Over the past decade the accounts of various coral diseases have been on the rise which had lead to the decimation of keystone species of corals throughout mainly the world’s tropical oceans. Since the mid-1990s, 18 coral diseases affecting at least 150 scleractinian, gorgonian, and hydrozoan zooxanthellate species have been described in the Caribbean and Indo-Pacific (Sutherland et al. 2004). Most of these diseases have been caused by bacterial, fungal, and protist type pathogens as well the increased sea temperatures, pollution, and eutrophication. Sutherland et al. says that it is estimated that worldwide 27% of coral reefs have been lost with 16% at serious risk and the corals exhibiting diseases have increased 218% between 1996 and 2000 alone (2004). With the increasing amounts of disease, some of which are genera specific, many areas are left in total devastation and in need of conservation and better understanding of the underlying causes.
White Band Disease (WBD) has been observed in the Red Sea and Philippines, which is the first record for the disease in the Indo-Pacific region where the effects of the disease are most severe among Acroporidae (Antonius 1985). Although it is not infectious it is still causing major declines in the acroporid corals that it infects. Around 2-42% of acroporid colonies have been affected by WBD, which is characterized by a white band of bare calcium carbonate skeleton which often shows the presence of bacterial aggregates (Peter et al.…
