Decreased Cfa activity in the codY mutant. S. aureus strain RN6390 was inoculated vertically on a blood-agar plate and wild and codY mutant strains of S. pyogenes were inoculated horizontally. Cfa activity is indicated by a wedge-shaped increase in hemolysis activity at the intersection of the two bacterial species.
