riefly describe any THREE CATEGORIES (three modes of action) of antibacterial drugs.  Make sure to tell how they work and how bacteria have become resistant to them.

Describe some of the special strategies of antimicrobial therapy.

What is selective toxicity in the context of antibiotic chemotherapy? Support your answer with examples.

Explain how bacteria can become resistant to ampicillin. Be sure to mention the following terms: peptidoglycan, beta lactamase, transpeptidase, beta lactam.

Which of these antibiotics would do the best job as a broad spectrum antibiotic?

Compare and contrast broad spectrum and narrow spectrum antibiotics and explain how they differ.

Suggest a possible mechanism for how a microbe that becomes resistant to an antimicrobial chemical can transfer that to another microorganism, and also transfer resistance to antibiotics in the process.

Name two classes of antibiotics with different pharmacophores on them and briefly describe their mechanism of action with particular emphasis on the chemical reactions that cause their medicinal effects

Which antimicrobial agents have the narrowest spectrum of action? antivirals antifungals beta-lactams sulfanilamidesBottom of Form Penicillin is a narrow spectrum antibiotic because it only affects bacteria with mycolic acid in its cell wall, such as Mycobacterium tuberculosis. it only affects viruses it only affects Gram-negative organisms it only affects Gram-positive organismsBottom of Form Which of the following antibiotics might be destroyed by beta-lactamase enzymes? amphotericin B and ciprofloxacin streptomycin penicillin ciprofloxacinBottom of Form Which is incorrect about how the pharmaceutical industry has discovered drugs over the past 100 years? The process of discovery has involved custom-designing chemical compounds that we know will bind to target enzymes. The process of discovery has involved screening for chemicals that are toxic to bacteria while being less toxic to human cells. The process of discovery has involved screening thousands of randomly…

describe four modes of action of antimicrobial agents, and give a specific example of how each works
