Staphylococcal enterotoxins

International Journal of Food Microbiology, 2000
Staphylococcus aureus is a major human pathogen that produces a wide array of toxins, thus causing various types of disease symptoms. Staphylococcal enterotoxins (SEs), a family of nine major serological types of heat stable enterotoxins, are a leading cause of gastroenteritis resulting from consumption of contaminated food.

The Staphylococcal Enterotoxins and Their Relatives

Science, 1990
Staphylococcal enterotoxins and a group of related proteins made by Streptococci cause food poisoning and shock in man and animals. These proteins share an ability to bind to human and mouse major histocompatibility complex proteins.

Staphylococcal Enterotoxin

The Journal of Immunology, 1959
Summary A specific precipitate band obtained by the gel diffusion technique has been identified as the enterotoxin-antienterotoxin band. A monovalent serum specific for enterotoxin produced by staphylococcus strain S-6 was prepared. Highly potent enterotoxin from thirteen food poisoning stains of Staphylococcus cross reacted with this ...

Staphylococcal enterotoxin. II. Chemistry

Archives of Biochemistry and Biophysics, 1959
Abstract A study of some chemical and physical properties of purified staphylococcal enterotoxin has been reported. The enterotoxin has a molecular weight of 24,000 ± 3000 and an isoelectric point at pH 8.6. There is no indication of the presence of carbohydrate and lipide. The amino acid content has been determined.

Staphylococcal Enterotoxin A Is Encoded by Phage

Science, 1985
The gene for staphylococcal enterotoxin A ( entA ), in two wild-type strains, is carried by related temperate bacteriophages. Hybridization analysis of DNA from entA -converting phage PS42-D and its bacterial host suggests that this phage integrates into the bacterial chromosome by ...

Staphylococcal Enterotoxin: Effect on Protozoa*

The Journal of Protozoology, 1965
SYNOPSIS. Various protozoa and lower metazoa were exposed to filtrates of Staphylococcus aureus B (formerly called Type S‐6) (2) and non‐enterotoxigenic filtrates of staphylococci to study the toxicity of staphylococcal enterotoxin to these organisms.

Regulation of Staphylococcal Enterotoxin B

Journal of Bacteriology, 1969
Several factors influenced the formation of enterotoxin B by Staphylococcus aureus strain S-6. In the standard casein hydrolysate medium, toxin was not produced in detectable quantities during exponential growth; it was produced during the post-exponential phase when total protein synthesis was arithmetic.

Partial purification of staphylococcal enterotoxin

Archives of Biochemistry and Biophysics, 1951
Abstract 1. 1. Enterotoxin was concentrated and partially purified by concentration in vacuo , dialysis, and precipitation with (NH 4 ) 2 SO 4 , acid, ethanol, and methanol. 2. 2. The stability of enterotoxin under various conditions was determined. 3. 3. It is tentatively concluded that enterotoxin is a protein.
