Prevalence of IgG Anti-Staphylococcus aureus Enterotoxin (Superantigen) in the 3 Study Cohorts
| Cohort | Number | IgG anti-SEA >32.2 mgA/L | IgG anti-SEB >53.5 mgA/L | IgG anti-TSST 70.5 mgA/L | IgG anti-SEA, SEB or TSST positive |
|---|---|---|---|---|---|
| Cohort A | 49 | 13 (26.5%) | 5 (10.2%) | 7 (14.3%) | 18 (36.7%) |
| Cohort B | 48 | 7 (14.6%) | 4 (8.2%) | 4 (8.2%) | 9 (18.8%) |
| Cohort C | 46 | 3 (6.5%) | 5 (10.8%) | 5 (10.8%) | 7 (15.2%) |
The 95% CI limits for age-adjusted IgG anti-Staphylococcus aureus superantigen reference ranges for healthy female adults derived from Cohort C are 32.3 mgA/L (SEA), 53.6 mgA/L (SEB) and 70.5 mgA/L (TSST). Ig, immunoglobulin; SEA(B), Staphylococcus aureus enterotoxin A(B); mgA/L, milligrams of antigen-specific antibody per liter; TSST, toxic shock syndrome toxin.
