Legend. S: Susceptible, Increased Exposure (A microorganism is classified as increased exposure and susceptible when there is a high probability of therapeutic success because exposure to the agent is increased by adjusting the dosing regimen or by its concentration at the site of infection) R: Resistant (A microorganism is classified as resistant when there is a high probability of therapeutic failure even with increased exposure) (http://www.eucast.org/clinical_breakpoints/, accessed on 3 May 2021).
