Identification and Antimicrobial Susceptibility of 250 <i>Bacteroides fragilis</i> Subspecies Tested by Broth Microdilution Methods

Abstract

Broth dilution antimicrobial susceptibility tests and biochemical identification of Bacteroides fragilis subspecies were performed by micromethods, yielding results within 48 to 72 h of isolation. The subspecies had similar minimal inhibitory concentration end points.
