RESUMO
Aims: Different studies have shown that members of the Vibrio such as Vibrio coralliilyticus and Vibrio shiloi are opportunistic pathogens which can cause coral lysis. The aims of this study were to assess whether this results of the virulence of V. coralliilyticus are transmittable to Acropora hyacinthus and Porites lobata, and what role the microbiome of the corals plays during exposure to V. coralliilyticus. Methodology and results: In laboratory-based experiments, we examined the impact of V. coralliilyticus (ATCC BAA- 450) to the microbiome of Acropora hyacinthus and Porites lobata. A. hyacinthus and P. lobata were exposed to ampicillin, V. coralliilyticus, and a combination of both. Results indicate a resistance of A. hyacinthus to V. coralliilyticus through the microbiome and underpin the importance of the microbiome for the coral’s health. Conclusion, significance and impact study: Further studies are needed to identify the bacteria responsible for the coral resistance and could in future lead to the development of a probiotic treatment or prevention of bleaching for sensitive corals.
