Chapter 12, Problem 14TF
Summary Introduction
Concept introduction:
Spectrum of action determines the range to which a drug could act upon the pathogen. A drug could be effective against wide range of pathogens or to a narrow range of pathogens. The pathogens sometimes acquire resistance to one or more than one microbial agents. Multiple drug resistance and cross resistance are the types of resistance seen in pathogens against antimicrobial drugs. Microbes have characteristic of drug resistance because they have incredible genetic versatility and adaptability of bacterial population.
