    Select and describe one example of antibiotic OR pesticide resistance. How about Penicillin? Is this a resistance antibiotic? Describe the background for the choice of resistance. Include details about the disease or pest and the established control strategies. How have we used antibiotics( to treat a particular disease), or pesticides (to protect from a pest), and how has this changed.
    Explain how the resistant trait evolved based on principles of natural selection and evolution of a trait at the population level.
    For the example being used , what are the consequences of resistance in terms of human health or crop loss/damage.
    What steps can be taken to prevent or slow down the evolution of antibiotic OR pesticide resistance? Do you think we will succeed in doing so? Why OR why not?

    one example of antibiotic resistance is the evolution of "super bugs" such as drug resistant TB. TB is caused by Mycobacterium tuberculosis bacteria. This disease usually attacks the lungs but it can occur elsewhere in the body. If not treated, it can be fatal. TB is an airborne disease, one can catch it much the same way that you can catch a cold; through a cough or a sneeze, when the person speaks or sings.Drug resistant TB is a TB infection which is resistant to penicillin and other front line antibiotics.
    In the past, before antibiotics, people with TB usually went to dry climates and let the disease run its ...

    Solution Summary

    this solution discusses how antibiotic resistance is developed by natural selection among a population of Mycobacterium tuberculosis and its affects on the human population.
