What term is used for agents that cause diseases, such as bacteria and viruses?

1. Microorganisms

2. Pathogens

3. Antigens

4. Infections

The correct answer is: Pathogens

The correct term for agents that cause diseases, such as bacteria and viruses, is "pathogens." This term specifically refers to any organism or substance that can lead to an infection or disease in a host. Pathogens include a wide variety of disease-causing entities, including not just bacteria and viruses, but also fungi and parasites. Understanding this distinction is crucial for anyone in the field of esthetics and health, as it allows professionals to better comprehend how certain microorganisms can affect skin health and contribute to esthetic concerns. Pathogens can also play a significant role in conditions like acne or skin infections, making it essential for estheticians to be knowledgeable about these agents in order to provide effective care and treatment. The other terms can be contextualized as follows: "microorganisms" is a broader term that includes both harmful (pathogenic) and harmless organisms; "antigens" refer specifically to substances that provoke an immune response, often found in pathogens; and "infections" describe the result of pathogens invading the body, rather than the pathogens themselves. Hence, "pathogens" is the most accurate description for disease-causing agents.
