||P.357 right column bottom paragraph: "With the exception of the interactions between V. shiloi and O. patagonica, and Vibrio coralliilyticus and P. damicornis [refs 45, 46], there has been only limited microbiological analysis of bleached corals. In one study, Ritchie et al. [primary source] compared culturable heterotrophic bacteria from healthy and bleached Montastraea annularis in the Bahamas. Pseudomonas spp., which represented 13% of the total bacterial isolates obtained from disease-free corals, could not be isolated from bleached corals. By contrast, 30% of all bacteria isolated from bleached corals were Vibrio spp., a genus that was not present in healthy corals. Although the authors of this study suggested that a Vibrio spp. could have been responsible for bleaching, the observed replacement of the Pseudomonas spp. population with Vibrio spp. in the diseased coral could be either the cause or the result of the disease. To distinguish between these two possibilities, infection experiments need to be carried out under controlled conditions."
