Question
Chapter 10, Problem 1CT
Summary Introduction
To determine:
The reason that why cocktail of antimicrobial agents is more effective than a single agent.
Introduction:
The spectrum of action determines the range to which a drug could act upon the pathogen. A drug could be effective against a 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.
Summary Introduction
To determine:
The factor which a physician is trying to prevent by prescribing several drugs at once.

Let’s say there are two closely related viruses, let’s call them Guernsey virus and Micro virus. These two viruses only infect epithelial cells. Their surface antigens are sufficiently similar that there are a number of shared epitopes between the two viruses. Choose one of the following:
A) If you get infected and successfully recover from one virus, it’s quite possible that you’ll have neutralizing antibodies against the other.
B) If you get infected and successfully recover from one virus, you’ll still be susceptible to the other one because the antigens aren’t exactly the same.
C) If you get infected and successfully recover from one virus, it’s likely that getting infected with the other virus will be worse because of the common phenomena of antibody-dependent enhancement.
D) Not enough information has been given.
