Many methods in use today for the isolation, purification, and
identification of the staphylococcal enterotoxins involve lengthy
steps with significant loss of enterotoxin, are subject to interference
from contaminating sample components, and lack sufficient specificity.
Culture extracts of enterotoxin producing Staphylococcus
aureus strains (enterotoxins A-E), crude enterotoxin preparations
(enterotoxins A-E),...
