These isolates were also found to contain several superantigen genes (sea, seb, sec, sed, see, seg, seh, sei, sej, tst) that have been reported to be responsible for the production of pro-inflammatory cytokines, infective endocarditis, scarlet fever, and possibly septic shock syndrome [45,46,47]. This evidence concerns the gene SETBP1 and infective endocarditis.
