Frogs With Disease-resistance Genes May Escape Extinction

As frog populations die off around the world, researchers have identified certain genes that can help the amphibians develop resistance to harmful bacteria and disease. The discovery may provide new strategies to protect frog populations in the wild. New work examines how genes encoding the major histocompatibility complex affect the ability of frogs to resist infection by a bacterium that is associated with frog population declines.
