Antibiotic – intrinsic resistance
Microorganisms are only listed as “intrinsically resistant” to an agent (or group of agents) when a vast majority of wild-type isolates exhibit MIC values that are so high that the agent should not be considered for either therapy or clinical susceptibility testing (EUCAST). Enterobacterales & Aeromonas Enterobacterales and Aeromonas are intrinsically resistant to benzylpenicillin, glycopeptides, […]
