An article published October 7, 2014, by USGS microbiologists Christina Kellogg and Michael Gray, examines one of the most prevalent coral diseases in the Caribbean, dark spot disease (also known as dark spot syndrome). In collaboration with scientists from Lawrence Berkeley National Laboratories, DNA microarrays, a technology that measures a large numbers of genes simultaneously, were used to compare bacterial communities between healthy and dark-spot coral colonies in Dry Tortugas National Park and Virgin Islands National Park. Overall, the findings do not support the hypothesis that dark spot in the massive starlet coral (Siderastrea siderea) is linked to a bacterial pathogen. The dataset does provide the most comprehensive overview to date of the bacterial community associated with this coral species.
