  • a Titer of serum antibody against TSST-1.

  • b Low hemoglobin density refers to tampon sections that appear white, whereas high hemoglobin density refers to sections that appear red.

  • c ND, none detected.

  • d The total amounts of TSST-1 were considered significantly different (P < 0.002) by the Student t test.
