What is the primary purpose of the disinfecting process?

• A. Destroy microorganisms
• B. Sterilize all materials
• C. Remove organic matter
• D. Inactivate enzymes

Answer: (A)

Disinfection is aimed at reducing the risk of infection by destroying disease-causing microorganisms on inanimate surfaces. It lowers the microbial load to safe levels, but it does not guarantee complete elimination of every organism—that would require sterilization. Cleaning, which removes organic matter, often comes first because organic debris can shield microbes and reduce disinfectant effectiveness. While disinfectants may denature enzymes as part of their chemical action, the main goal is the destruction of microorganisms themselves, not enzyme inactivation. Sterilization would be used when a completely sterile condition is required. Thus, the primary purpose is to destroy microorganisms.
