When the same kind of analysis was performed for emm types and individual SAg genes, three combinations with statistical significance emerged: the association of isolates presenting emm1 and speA, and emm1 and speJ with invasive infections (P < 0.001), and the association of isolates carrying emm75 and speL/M with pharyngitis (P = 0.001). Here, PIGG is linked to pharyngitis.
