Chapter 4, Problem 15PS

Interpreting Data A population of bacteria may evolve resistance to a drug over time. Draw a graph that represents such a change. Label the x-axis as “time” and the y-axis as “population size.” Draw a line on the graph that represents how the size of the population might change over time after the introduction of a new antibiotic. Label the point on your line where the new drug was introduced, and then indicate how the population size might change overtime after that introduction.

The Kishony performed a simple but elegant experiment using a “mega-plate.” Which of the following is a fair conclusion that can be drawn from this study? The majority of antibiotic resistance occurs via horizontal gene transfer (HGT) between Actinobacteria Sensitive bacteria may acquire resistance to high concentrations of the antibiotic through many mutations Bacteria will gradually lose resistance to an antibiotic if you plate them on a large enough plate Bacteria will migrate via chemotaxis away from recombinant phage used in phage therapy
What is the best explanation for why a bacteriostatic treatment might be chosen over a bacteriocidal treatment? Bacteriostatic treatments will eliminate all bacteria while bacteriocidal treatments will only eliminate a portion of the bacteria. Bacteriostatic treatments typically have lower toxicity to the host when compared to bacteriocidal treatments. Bacteriostatic treatments will prevent all bacterial growth, while bacteriocidal treatments will permit some bacterial growth. Bacteriostatic treatments are typically more costly than bacteriocidal treatments.
There are concerns about overuse and misuse of antibacterial drugs, and the association of these with increased antibiotic resisstance in bacteria.  Of the following, which best explains this?      Antibiotic exposure directly causes many of bacterial in a population to mutate and develop new antibiotic resistance traits.     If antibiotic use occurs repeatedly in a person, the dosage of the drug needs to be increased to work in a patient’s system because he/she will develop physiological tolerance to the antibiotic.     Exposure to an antibiotic causes bacteria to die or become stronger; stronger bacteria will be better able to cope with additional exposures to any antibiotic drug, eventually becoming immune to all antibiotics.     Antibiotics kill susceptible cells and even a small number of existing resistant bacteria that survive will become the majority of the population that remains, leading to populations that are resistant to this drug.
