Factors affecting the in vitro activity of cefoperazone against the Bacteroides fragilis group.

V L Sutter, Y Y Kwok.   

Abstract

The in vitro activity of cefoperazone against 32 strains of bacteria of the Bacteroides fragilis group was determined on four media by using a variety of test parameters. Lower mean minimal inhibitory concentrations (MICs) were obtained on Mueller-Hinton blood agar and supplemented brain heart infusion agar than were obtained on brucella laked blood agar or Wilkins-Chalgren agar. Higher MICs were obtained with 6-h inocula than with 24-h inocula, and slightly higher MICs were obtained with tests read at 48 as compared with 24 h. Conducting tests in an anaerobic glove box had little effect. The greatest differences in mean MICs were seen with inoculum densities of 10(4) and 10(5) colony-forming units.
