Vibrio zinc-metalloprotease causes photoinactivation of coral endosymbionts and coral tissue lesions.

<h4>Background</h4>Coral diseases are emerging as a serious threat to coral reefs worldwide. Of nine coral infectious diseases, whose pathogens have been characterized, six are caused by agents from the family Vibrionacae, raising questions as to their origin and role in coral disease ae...
