Question
Chapter 9, Problem 2Q
Summary Introduction
To explain:
The reason why all cells in a population do not die instantaneously when exposed to an antimicrobial agent, even when they are of a single species.
Introduction:
Antimicrobial agents are described as the substances that have the ability to destroy or inhibit microbial growth. Antimicrobial agents used in the treatment of helminthic, protozoan, fungal and viral diseases are grouped as anthelminthic, antiprotozoal, antifungal, and antiviral drugs, respectively. The aim of antimicrobial strategies is to find “new targets in the microbial cell” and “custom-designing antimicrobials”.
