When antibiotics were first introduced, there was virtually no human pathogen that had resistance. But resistance did exist in other nonpathogenic bacteria. Why may these other bacteria have possessed resistance?
Homework Answers
Answer: Some of the bacteria becomes resistant towards the antibiotics as because antibiotics are being targeted to the specific form of bacteria but some of the bacteria are capable to transform.
Transformation of bacteria prevents them from the action of the antibiotics and which causes them replicates and forms more resistant towards the antibiotics treatment. Some of bacteria escapes from the antibiotics action.

Evolutionary theory predicts that bacterial resistance to antibiotics will evolve. Given time and sufficient heritable variability, living organisms (including bacteria) will evolve when a selective pressure (like an antibiotic) is introduced. But evolutionary theory also gives doctors and patients some specific strategies for delaying even more widespread evolution of antibiotic resistance. For the following strategies, give a justification based on your knowledge of bacteria and evolution, why this strategy would reduce or slow the transmission of antibiotic resistance. a. Don't...

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...

3. Do you agree or disagree with the following statement? Explain. "Mutations conferring antibiotic resistance occur in order to protect bacteria from antibiotics." 4. How does mutation rate differ from mutation frequency? Does either affect the other? 5. Why were streptomycin-resistant mutants not detected in many or most of the cultures? 6. When streptomycin-resistant mutants were detected, why did their numbers differ, perhaps very widely, among cultures?

Case study: TB Bacteria are capable of developing resistance to antibiotics because they can divide rapidly. Physicians may prescribe a combination of more than one antibiotic to combat antibiotic resistance. For example, patients diagnosed with active tuberculosis are given a combination of isoniazid, rifampin, pyrazinamide, and either ethambutol or streptomycin for 6 months However, antibiotic resistant strains still emerge for the following reasons: when patients do not complete their full course of treatment; when health-care providers prescribe the wrong treatment,...

When the Universal Declaration of Human Rights was adopted in 1948, human rights were considered essentially the responsibility of national governments. By the 1970s, however, Non-Governmental Organizations (NGOs) played a large role in the pursuit of human rights. 1) Why might his have been the case? 2) What forms did human rights activism take?

Bacteria and Drug Resistance If you don't take all your antibiotics when you are sick, you could be creating super drug resistant bacteria. Create a Bacteria class and run some simulations of results. Classes You will have to implement a couple of classes in this creating the classes with methods as given will help quite a bit when it comes to finishing up this program. The methods given here have to be implemented as given, however, you...
