Which statement accurately describes the process of determining antimicrobial susceptibility for a bacterial pathogen?
Guidelines are followed to determine which specific bacterial isolates require susceptibility testing based on their clinical significance.
Which of the following statements is true regarding the predictability of antimicrobial susceptibility patterns among different bacterial groups?
Gram-negative bacilli, enterococci, and staphylococci often exhibit unpredictable susceptibility patterns, necessitating susceptibility testing.
Which of the following methods is used to determine the minimum concentration of an antimicrobial agent required to inhibit the growth of a bacterial isolate?
Broth dilution method
In the disk-diffusion method for antimicrobial susceptibility testing, what does the absence of growth around a disk indicate?
The microorganism is sensitive to the antimicrobial agent in the disk.
Which organization publishes and regularly updates the standards for antimicrobial susceptibility testing methods used in clinical laboratories?
