Excerpts: ... Study questions for discussion 1: Resistance to antibiotics 1. Why do some argue that non-pathogenic bacteria
living on our skin and mucous membranes actually plays a positive role in reducing disease? (See article in the magazine Scientific American.) Non-
pathogenic bacteria can protect us from harmful bacteria by competing with them, thus reducing their population and reduce strattera the likelihood that they will generate disease. This is one reason that antibiotics are counterproductive when bacteria
pathogens are resistant, killing others, not bacteria, antibiotics will most likely accelerate the accumulation of bacteria
pathogens, worsening the disease. 2. What are the biochemical mechanisms underlying resistance to antibiotics? There are several possible mechanisms. Bacteria can develop. decreased cell permeability to the drug used. more effective antibiotics active pumping of cells in. enzymes that more efficiently absorb antibiotics (R. ..
