Introduction
The S. aureus enterotoxins (SEs) are potent gastrointestinal exotoxins synthesized by S. aureus throughout the logarithmic phase of growth or during the transition from the exponential to the stationary phase. They are active in high nanogram to low microgram quantities, and are resistant to conditions (heat treatment, low pH) that easily destroy the bacteria that produce them, and to proteolytic enzymes, hence retaining their activity in the digestive tract after ingestion.

Q: During the manufacture of the recombinant Staphylococcus aureus enterotoxin E, were any native toxin genes used at any stage, or were all genes synthetically produced?
A: No native toxin or live S. aureus is used in production. The entE gene is carried on a standard plasmid expression vector and propagated in E. coli.
