Streptococcus phocae

◔ Human-origin
Sequenced
Public genome assembly available

Streptococcus phocae is a Gram-positive coccus originally identified in marine mammals and now recognized as an emerging pathogen in fish aquaculture and other vertebrate hosts. The pathogen has been recovered from diseased salmon, sea otters, seals, and mink, with strain heterogeneity in surface properties and pathogenic potential documented by genomic analysis and host-specificity studies. Research has examined its infectivity in cell culture systems and characterized epidemiological risk factors associated with infection. This is not an established probiotic organism.
