Standardization of Antimicrobial Susceptibility Testing Optimizes Bacterial Growth So Inhibition

Multiple Choice

Standardization of antimicrobial susceptibility testing optimizes bacterial growth so inhibition of growth can be attributed to the antimicrobial agents tested and results are accurate,reproducible,and consistent regardless of the microbiology laboratory performing the test.Which of the following incubation conditions are used for common (i.e. ,nonfastidious) bacterial isolates using manual techniques?

A) 16 to 20 hours,ambient temperature,5% to 7% CO₂
B) 16 to 20 hours,35°C,ambient air
C) 20 to 24 hours,ambient temperature,5% to 7% CO₂
D) 20 to 24 hours,35°C,ambient air
