CHSC 404 - Advanced Pathophysiology: Etiologic Agents

Advanced Pathophysiology

"What is the difference between signs and symptoms?"

Etiologic Agents

Etiologic agents include biologic agents, physical forces, chemical agents, genetic inheritance, nutritional influence (Norris & Tuan, 2020, p. 2).

Explore and get familiar with these related sources.


Biologic Agents

"The agents that cause disease fall into five groups: viruses, bacteria, fungi, protozoa, and helminths (worms). Protozoa and worms are usually grouped together as parasites, and are the subject of the discipline of parasitology, whereas viruses, bacteria, and fungi are the subject of microbiology." Pathogens also include infectious proteins called prions (Alberts et al., 2002; Janeway et al., 2001).
