The production of TSST-1, SEB, and SEC in liquid culture has been quantified previously in S. aureus isolates from atopic dermatitis, vaginal mucosa, and diabetic foot ulcers, where strains produced 3 to 39 μg/ml TSST-1, 25 to 120 μg/ml SEB, and 10 to 120 μg/ml SEC (28). This evidence concerns the gene SETBP1 and diabetic foot.
