Quizplus · Accepted Answer

A disease-causing agent is also known as a pathogen. It can be a virus, bacterium, fungus, parasite, or any other microorganism that can cause illness or disease in a host. In contrast, a macrophage is a type of white blood cell that helps to defend against pathogens by engulfing and destroying them. Antibodies and antitoxins are specific proteins produced by the body's immune system in response to the presence of a pathogen or toxin, respectively.
