Bacteria make us feel pain? and suppress our immune response (8/31/2013)

Boston Children's Hospital researchers found pain from invasive skin infections from Staph, and possibly other serious, painful infections, appear to be induced by the invading bacteria themselves, and not by the body's immune response as previously thought. The research demonstrates that once the pain neurons "sense" the bacteria, they suppress the immune system, potentially helping the bacteria become more virulent. ...> Full Article
