Black Band Disease

Black band disease is characterized by complete coral tissue degradation due to a pathogenic microbial consortium that appears as a dark red or black migrating microbial mat.[1] The mat is present between apparently healthy coral tissue and freshly exposed coral skeleton.The black band microbial consortium consists of an assortment of photosynthetic and non-photosynthetic bacteria that co-exist synergistically.
