“…Colonies affected by both PUWS and tumors were occasionally observed. Pigmentation response is an ill-defined condition, commonly seen in massive Porites and possibly associated with the cyanobacterium Phormidium valderianum (referred to as pink line syndrome by Ravindran & Raghukumar 2002). It is characterized by irregular patches of dead skeleton on massive Porites, bordered by a highly pigmented margin.…”

“…Preliminary work on a new disease, PUWS, quantified its host range, prevalence, incidence and seasonality in the central Philippines . Pink line syndrome (here referred to as pigmentation response) is widespread throughout the Indo-Pacific and thought to be caused by the cyanobacterium Phormidium valderianum (Ravindran & Raghukumar 2002), but the pathogen has not yet been isolated from diseased tissues, nor has it satisfied Koch's postulates. A transfection study carried out in laboratory aquaria suggested that the condition is not infectious (Azcuna 2005).…”

“…As with other coral diseases, the zone of dead skeleton is bright white in appearance, indicating a relatively rapid rate of disease progression (Ravindran et al 2001). PLS is associated with the cyanobacterium Phormidium valderianum, which induces pink coloration of coral tissue, hypothesized by increasing levels of pCO 2 (Ravindran & Raghukumar 2002).…”

Since the mid-1990s, coral diseases have increased in number, species affected, and geographic extent. To date, 18 coral diseases, affecting at least 150 scleractinian, gorgonian, and hydrozoan zooxanthellate species, have been described from the Caribbean and the Indo-Pacific. These diseases are associated with pathogens including bacteria, cyanobacteria, fungi, and protists and with abiotic stressors including elevated seawater temperature, sedimentation, eutrophication, and pollution. Etiologies of only 5 of the 18 coral diseases have been determined through fulfillment of Koch's postulates. Corals and other invertebrates utilize innate immune mechanisms including physiochemical barriers and cellular and humoral defenses against pathogens. Here we review the described coral diseases, known etiologies, and efforts to determine unknown etiologies. We define disease terms, discuss the limitations of Koch's postulates, describe alternative techniques for identifying disease-causing organisms, and review coral immunology.

“…However, the impacts of coral disease on Indian Ocean reef communities are largely unknown. Although coral diseases have been studied in the adjoining Red Sea (Antonius 1985) and Arabian Gulf (Riegl 2002), there have only been preliminary reports of disease in the Indian Ocean (Coles 1994, Coles & Seapy 1998, Antonius & Afonso-Carillo 2001, Ben-Haim & Rosenberg 2002, Ravindran & Raghukumar 2002 and little is known of the prevalence, distribution and impact of these and other unreported diseases on Indian Ocean coral reefs (McClanahan et al 2004).…”

Coral diseases, such as white diseases and white syndrome (WS), have caused widespread damage to coral reefs throughout the Caribbean and are increasing in prevalence on Pacific Ocean reefs. The current study confirms that WS is also present on coral reefs in the Indian Ocean and tests whether patterns in taxonomic susceptibility and spatial variability conform to patterns of WS reported in the Pacific Ocean. Underwater surveys at 19 sites around Christmas and Cocos Islands revealed that WS primarily affects Acropora plate corals (A. clathrata, A. cytherea and A. hyacinthus), and prevalence of WS varied significantly across all 3 spatial scales investigated (island, exposure and depth). Approximately 13.0% (range = 0 to 43% per site) of plate corals at Christmas Island sites exhibited WS compared to <1% at the Cocos Islands. At Christmas Island, WS prevalence was greater in shallow (31.5%) than in deeper water (6.7%) and greatest on the northern (leeward) side of the island (31.5%) compared to the more exposed coastlines (0 to 1.5%). Importantly, the spatial distribution of WS was positively correlated with host density, but not with hard coral cover, suggesting a role of host density in WS outbreaks. Overall the present study has established that WS is impacting remote, near-pristine reefs in the Indian Ocean. However, the highly variable spatial distribution of WS illustrates that patterns in disease prevalence, and the subsequent impact on coral reefs, can be location-or region-specific.
