Bacteria Good for Your Skin?

Wednesday December 9, 2009

In a recent study scientists have been able to identify the mechanism that the bacteria, Staphylococcus aureus, uses to reduce inflammation on the skin.

The conventional thinking on wound healing has been that chemicals causing inflammation in a wound are necessary for wound healing. Lately, studies have been showing that good wound healing occurs when there are low levels of these inflammatory chemicals.

The skin always has bacteria on it, the same bacteria that cause infections if they get into the body. This study showed that one of those skin bacteria, Staphylococcus aureus, produces a molecule that blocks a certain receptor on the skin from making inflammatory chemicals in response to a wound.

But it doesn't block all of the inflammation. This bacteria is able to keep the receptor from making too many inflammatory chemicals. It allows just enough required for good wound healing.
