Which species of shigella has a type that produces shiga toxin?
s. boydii
s. flexneri
s. dysenteriae

S. dysenteriae.

Explanation:

Shiga toxin is expressed by the genes that are the part of the lamboid prophage genome. The main symptoms of shiga toxin are water diarrhea and abdominal pain.

Shiga toxin is produced by the species S. dysenteriae. Shigella is a gram negative bacteria and has the ability to replicate at the epithelial cells of the host organism.

Thus, the correct answer is option (3).

yes, because even though a theory has a  lot of evidence to support it, it is not always true

fumikage isn't really a bird, and tsuyu does have teeth. tsuyu has a transformation quirk which still allows her to be partially human. otherwise we'd have a large frog running around. fumikage has teeth because again, he isn't a bird. his head was a quirk mixture if i'm correct.
