Abstract:
OBJECTIVE To investigate the antibacterial activity of cefoperazone/sulbactam to Gram-negative bacilli in vitro.METHODS Gram-negative bacilli were isolated from various clinical specimens in our hospital from Jan 2004 to Dec 2007,screened by Gram-staining and oxidase test.The strain identification and the antimicrobial susceptibility test were determined by VITEK-60 Full Automated Microbiology Analyzer and slip diffusion method,respectively.The results of the survey were retrospectively reviewed.RESULTS The resistance rates of Enterobacteriaceae to cefoperazone / sulbactam were very low,the rates of Escherichia coli,Klebsiella pneumoniae and Enterobacter cloacae were 6.9%,9.2%and 12.9%,respectively;and the rates of Acinetobacter baumannii,Chryseobacterium meningosepticum,Pseudomonas aeruginosa,Stenotrophomonas maltophilia and Burkholderia cepacia were 7.7%,8.1%,20.4%,21.5% and 34.1%,respectively.CONCLUSIONS The antimicrobial activity of cefoperazone/sulbactam to Enterobacteriaceae and non-fermentation bacteria(A.baumannii,Ch.meningosepticum) is strong.The resistant rate of other Gram-negative bacteria to cefoperazone/sulbactam is less than 40 percent.In the treatment of infection caused by Gram-negative bacilli,cefoperazone/sulbactam has a very good prospect.
