title: In vitro susceptibility of Mycobacterium fortuitum to amoxicillin or cephalothin in combination with clavulanic acid.
abstract: The comparative in vitro activity of cefoxitin, cephalothin, amoxicillin, and clavulanic acid in combination with the latter two agents against 13 isolates of Mycobacterium fortuitum was evaluated by agar dilution susceptibility testing. Amoxicillin was more active than cephalothin but less active than cefoxitin against the strains tested. Clavulanic acid in combination with these beta-lactams usually improved the activity by one or two dilutions compared with the beta-lactams alone.
