What is one feature of Staphylococcal Enterotoxin B that makes it a serious biological threat agent?

• A. It can be aerosolized and purified and put into water or food
• B. It can only affect animals
• C. It is harmless when inhaled
• D. It is not easily disseminated

Answer: (A)

Staphylococcal enterotoxin B is a potent toxin produced by Staphylococcus aureus that is unusually stable and can be purified into a concentrated form. This makes it able to be disseminated without needing to spread live bacteria. It can be released as an aerosol or contaminate water and food, causing illness in exposed people even at low doses. This combination of potency, environmental stability, and multiple routes of dissemination is what makes it a serious threat. The other statements aren’t accurate because SEB can affect humans, not just animals; it is not harmless when inhaled; and it can be disseminated widely through aerosols and contaminated supplies.
