Which set of terms describes the destruction of most pathogenic organisms and their products?

• A. Sterilization
• B. Asepsis
• C. Antisepsis
• D. Disinfection

Answer: (D)

Disinfection refers to the process that eliminates most pathogenic organisms and their products on inanimate surfaces or objects. It significantly reduces microbial contamination, but it does not guarantee total sterility—some hardy organisms, such as spores, may survive. Sterilization would completely destroy all forms of life, including spores. Asepsis describes practices that keep environments free from infection or contaminated by pathogens, while antisepsis involves applying chemical agents to living tissue to inhibit or destroy microorganisms. So, for removing the majority of pathogens from nonliving surfaces, disinfection is the correct concept.
