If the MIC or zone size is interpreted as intermediate using the latest CLSI tables
A) the clinical interpretation of the result is that the patient's infecting organism should respond to therapy with that antimicrobial agent using the dosage normally recommended for that type of infection and that species.
B) the patient's infecting organism is unlikely to be inhibited by the usually achievable concentrations of the antimicrobial agent based on the dosages normally used with that drug.
C) the patient's infecting organism is likely to require the maximum amount of antimicrobial or more than can be achieved and for which the clinical response is likely to be less than with a susceptible strain.
D) None of the above

When an MIC or zone size is interpreted as intermediate, it suggests that the infecting organism may be inhibited by the usually achievable concentrations of the antimicrobial agent when using the maximum recommended dosage. This implies that the organism's susceptibility to the antimicrobial is borderline, and achieving effective treatment may require higher doses or concentrations, potentially leading to a less favorable clinical response compared to a susceptible strain.
