Healthy Elkhorn Coral (IMAGE) University of Georgia Caption Disease-free coral colonies are rare during a white pox disease outbreak, but some colonies (such as those shown here from Molasses Reef) may have natural resistance to this bacterium and may live to recolonize the reef. This cycle of infection and recovery places a premium on maintaining good water quality on the reef so that surviving colonies can regrow quickly. Credit James W.
