  1. This table shows the minimum inhibitory concentration (MIC) of the indicated antibiotics against N. cyriacigeorgica. The specific susceptible breakpoint of Sulfamethoxazole / Trimethoprim (SMX/TMP) for Nocardia species was ≤2/38 and the specific resistance breakpoint was ≥4/76. The MICs of SMX/TMP for N. cyriacigeorgica were 1/19. Thus, the N. cyriacigeorgica was regarded as sensitive to SMX/TMP
