Temperature-regulated bleaching and lysis of the coral Pocillopora damicornis by the novel pathogen Vibrio coralliilyticus

Article Abstract:

Research points out that coral bleaching is caused by bacteria and that Vibrio coralliilyticus is the etiologic agent of bleaching of Pocillopora damicornis found on coral reefs. Furthermore, seawater temperature plays a critical environmental role in influencing the outcome of infection as indicated by an increase in the extracellular protease activity of V. coralliilyticus occurring at the same temperature as the transition from bleaching to lysis of the corals.

Purification and characterization of a vulnificolysin-like cytolysin produced by Vibrio tubiashii

Article Abstract:

A cytolysin isolated from Vibrio tubiashii that has sequence homology to the cytolysin of Vibrio vulnificus is described. Vibrio tubiashii infects mollusks in the US and UK and has been linked to red tides along the Spanish coast.

Proline-rich peptide from the coral pathogen Vibrio shiloi that inhibits photosynthesis of zooxanthellae

Article Abstract:

Toxin P from Vibrio shiloi appears to bleach coral by facilitating the transport of ammonia into the coral symbiotic algae. This destroys the pH gradient and inhibits photosynthesis.
