Abstract:
OBJECTIVE To know the antibacterial activity of cefotaxime/sulbactam against 4 kinds of Gram- negative bacilli in vitro in general clinics. METHODS By double-disk test to detect the ESBLs of Escherichia coli and Klebsiella pneumoniae and the metallo-?-lactamase of Pseudomonas aeruginosa and Acinetobacter baumannii. And all the tested bacilli were tested by 14 kinds of general antibacterial drugs through K-B experiment. RESULTS Fifty one of 164 Enterobacteriaceae strains were ESBLs positive, including 23 E. coli strains with positive rate of 26.3% and 28 K. pneumoniae strains with positive rate of 35.9%. The metallo-?-lactamase was produced in 33 of 85 P. aeruginosa strains and the positive rate was 38.8%, and none in A. baumannii. The result showed cefotaxime /sulbactam was very sensitive to Enterobacteriaceae, no matter it had enzyme or not. These drugs had a special high sensitivity to ESBLs producing E. coli and K. pneumoniae, and their sensitivity rate was 87.0% and 89.3%. The sensitivity rate to P. aeruginosa, produced enzyme or not was 56.7% and 92.3%. CONCLUSIONS Cefotaxime/sulbactam has a powerful antibacterial activity against 4 kinds of Gram-negative bacilli in vitro in general clinics, especially to the infection caused by ESBLs-producing or metallo-?-lactamase-producing bacteria, and can be taken as the preferred drugs.
