Which term is used for disease-producing microorganisms?

• A. Pathogens
• B. Antibodies
• C. Toxins
• D. Vaccines

Answer: (A)

Disease-causing microorganisms are called pathogens. This term covers bacteria, viruses, fungi, and parasites that can invade the body and cause illness by damaging cells, releasing harmful substances, or triggering an immune response. Antibodies are immune system proteins that fight infection, not organisms. Toxins are poisonous substances some pathogens produce, contributing to illness but they’re not microorganisms themselves. Vaccines are preparations that help the immune system recognize and fight pathogens, not the organisms. Remember, many microorganisms are harmless or even beneficial, but pathogens specifically lead to disease.
