- A bacterium can protect itself against antibiotics in different ways. Describe 4 fundamentally different mechanisms of antibiotic resistance. Discuss if there are any basics differences or similarities between these 4 mechanisms and if so describe these.Describe the difference between broad spectrum and narrow spectrum antibiotics. Describe the pros and cons of both types. Give specific examples of each type of antibiotic and tell what it’s mode of action is.Whether an antimicrobial is broad spectrum or narrow spectrum depends on its mode of action. For the following 2 hypothetical drugs, predict whether they are broad spectrum or narrow spectrum. Explain your reasoning: 4. a. Drug A interferes with peptidoglycan synthesis - b. Drug B interferes with 70S ribosome function- c. Drug C interferes with synthesis of a vitamin –
- A pathogenic bacteria ferments for survival in your patient producing a swollen, dark discolored leg due to muscles degradation and gas-filled distension on the skin. Treatment includes pressurized hyperbaric oxygen. Which of the following apply? None of the statements apply Streptococcus pneumoniae causing community aquired pneumonia. Klebsiella pneumoniae causing cellular degradation in pulmonary tissues Clostridium perfringens causing gas gangrene resulting in myonecrosis by synthesis of acids and gases Staphylococcus aureus producing lipases and proteasesA major problem in fighting pathogenic bacteria is known as the 'antiseptic dilemma'. Explain what this "dilemma" is, why it's a problem, and how antibiotics like penicillin avoid this problem.What is the spectrum of activity for an antibiotic and why would this be important treating infections? Compare and contrast narrow and broad spectrum antibiotics.
- present the chemical mechanism of the HIV protease. Discuss the mode of action of some inhibitors of this enzyme.Why is antibiotic resistance a problem and how can antibiotic resistance be prevented? (List the 7 methods for preventing resistance.)Match each of the descriptions in Column A with the correct panel listed in Column B. Description Panel Resistant bacteria share resistance genes with each other Resistant bacteria survive and reproduce Treatment with methicillin kills nonresistant bacteria Some bacteria carry a mutation that provided resistance to methicillin Predict the possible outcome(s) if the antibiotic tetracycline was applied after panel 4. Check all that apply. O The tetracycline will act as a selective pressure, causing bacteria to mutate in order to survive. O Since the population is resistant to methicillin and not tetracycline, none of the bacteria will survive. O Treatment with an antibiotic will not affect the overall survival of the population. Any bacterium that has a mutation for tetracycline resistance would be able to survive.
- Explain: 1. Pharmacokinetics of Unclassified Antibiotics 2. Pharmacodynamics of Unclassified Antibioticshttp://vlab.amrita.edu/?sub=3&brch=73&sim=1628&cnt=1 Explain how the Kirby-Bauer method relies on diffusion of antibioticsstep 1 Staphylococcus aureus is a bacteria, that is now resistant to commonly used antibiotics, and it is now resistant to the antibiotic methicillin (narrow spectrum beta lactam class). step 2 Describe the physiological mechanism used by individual bacteria to resist the antibiotic listed in above of this Thought Question. For example, the mechanism could be modification of drug, modification of target, prevention of drug penetration, overproduction of target, or target mimicry. (This means that you must choose a strain of bacteria that we know the characteristic of the bacteria that allows the bacteria to be resistant.)
