RESUMO

The presence of antibodies to staphylococcal enterotoxins (enterotoxins A through F) in sera of healthy subjects (n = 567) and in sera of patients with toxic shock syndrome (n = 20) was determined. Furthermore, production of enterotoxins by Staphylococcus aureus isolated from humans was investigated. In 46, 86, 78, 41, 20, and 91% of the sera of healthy subjects, antibodies were found against enterotoxins A, B, C, D, E, and F, respectively. The high percentage of sera with antibodies against enterotoxin F correlated with the relatively high frequency of enterotoxin F-producing S. aureus isolated from humans (one-third of the isolates produced enterotoxin F). In patients with toxic shock syndrome, antibodies against enterotoxin F were not present or were present only at very low levels. An increase of antibodies after onset of the disease was observed in two of eight patients investigated. From the results, it can be concluded that only those humans who show low levels of antibodies are susceptible to toxic shock syndrome.
