Enzyme-linked immunosorbent assay for detection of staphylococcal enterotoxins in foods.
An enzyme-linked immunosorbent assay (ELISA) was developed for detection of staphylococcal enterotoxins in foods. The "double-antibody sandwich" protocol combines parts of several procedures reported previously. Horseradish peroxidase was conjugated to antibody specific for an enterotoxin, and the antibody-enzyme conjugate was assayed with a 2,2'-azino-di-(3-ethylbenzthiazoline sulfonic acid)-H...
متن کاملStaphylococcal 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 کاملEvaluation of a commercial enzyme immunoassay kit (RIDASCREEN) for detection of staphylococcal enterotoxins A, B, C, D, and E in foods.
The RIDASCREEN SET kit (R-Biopharm GmbH, Darmstadt, Germany), a commercial staphylococcal enterotoxin (SE) visual immunoassay kit, was evaluated for its efficacy. The kit utilizes monovalent capture antibodies against SE types A to E (SEA to SEE); therefore, it simultaneously detects and identifies the enterotoxin types. The major advantages of the kit are (i) a high degree of specificity (exce...
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 ...
