Summary Introduction
Introduction:
When microorganisms can tolerate an amount of antimicrobial drug, which would generally be inhibitory, it isknown as drug resistance. Microbes have characteristic of drug resistance, because they have an incredible genetic versatility and adaptability of bacterial population. The characteristics of antibiotic resistance are either intrinsic or acquired.
