Dominant bacterial phylogenetic groups, based on 16S rRNA gene sequence types and universal primers, present in clone libraries produced from frozen and unfrozen BBD samples from the coral hosts Siderastrea siderea and Diploria clivosa. The numbers above the bars represent the numbers of sequences in the respective clone libraries. Libraries A to H, frozen (A to G) and unfrozen (H) BBD from S. siderea. Libraries I and J, frozen (I) and unfrozen (J) BBD from D. clivosa. Sampling locations and sampling dates: libraries A and B, Horseshoe Reef, Lee Stocking Island, Bahamas, 19 July 2004; C, Rainbow Garden Reef, Lee Stocking Island, Bahamas, 16 July 2004; D, Watson's Reef, Florida Keys, 3 May 2005; E, G, and H, Butler Bay Reef site, St. Croix, U.S. Virgin Islands (USVI), 22 October 2005, 1 June 2005, and 5 June 2006, respectively; F, Frederiksted Reef site, St. Croix, USVI, 1 June 2005; I and J, Frederiksted Reef site, St. Croix, USVI, 7 August 2006. All of the sequences from clone libraries A to G have been previously published by Sekar et al. (19, 20).
