Which of the following best describes the mechanism of action of the antibiotic streptomycin? A. it disrupts protein synthesis in resistant bacteria. B. Streptomycin inhibits cell wall synthesis in all bacterial species. C. Streptomycin creates mutations in bacteria which cause them to become resistant. D. It disrupts protein synthesis in nonresistant bacteria.
Why are encapsolated bacteria generally more pathogenic than un-capsolated strains. a. Because capsule allows the organism to hide in the body of the host. b. because the capsule causes the phagocyte to mutate c. because the capsule protects bacteria from host immune cells d. because the capsule kills the phagocytes e. because the capsule stimulates a potent immune response in the host.

Suppose you do this test on a hypothetical Staphylococcal species with the antibiotics penicillin and tetracycline. You record zone diameters of 20mm for the tetracycline disc and 25mm for the penicillin disc. Which antibiotic would be most effective against this organism? What does this tell you about comparing zone diameters to each other and the importance of the interpretive chart?
Which of the following BEST describes an agent that is bacteriostatic? A) It suspends bacterial synthesis of Tranexamic Acid. B) It kills the bacteria by destroying its cell wall. C) It zaps the bacteria with static electricity. D) It suspends bacterial growth.
Describe the interactions of Agrobacterium tumefaciens with its host plant. Why is this plant pathogen useful for biotechnology?
Give two reasons why bacteria are becoming more and more resistant to antibiotics.
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 of the Antibiotic resistance study
propose a hypothesis regarding the organisms (staphylococcus, escherichia, pseudomonas, and bacillus) that will be resistant to the most disinfectants, and why? if the hypothesis is supported, what specific experimental results will be observed? what would be the independent and dependent variable? zone size, disinfectant type, colony count
Why are Pseudomonas aeruginosa infections difficult to treat? A. Because they form biofilms, which are difficult for antibiotics to penetrate. B. Because they have a special endotoxin that degrades many antibiotics. C. Because we do not have any antibiotics that target P. aeruginosa. D. Because they are gram-positive bacteria, which are harder to treat.
