Summary
Most Staphylococcus aureus isolates causing toxic shock syndrome (TSS) produce TSST-1. Patients with TSS showed reduced antibody levels to TSST-1 and other staphylococcal enterotoxins, suggesting potential immunodeficiency.
Area of Science:
- Microbiology
- Immunology
- Toxicology
Background:
- Toxic Shock Syndrome (TSS) is a severe illness primarily associated with Staphylococcus aureus infections.
- Staphylococcal toxins, including Toxic Shock Syndrome Toxin-1 (TSST-1) and staphylococcal enterotoxins, are key virulence factors in TSS pathogenesis.
Purpose of the Study:
- To investigate the prevalence of TSST-1 and other staphylococcal enterotoxins in Staphylococcus aureus isolates from TSS patients.
- To assess antibody levels against TSST-1 and staphylococcal enterotoxins in individuals with TSS compared to healthy controls.
Main Methods:
- Bacterial cultures from 434 individuals with confirmed or probable TSS were analyzed for toxin production.
- Serological testing was performed on sera from 284 TSS patients and 103 healthy controls to quantify antibodies against TSST-1 and staphylococcal enterotoxins A, B, and C.
Main Results:
- 91.6% of Staphylococcus aureus isolates produced TSST-1, often in combination with other enterotoxins.
- Isolates co-producing staphylococcal enterotoxin C and TSST-1 were more frequently associated with nonmenstrual and fatal TSS cases.
- TSS patients exhibited significantly lower detectable antibody levels to TSST-1 (82.4%) and other staphylococcal enterotoxins compared to healthy controls.
Conclusions:
- TSST-1 is a predominant toxin produced by Staphylococcus aureus in TSS cases.
- The reduced antibody response in TSS patients suggests a possible underlying immunodeficiency affecting antibody production or maintenance against staphylococcal toxins.
