Maximum likelihood phylogenetic analysis based on eight gene loci. Boldface type indicates study isolates. Brackets indicate Vibrio clades containing isolates from A. palmata colonies. Bootstrap values (≥70) for 500 iterations are shown. Abbreviations for isolation source: H, mucus from apparently healthy A. palmata colonies with no WPX signs; DPX, mucus from WPX lesions; DH, mucus from asymptomatic areas on colonies with WPX lesions; reef H2O, seawater from approximately 1 m above the A. palmata colonies; surface H2O, seawater from the first 10 cm of the sea surface.
