Staphylococcal Enterotoxins
Staphylococcus aureus (S. aureus) is a Gram positive bacterium that is carried by about one third of the general population and is responsible for common and serious diseases. These diseases include food poisoning and toxic shock syndrome, which are caused by exotoxins produced by S. aureus. Of the more than 20 Staphylococcal enterotoxins, SEA and SEB are the best characterized and are also reg...
متن کاملStaphylococcal enterotoxins in scarlet fever complicating chickenpox.
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.
متن کاملThe Systemic and Pulmonary Immune Response to Staphylococcal Enterotoxins
In response to environmental cues the human pathogen Staphylococcus aureus synthesizes and releases proteinaceous enterotoxins. These enterotoxins are natural etiologic entities of severe food poisoning, toxic shock syndrome, and acute diseases. Staphylococcal enterotoxins are currently listed as Category B Bioterrorism Agents by the Center for Disease Control and Prevention. They are associate...
متن کاملTwo common structural motifs for TCR recognition by staphylococcal enterotoxins
Superantigens are toxins produced by Staphylococcus aureus, called staphylococcal enterotoxins (abbreviated SEA to SEU). They can cross-link the T cell receptor (TCR) and major histocompatibility complex class II, triggering a massive T cell activation and hence disease. Due to high stability and toxicity, superantigens are potential agents of bioterrorism. Hence, antagonists may not only be us...
متن کاملStaphylococcal enterotoxins A and B: solid-phase radioimmunoassay in food.
An immunoassay employing (125)I labeled enterotoxins A and B and polystyrene tubes coated with specific antibodies was used for detection and quantitation of enterotoxin in food. Ham salad, cheddar cheese, custard, condensed milk, and salami were studied. Enterotoxin was successfully determined in all the foods by simple extraction procedures. The assay was sensitive to 1 to 10 ng of toxin per ...
