Concept explainers
To determine:
The difference between the terms bactericidal and bacteriostatic in relation to microbial control agents.
Concept introduction:
The adverse effect of antimicrobial agents on microbial cells that lead to their death is known as the mode of action. Agents affect cell targets that inflict damage leading to death of the microbial cell or slow down the
To determine:
An experimental method to test whether a control agent exhibits bactericidal or bacteriostatic effects.
Concept introduction:
To devise an effective treatment for the infectious disease, the determination of antimicrobial agent which is most effective against a specific pathogen is necessary. The mode of action of various types of antimicrobials determines their effect on microbial growth.
