A. enterotoxins
B. antitoxins
C. cytotoxins
D. endotoxins
E. neurotoxins
Homework Answers
The bacteria that cause diphtheria harm the host by producing and releasing A. enterotoxins.
corynebacterium diptheria causes diptheria , a disease of upper respiratory tract,diptheria toxin alters host protein function.This toxin is a exotoxin,thus enterotoxin is the right answer as it is a protein exotoxin released by microorganisms.
Add Answer to:
