Antimicrobial activity of latamoxef (moxalactam) against both Bacteroides fragilis and Escherichia coli in an intraperitoneal abscess model

The antimicrobial activity of latamoxef (moxalactam) was examined against Bacteroides fragilis and Escherichia coli individually and in combination in an intraperitoneal tissue capsule animal model during ten days of therapy given at 40 mg/kg/day. Mean peak serum concentration was 32.8 mg/1. Mean capsular latamoxef concentrations during samplings on days three, seven and ten were 1.8 mg/1 for Bact. fragilis, 0.7 mg/1 for E. coli,
