Which term describes techniques that eliminate all microorganisms and spores?

• A. Medical Asepsis
• B. Surgical Asepsis
• C. Sterilization
• D. Disinfection

Answer: (B)

Sterilization describes techniques that destroy all forms of life, including spores. This level of decontamination is required for items that will contact sterile body sites and in settings like operating rooms. Methods such as autoclaving (steam under pressure), dry heat, chemical sterilants, and irradiation are used to achieve this complete elimination of viable organisms and spores.

Medical asepsis uses clean technique to reduce or limit the spread of microorganisms but does not guarantee that all microorganisms or spores are gone. Disinfection lowers the microbial load on inanimate surfaces but typically does not kill spores. Surgical asepsis involves maintaining a sterile field and using sterile items during procedures to prevent contamination, but it is about preventing introduction of organisms rather than describing a process that eliminates every organism and spore.

Therefore, the term that describes techniques that eliminate all microorganisms and spores is sterilization.
