Bacterial defenses against oxidative stress.

Author information

Laboratory of Molecular Biology, National Cancer Institute, Bethesda, MD 20892.


Bacteria treated with low doses of oxidants such as hydrogen peroxide adapt to subsequent high doses of these oxidants by inducing the expression of numerous genes. The study of these genes and the roles they play in defending bacteria against oxidative damage has given general insights into what oxidants are hazardous to cells, what cell constituents are damaged by oxidants, and how cells sense and respond to oxidative stress.
