Figure 2. Representative denaturing gradient gel electrophoresis (DGGE) gels of bacterial community profiles in healthy corals and water.

DGGE gels of the 16S rDNA hypervariable region V3 show the various bacterial communities present colonies of (A) Stylophora pistillata and (B) Acropora hyacinthus. Water samples and representative profiles of all profile types from all sites (Wistari Reef, Tenements, Harry's Bommie) are included on both gels. Sample numbers are shown above each lane and band numbers indicate the position of bands excised for sequence analyses. *, #, ^∧, § identify samples specifically included because they show significant deviations from the most commonly observed bacterial communities as seen in the majority of samples.
