage of broad-spectrum antibiotics.
