Textbook Question
Chapter 17, Problem 4WIO
If you were developing a new "broad-spectrum" antibiotic to kill a wide variety of bacteria, which cell structures and pathways would you target? Which of those targets also occur in eukaryotic cells, and why is that important? How would your strategy change if you were designing a new "narrow-spectrum" antibiotic active against only a few types of bacteria?

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.
Engineered bacteria are commonly used and cultured in pharmaceutical laboratories to produced drugs like insulin. However, during one instance, with the desire to increase the rate of insulin production, one scientist tried to modify the process and put another substance (chemical x) in the growth medium which is chemically almost the same to the substance (chemical x’) normally put in the medium. After which, the scientist found out that the amount of insulin produced in the medium decreases as compared to the normal production. Again, within the context of our discussion, explain the possible reason for the observed result.
Why do bacteria that are not genetically resistant to antibiotics die out when exposed to antibiotics?

- The discovery and mass-production of antibiotics has triggered a revolution in medicine, decreasing hospitalization times, shortening the course of diseases, and ultimately increasing peoples' lifespans. However, soon after the first major antibiotic, penicillin, was put into widespread use around 1940, people soon found that some bacteria were tougher to kill, which were the first signs of antibiotic resistance in bacteria. Over the years bacteria have been able to develop resistance against many different types of antibiotics, and some bacteria such as methicillin-resistant Staphylococcus aureus (MRSA) is resistant to almost every antibiotic in use today. Antibiotic resistance has become so severe that in 2014 the World Health Organization published a report that speculated of a "post-antibiotic era" where antibiotics were no longer a main method of disease treatment. In this week's forum, please read summary of the World Health Organization's report (linked here and in the…arrow_forwardAntibiotic resistant bacteria have become a major concern for many public health officials. Widespread use of antibiotics has created an evolutionary pressure on infectious bacteria to develop immunity to these medications. The result is an increase in antibiotic resistant microbes, particularly in settings where antibiotics are commonly used, such as hospitals. One strategy public health officials have devised to counteract these infectious microbes is "antibiotic cycling” where specific antibiotics are withdrawn from the market for a period of several years, then reintroduced as another antibiotic is withdrawn. How would this strategy help limit antibiotic resistance? A. It is impossible for a bacterium to maintain resistance to two antibiotics at once B. When a given antibiotic is not in use, it is an evolutionary disadvantage to carry the unneeded gene C. If a specific antibiotic is removed from the market it is possible to substitute with a related antibiotic such as…arrow_forwardBacterial species that are harmful, as well as others that are beneficial, are found living in the human body. To slow the rate of developing antibiotic resistance in bacteria, physicians are being encouraged to use "narrow-spectrum" antibiotics- those that target only a few bacterial types. How can the information learned by antibiotic sensitivity testing be used by physicians who must choose antibiotics that inhibit the growth of bacteria causing disease but that do not interfere with beneficial bacteria?arrow_forward
