Coral Yellow Band Disease; current status in the Caribbean, and links to new Indo-Pacific outbreaks

چکیده
Yellow band disease (YBD) has had severe impacts on major reef-building corals throughout the Caribbean. Recent data from Bonaire indicates that this disease remains in an epidemic phase showing similar trends compared to the late 1990s. Ten meter belt transects taken at varied depths of Montastraea spp. indicate high indices of yellow band lesions. At 5m depth, yellow band rings and lesions were positively identified on an average of 9.4 (87%) colonies per transect while an average of 1.2 (13%) colonies in this depth range appeared healthy. At 10m depth an average of 1.0 (12%) healthy colonies and 8.3 (88%) colonies affected by YBD per 10m transect were counted. At 15m there were an average of 0.7 (17%) healthy colonies and 2.6 (83%) colonies affected by YBD per 10m transect. These studies coincide with recent severe outbreaks in the Indo-Pacific where similar lesions were found on Diploastrea spp., Herpolitha spp.and Fungia spp. Inoculation experiments of Indo-Pacific bacterial isolates under ambient temperatures cause the induction of YB lesions onto Montastraea spp. in vitro. YBD continues to be in an infectious stage in its original Caribbean hot spots and appears to be spreading in Pacific coral genera.

متن کاملCyanobacteria associated with coral black band disease in Caribbean and Indo-Pacific Reefs.
For 30 years it has been assumed that a single species of cyanobacteria, Phormidium corallyticum, is the volumetrically dominant component of all cases of black band disease (BBD) in coral. Cyanobacterium-specific 16S rRNA gene primers and terminal restriction fragment length polymorphism analyses were used to determine the phylogenetic diversity of these BBD cyanobacteria on coral reefs in the...

The effectiveness of management plans developed for responding to coral disease outbreaks is limited due to the lack of rapid methods of disease diagnosis. In order to fulfill current management guidelines for responding to coral disease outbreaks, alternative methods that significantly reduce response time must be developed. Hyperspectral sensing has been used by various groups to characterize...
متن کاملAlgae as Reservoirs for Coral Pathogens
Benthic algae are associated with coral death in the form of stress and disease. It's been proposed that they release exudates, which facilitate invasion of potentially pathogenic microbes at the coral-algal interface, resulting in coral disease. However, the original source of these pathogens remains unknown. This study examined the ability of benthic algae to act as reservoirs of coral pathog...

Diseases occur globally in most coral reef habitats whether near human population centers or remotely offshore. They generally affect a low proportion of the susceptible species, although localized outbreaks have produced significant mortalities to scleractinian corals, gorgonians, sea urchins, reef fish, sponges, algae and other coral reef organisms (Peters, 1993; Harvell et al., 1999; William...
