Exam 12: Laboratory Methods and Strategies for Antimicrobial Susceptibility Testing

An important factor that plays a key role in a patient's outcome in an infectious disease that is not taken into account by susceptibility testing is

The difference between the serum bactericidal test and the minimum bactericidal concentration test is that

A haze of bacterial growth within a more clearly defined zone of inhibition may be observed when testing

An important requirement for appropriate inoculum preparation in susceptibility testing includes

Enterococcal resistance to ampicillin predicts resistance to

Enterococcal high-level gentamicin resistance predicts resistance to

The serum bactericidal test (SBT) involves

Up-to-date tables that list potential antimicrobial agents to include in batteries for testing against particular organisms or organism groups is published by

The decision to perform susceptibility testing depends on

The concentrations in a broth dilution test that separate the categories of susceptible, intermediate, and resistant are called

In the microdilution broth dilution method, the interpretive criteria for the susceptible, intermediate, or resistant categories are based on

The MIC result recorded in antimicrobial testing can be defined as

The minimal bactericidal concentration (MBC) test involves

Detection of the haze produced by some resistant staphylococci and enterococci against methicillin and vancomycin can best be accomplished by

Bactericidal tests should be performed

Chromogenic cephalosporins are used to test for

The primary goal of antimicrobial susceptibility testing is to

Criteria for establishing a bacterial isolate as clinically significant include

In the disk diffusion method of antimicrobial susceptibility testing, what is the standard agar base medium for testing most bacterial organisms?

Staphylococcal resistance to oxacillin is used to determine and report resistance to
