In vitro activities of doripenem and six comparator drugs against 423 aerobic and anaerobic bacterial isolates from infected diabetic foot wounds

Against 182 anaerobe and 241 aerobe strains obtained from diabetic foot infections, doripenem was the most active carbapenem against Pseudomonas aeruginosa (MIC(90), 2 microg/ml), more active than imipenem against Proteus mirabilis, and ertapenem was more active against Escherichia coli and Klebsiella spp. The MIC(50) and MIC(90) values were < or =0.125 microg/ml for methicillin-sensitive Staphylococcus aureus and all streptococci and 0.25/1 for Bacteroides fragilis.
