Differences Among Nocardia spp. in Susceptibility to Aminoglycosides and β-Lactam Antibiotics and Their Potential Use in Taxonomy

Abstract
Using disk diffusion and agar dilution methods, 109 clinical isolates of Nocardia were tested against 10 antimicrobial agents. A species difference in susceptibility was noted for cefamandole, carbenicillin, gentamicin, and kanamycin. These differences in susceptibility may be of use taxonomically as well as having some potential use clinically.
