Chapter 10, Problem 3MC
Summary Introduction
Introduction:
Antimicrobial drugs are selectively toxic against microbes, so that it does not cause any harm to humans. To devise an effective treatment for the infectious disease, the determination of antimicrobial agent, which is most effective against a specific pathogen, is necessary. Various tests are there to test the effectiveness of antimicrobials like minimum inhibitory concentration test, diffusion susceptibility tests, and minimum bactericidal test.

A factor in the zone of inhibition size on the Kirby-Bauer plate is:
a. amount of medium placed on the plate
b. rate of diffusion of the drug used
c. stage of growth of the microbe placed on the plate
d. all of these
Selective toxicity of a drug refers to
