2. State how the following toxins cause harm and name a bacterium producing each:

a. leukotoxins such as leukocydin
b. Bordetella tracheal cytotoxin

3. State how Toxin A and Toxin B of Clostridioides difficile (formerly known as Clostridium difficile) lead to diarrhea and damage to the colon.

Highlighted Bacterium

1. Read the description of Clostridioides difficile (formerly known as Clostridium difficile) and match the bacterium with the description of the organism and the infection it causes.
