This article reviews the literature regarding the structure and function of two types of exotoxins expressed by Staphylococcus aureus, pyrogenic toxin superantigens (PTSAgs) and hemolysins. The molecular basis of PTSAg toxicity is presented in the context of two diseases known to be caused by these exotoxins: toxic shock syndrome and staphylococcal food poisoning. The family of staphylococcal P...

Staphylococcal foodborne illness, caused by the ingestion of contaminated foods induced Staphylococcus aureus enterotoxins, is one most recurrent diseases worldwide. Food handlers working in food-service establishments who carry enterotoxigenic isolates represent a reservoir for potential contamination leading to staphylococcal food intoxication. The aim this research was investigate prevalence...

BACKGROUND Accurate and rapid diagnosis of bacterial arthritis is not always possible in unvaccinated (Streptococcus pneumoniae and Haemophilus influenzae type B) children in Iran. OBJECTIVES Searching the staphylococcal superantigen (entrotoxin A, B, C and TSST1) in synovial fluid of cases with inflammatory arthritis. PATIENTS AND METHODS This cross sectional study was implemented in the p...

Two cases of scarlet fever are described, both following super-infection of chickenpox. Enterotoxin B and C producing staphylococci were the only pathogens identified. The role of staphylococcal and streptococcal toxins in the pathogenesis of scarlet fever and toxic shock syndrome is discussed.

conclusions based on the findings of this study, s. aureus enterotoxin c (sec) has been detected in synovial fluid of patients with rheumatoid arthritis by pcr and elisa methods. these valuable findings may describe the exact etiology of the ra and as well as change the methods of its diagnosis and treatment. this is the first research, which has shown the staphylococcal entc gene in synovial f...
