Comparison of bacterial community structure in healthy and diseased coral microbiomes. Bacterial community similarity based on Morisita–Horn β-diversity of Illumina MiSeq 16S rRNA gene libraries in the surface microbiomes of corals with and without BBD, in comparison with overlying seawater, with health state indicated by color and collection location (a) or coral host (b) indicated by symbol shape. Black Band communities sampled in February were consistently different from summer Black Band communities. Healthy surface microbiomes clustered together regardless of collection location or coral species.
