Textbook Question
Chapter 5.2, Problem 1MM
Medical Moment
Q. Antibiotics targeting bacteria have proliferated since the mid-1900s. Antiviral medications are few, and were developed only recently. What alternative control strategy did the medical field employ against viral diseases, starting more than 200 years ago?

In lab, virus
altered so
cannot
reproduce
7.
-Altered cells produce
desired protein
A gene is
inserted into
the virus
6.
Altered cells injected
into patient's body
4.

mixed with
patient's cells
5.
Cells become
genetically altered
1. Follow all the steps in the diagram and then draw it in your observation
notebook.

Applying the terms of science → The following fictional experiment demonstrates the use of the scientific method. Many people in the small Midwestern town of Hootville are stricken with the disease "Buggo." Most of those who get sick recover in seven to nine days. Buggo has been shown to be caused by a bacterium (single for bacteria) called "Gotcha." Antibiotic "X" is a new drug that has been shown to kill Gotcha bacteria in a test tube. Antibiotic X was also found to cure dogs that were sick with Buggo. 3 #m Researchers decided to test the new drug on some of the people in Hootville. They hypothesized that the drug would effectively cure Buggo in humans. They decided that if they gave patients Antibiotic X, the patients would recover more quickly than those who did not take the antibiotic. The researchers prepared tablets containing Antibiotic X. They also prepared a second batch that contained all the same ingredients (inactive ingredients) as Antibiotic X without any…arrow_forwardIntroduction: There’s quite a bit of interest around repurposing extant drugs to treat infections by targeting host pathways that pathogens rely on. Here are a few potential drugs: 1) A drug that inhibits endocytosis, but not phagocytosis. 2) A drug that inhibits degradation of cytoplasmic proteins into smaller peptides, preventing their cycling back into amino acids. 3) A drug used to treat porphyria that reduces the reactivity of heme. 4) A drug that depletes glutathione, a chemical which protects red blood cells against the reactivity of heme. 5) A drug that reduces expression of the ACE-2 protein. Question: Pick a drug and an infection that the drug is likely to be good at treating, or pick an infection and a drug that would most likely make the infection substantially worse. Which drug and pathogen did you pick? Do you think it’ll make it better or worse?arrow_forward
