Question
Chapter 25, Problem 15TYU
Summary Introduction
To determine: The way in which the use of antibiotics imposes selective pressure on bacteria.
Introduction: A drug could be effective against a wide range of pathogens or to a narrow range of pathogens. The spectrum of action determines the range to which a drug could act on pathogens. Pathogens sometimes acquire resistance to one or more than one type of antibiotics.

- What is a relevant biological process that can be used to illustrate the answer to the question: What are the risks associated with antibiotics? i.e. What is the underlying biology that addresses 'What are the risks associated with antibiotics?'arrow_forwardDescribe one adaptation a bacteria could have that would allow it to be resistant to an antibioticarrow_forwardThe 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_forward
- (T3) 6. Why is overuse of antibiotics resulting in more antibiotic-resistant strains of bacteria to evolve ? - [ ] The antibiotic becomes less potent over time leading to resistance - [ ] The normal flora of the patient can no longer to outcompete the pathogen - [ ] The antibiotics create the mutations that result in resistant organisms - [ ] The patients begin to have less side-effects from the antibiotics - [ ] The antibiotics provide the selective pressure for resistancearrow_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_forwardWhy can bacteria undergo rapid evolutionary change? a) Bacteria pass through numerous bottlenecks b) Bacteria mutate at high rates c) Bacterial populations are large and can reproduce quickly - 8:23 varrow_forward
- If you were developing a new “broad-spectrum” antibiotic to kill a widevariety of bacteria, which cell structures and pathways would you target?Which of those targets also occur in eukaryotic cells, and why is thatimportant? How would your strategy change if you were designing a new“narrow-spectrum” antibiotic active against only a few types of bacteria?arrow_forwardThe 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 therapyarrow_forwardDescribe two events occurs when antibiotics are present or not and microbes become newly resistant to a drug?arrow_forward
- How might the heavy-handed use of antibiotics result in the increase of antibiotic-resistant cells in bacterial populations?arrow_forward13) A certain bacterial colony originated from the division of a single bacterial cell. Each cell in this colony will most likely A) express adaptations unlike those of the other cells B) synthesize the same proteins and enzymes C) have a resistance to different antibiotics D) replicate different numbers of genesarrow_forwardIn the mid-1990s, researchers discovered an enzyme in HIV called protease. Once the enzyme's structure was known, researchers began developing drugs that fit into the active site and blocked it. This strategy for stopping HIV infections is an example of what phenomenon?
