In vitro susceptibility of Corynebacterium group D2 and Corynebacterium jeikeium to twelve antibiotics.
The in vitro susceptibility of 83 Corynebacterium group D2 strains and 44 Corynebacterium jeikeium strains to 12 antimicrobial agents was determined by an agar dilution technique using Mueller-Hinton agar supplemented with Tween 80 (0.025%). All strains of Corynebacterium group D2 were highly sensitive to fusidic acid, pristinamycin, teicoplanin and vancomycin (geometric mean MICs 0.047, 0.048, 0.338 and 0.396 mg/l respectively). Most of the strains were resistant to other antibiotics tested (ciprofloxacin, erythromycin, gentamicin, lincomycin, rifampin and tetracycline). However, a few strains were highly sensitive (MICs less than or equal to 0.2 mg/l). The overall pattern of susceptibility of 44 strains of Corynebacterium jeikeium was similar; the geometric mean MICs of fusidic acid, pristinamycin, vancomycin and teicoplanin were 0.234, 0.235, 0.557 and 0.652 mg/l respectively.
