Evolution and Antibiotic Resistance: TB GSI

Evolution and Antibiotic Resistance What is Antibiotic Resistance? Antibiotic: drug that kills bacteria When resistant, bacteria no longer respond to drug What is natural selection?

Evolution and Antibiotic Resistance Watch “Why Does Evolution Matter Now?” video at: Answer the following questions about the video segment: Why is the Russian prison system considered to be "ground zero" in the fight against TB? What is responsible for the evolution of TB strains that are resistant to multiple drugs? How does the misuse of antibiotics affect the evolution of disease-causing bacteria? Use the theory of natural selection to explain the growing resistance to antibiotics. Why should we care about a resistant strain of TB in Russia?
