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.

Fractions of Staphylococcal Enterotoxin B

Nature, 1965
IN a recent paper1 we showed that enterotoxin B isolated from Staphylococcus aureus strain S6 could be separated into two main protein fractions by starch-gel electrophoresis. After the completion of this work we received communications concerning this observation from Dr. M. S. Bergdoll (University of Chicago) and from Dr. E. J. Schantz (U.S.

Heterogeneity of staphylococcal enterotoxin B

Canadian Journal of Microbiology, 1971
Different forms of enterotoxin B obtained by hydroxyl apatite column chromatography and isoelectric focusing were found to produce lines of apparent serologic identity, but to differ in toxicity. This is interpreted to mean that the antigenic site or sites and toxic site or sites are most probably not the same in the molecule of enterotoxin B.

Purification of staphylococcal enterotoxin E

Natural Toxins, 1993
AbstractStaphylococcal enterotoxin E has been purified by a combination of Red‐A ligand chromatography and Mono‐S (cation – exchange) chromatography. Commencing with 30 litres of fermenter‐grown culture the method has been used to purify 17 mg of toxin, giving a purification yield of around 40%.

Staphylococcal enterotoxin. I. Purification

Archives of Biochemistry and Biophysics, 1959
Abstract A procedure for purifying enterotoxin from the Staphylococcus strain S-6 has been outlined. Acid precipitation, adsorption on alumina, precipitation by ethanol, chromatography on IRC-50, and zone electrophoresis on starch were the methods used.

The 3D Structure of Staphylococcal Enterotoxins

1994
Abstract : The purpose of this research is to determine the crystal structure of the staphylococcal enterotoxins (SEs) by x-ray diffraction and protein modeling techniques and to correlate the 3D structures with their biological activities, in order to provide essential data for use in vaccine, or other effective counteractant, development.
