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 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 ...
متن کاملExpression of Staphylococcal Enterotoxins under Stress Encountered during Food Production and Preservation
Staphylococcal food poisoning (SFP) is the most prevalent cause of food-borne intoxications worldwide. Consumption of enterotoxins preformed in food causes violent vomiting and can be fatal in children and the elderly. While being repressed by competing bacteria in most matrices, Staphylococcus aureus benefits from crucial competitive advantages in foods with high osmolarity or low pH. During r...
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 کاملInnovative application of mass spectrometry for the characterization of staphylococcal enterotoxins involved in food poisoning outbreaks.
Staphylococcal poisoning is a common food-borne disease for which immunoassays to detect enterotoxins were developed, but these assays often lead to false diagnoses due to interferences or lack of specificity. Absolute quantitative mass spectrometry was for the first time successfully applied to an investigation of a staphylococcal outbreak due to coconut pearls.
