Lactococcus garvieae in wild Red Sea wrasse Coris aygula (Labridae)

Lactococcus garvieae infection in wild wrasse Coris aygula is reported, and the serological and molecular characteristics of the isolate are described. This is the first evidence of the presence of this pathogen in the Red Sea, and it follows the recent diagnosis of Mycobacterium marinum and Streptococcus iniae in wild fish from the same region. Whether all 3 pathogens are strains endemic to the Red Sea, or recent introductions into the region, remains to be determined, but their appearance over a period of a few years in wild fish populations in the northern Red Sea is consistent with an emerging trend affecting marine organisms on a global level in areas subjected to intense anthropogenic impacts.
