I fоund this discussiоn оn аnswerbаg.com. It’s аmazing what one can find on the Internet! 🙂 ----------------------------------------------------------------------------- Q: Why are gram–positive bacteria typically more resistant than gram–negative bacteria to antibiotics that disrupt plasma membranes, such as polymyxin B? A. Gram positive bacteria have a cell wall surrounding the organism, including the plasma membrane. A plasma membrane is usually made up of lipids, which can easily move around to let other molecules in. Meanwhile, a cell wall is a more rigid structure that is not as easily broken. The best way I understand it is by imagining someone wearing a suit of armor. The armor is like the cell wall, which protects the person (or bacteria) from arrows (or the antibiotics). The person with armor is better protected than another person without any armor. Likewise, a bacterium with a cell wall has more protection than one with only a plasma membrane. -------------------------------- Polymyxin B is a cationic surface agent that binds to LPS in the cell, which results in increased permeability and cell death. Gram-positive bacteria are more resistant to polymyxin B than Gram-negative bacteria for all of the following reasons EXCEPT:
