Question

which of the following statements from your lecture is true regarding why these organisms may be used in bioterror attacks?
○ salmonella has a toxin that is effective in low dose
○ shigella toxin is effective in low doses
○ staphylococcus aureus has a low infectious dose
○ staphylococcus aureus toxin is effective in low doses

Explanation:

Shigella toxin, specifically Shiga toxin, is highly potent. Even in low doses, it can cause severe damage to the human body, such as affecting the intestines and kidneys. This high potency makes it a candidate for bioterrorism as a small amount can lead to significant harm. Staphylococcus aureus has a relatively higher infectious dose requirement compared to some other highly virulent agents for causing major harm. Salmonella's toxin is not as extremely potent in low doses as Shigella's in the context of being a prime bioterror threat in terms of toxin - related impact with minimal quantity.

Answer:

Shigella toxin is effective in low doses
