Step by step
Solved in 2 steps
- Which of the following groups of antimicrobial drugs selectively targets bacterial cell wall synthesis? beta-lactams quinolones sulfonamides polymyxins phenolsWe have many antimicrobial drugs to treat bacterial infections, but very few for viruses. Why is it so difficult to treat viral infections? Hint: What would the targets for the drugs be?Penicillin uses which mechanism of antibiotic action against bacterial cells? Inhibition of cell wall synthesis Inhibition of protein synthesis Alteration of cell membranes Inhibition of nucleic acid synthesis
- Bacteria exhibit drug resistance only by genetic means. OPTIONS: True FalseSome antibiotics are effective against only a limited range of organisms. What is a term you learned in the virtual lab that is used to describe this phenomenon and describe what it means.Why do most antibacterial drugs not destroy human cells?
- 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…Expand on some of the consequences to the good bacteria when using anti-bacterial agents.Identify a correct statement about tetracyclines. Multiple Choice They have a narrow antibacterial spectrum. They are bactericidal in nature. They bind irreversibly to bacterial ribosomes to inhibit bacterial protein synthesis. Their widespread use has allowed the emergence of bacterial resistance.
- Explain how bacteria can become resistant to ampicillin. Be sure to mention the following terms: peptidoglycan, beta lactamase, transpeptidase, beta lactam.See picture-- match microbial drug to its action. There can be more than one action per drug.list 3 different mechanisms of antibacterial drugs. Example: acting on cell wall, cell membrane, etc
