9
Q

Describe the criteria for “susceptible”, “intermediate” and “resistant” interpretations in antimicrobial susceptibility testing.

A

Susceptible: isolate can be treated with the standard dose rate for the species and condition
Intermediate: lesser response than above, ensure the drug chosen will be physiologically concentrated at the site OR give at a higher (non-toxic) dose
Resistant: isolate is not inhibited by useable doses

10
Q

Define what a multi-drug resistant organism is.

A

Organism is resistant to at least one antimicrobial agent within 3 or more antimicrobial classes to which the organism is normally susceptible.
