In vitro susceptibility of nonfermenting Gram-negative rods to meropenem-vaborbactam and delafloxacin

Meropenem-vaborbactam and delafloxacin activities were not assessed against spp. ( ), complex ( ) and ( ). A total of 106 , 57 and 100 were tested with gradient diffusion test of meropenem-vaborbactam, delafloxacin and comparators. Meropenem-vaborbactam MIC were 4 μg/ml for , 1 μg/ml for , 2 μg/ml for and , and 32 μg/ml for . Delafloxacin MIC were 4 μg/ml for , 0.25 μg/ml for and , 2 μg/ml for , and 0.5 μg/m for . meropenem-vaborbactam MICs were fourfold lower than meropenem for 28.3% , 77.2% , 53.8% and 77.2% . Meropenem-vaborbactam and delafloxacin are active against and .
