title: Effects of differences in media and methods on MIC values for anaerobes.
abstract: In vitro susceptibility of Bacteroides fragilis isolates to cefoxitin at the breakpoint of 32 micrograms/ml varied little when tested by eight different methods. We found that broth disk elution results were difficult to read and interpret and did not correlate with other methods.
