Question
Chapter 10, Problem 6Q
Summary Introduction
To determine:
A different cellular target for antibiotic action than the ones given in the chapter.
Introduction:
Antimicrobial strategy revolves around realizing the necessary metabolic activities of microbes, followed by using methods to remove or disrupt their basic requirements for survival. The commonly used antimicrobials are categorized according to their target of metabolic action in infectious microbes.

The question below is one question I just separated the question marks
1) How are antibiotics, as a class of drugs, unique?
2)How does this facilitate resistance?
3)How are antibiotics misused?
Methicillin-resistant Staphylococcus aureus (MRSA) is one of the most dangerous organisms that
can be encountered in the health care setting. MRSA is often resistant to more than one
antibiotic.
1. What does it mean to say that S. aureus is resistant to methicillin?
2. What antibiotic would you choose to combat this micro-organism?
3. What are some clinical consequences for the patient infected with MRSA?
