Homework Answers
The microbes with enhanced morbidity and mortality due to multiple mutations causing high levels of resistance to antibiotics are referred as superbugs. The superresistant microbial strains acquired increased virulence and enhanced transmissibility in various ways. Most of the bacteria become resistance to antibiotics by genetic mutations and acquiring resistance from another bacterium. The mutation in the target gene can eliminate effect of antibiotic and develop resistance. The natural process of transfer of resistance genes through ‘conjugation’ can develop antibiotic resistance.

The use, overuse, and abuse of antibiotics are accredited with creating antibiotic-resistant strains of bacteria. Explain how this relates to natural selection. Are there things that you can personally do to reduce your risk or even to reduce the spread of these dangerous microbes?

Explain why the overprescription of antibiotics by doctors, or the overuse of everyday soaps containing antibiotics, can be a health risk. O The overuse of antibiotics or antibiotic soaps can be a health risk because the repeated exposure to antibiotics can damage human cells. When antibiotics are overused, the repeated exposure triggers mutations in the bacteria that result in resistance. Resistant bacteria will then survive and multiply, reducing the effectiveness of the antibiotic treatment in the future. When antibiotics are...

a everytime an antibiotic is used in humans or animals,there is a risk that antibiotics resistance will be become more common in bacteria. use what you know about natural selection and evolution to explain how bacteria become resistant to antibody. b. what effect would transduction, transformation and conjugation have on the amount of antibiotic resistance in bateria? explain.

2. Researchers in Israel have developed a novel method of restoring antibiotic sensitivity to resistant bacteria, according to a study in the journal Applied and Environmental Microbiology. The process could eventually be used to fight hospital superbugs, researcher said. An estimated 70% of hospital acquired infections in the U.S. involve bacteria that are resistant to at least one antibiotic. Using a process called lysogenization, scientists used bacteriophages, viruses that can infect bacteria, to invade resistant bacterial cells and restore their...

Recently an antibiotic resistant strain of bacteria was found to possess a plasmid containing a unique drug resistance gene. Scientists and physicians are extremely concerned about this discovery since this drug resistance gene is usually only found as a part of the bacterial chromosome (nucleoid). In 1 bullet point --Explain the differences between chromosomal DNA (nucleoid) and plasmids. In 2 bullet points -- Explain why the medical community is so concerned about the the discovery of this particular antibiotic resistant...

A) The widespread misuse of antibiotics, in both humans and livestock, has led to widespread antibiotic resistance among bacterial strains that infect humans and other animals. Antibiotic resistance is a genetic trait, encoded by specific alleles that emerge through mutation. Do antibiotics cause the mutations that lead to resistance? B.) Why is it said that the emergence of mutations is the result of who wins in a race between DNA repair and DNA replication? C.) Certain DNA sequences are especially...

83- There has been a rise of antibiotic resistant bacteria that have arisen due to the improper usage of antiobiotics (e.g. feeding antibiotics to farm animals and people not taking all of their antibiotics as they should). Based on the three types of horizontal gene transfer, which one do you expect is producing antibiotic resistant strains? Explain why they resemble the ancestor that gave rise to all fungi, whereas yeast are members of the most advanced fungi. What type...
