A)High invasiveness, high toxigenicity, endotoxin
B)Low invasiveness, high toxigenicity, endotoxin
C)High invasiveness, low toxigenicity, exotoxin
D)Low invasiveness, low toxigenicity, exotoxin
E)Low invasiveness, high toxigenicity, exotoxin

Quizplus · Accepted Answer

Clostridium botulinum is known for producing a highly potent toxin (high toxigenicity) but does not aggressively invade tissues (low invasiveness). The toxin it produces is an exotoxin, which is secreted into the surrounding environment.
