MICs of M33-L and M33-D for different bacteria species and strains.

aM33 antimicrobial activity was evaluated on reference strains and clinical isolates (mostly with an MDR phenotype). Relevant resistance phenotypes and resistance determinants are indicated. Resistance phenotypes: FQr, resistant to fluoroquinolones; AGr, resistant to aminoglycosides (gentamycin, amikacin, and/or tobramycin); ESCr, resistant to expanded-spectrum cephalosporins; NEMr, resistant to carbapenems (imipenem and/or meropenem); MRr, methicillin-resistant; VANi, vancomycin-intermediate. Resistance determinants: ESBL, extended spectrum β-lactamase; MBL, metallo-β-lactamase.
