Which of the following is not one of the objectives of the antibiotic resistance study?   A. Distinguish between a virus and a bacteria   B. Distinguish between broad spectrum and narrow spectrum antibiotics   C. Distinguish between susceptibility and resistance   D. Anderstand the advantages of the Kirby-Bauer method versus the Disk-Diffusion method   E. All of these are objectives

The drugs you evaluated in your disc susceptibility tests have different potencies (see table C1; disc content). Which ONE of the following options, based on the laboratory data alone, is the most approapriate in the treatment of a patient with a UTI ? Select one: A. All the above drugs (A, B, C and D) could be considered B. Trimethoprim (zone size 30 mm)   C. Ampicillin (zone size 25 mm) D. Amoxicillin (zone size 15 mm) E. Cephalexin (zone size 25 mm)

step 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.)

The development of antiviral therapies offers unique challenges. Describe why many existing antiviral drugs cause severe side effects in patients?   It is often difficult to differentiate between viral and bacterial diseases with similar symptoms. In order to ensure proper diagnosis, symptoms should be observed for which two characteristics?

which of the following definitions is not technically correct? a. broad spectrum - effective against many different types of microbes b. bacteriostatic - prevents microbes from growing c. antibiotic - microbial or synthetic product that kills or inhibits growth of microbes. d. all of the above are correct

. Susceptibility of the bacteria will be determined by observing for the production of plaques. Describe how these plaques are formed. Would the different strains/species of bacteria be susceptible to bacteriophage T2? Explain why b. How does a viral plaque compares to a bacterial colony? c. Which organism is identified by the use of bacitracin? What does the absence of bacterial growth around the bacitracin disc indicate?

A plaque assay is an effective way to determine the concentration of lysogenic phage in a solution. A. True B. False

1) COVID-19 b. Do you think that complete lockdowns have worked? What are some of the direct and indirect impact of lockdowns  c. Do the mask really work? Does the type of mask matter, if so, how? d. Why is it that some people (vaccinated and even unvaccinated ) never have contracted COVID-19 and/or tested positive for COVID-19
