What term describes chemical agents that destroy all bacteria, fungi, and viruses, but not spores, on surfaces?

• A. Antiseptics
• B. Sterilants
• C. Sanitizers
• D. Disinfectants

Answer: (D)

Disinfectants are chemical agents used on inanimate surfaces to kill or greatly reduce bacteria, fungi, and viruses. They’re designed to lower the presence of these pathogens on surfaces to help prevent disease transmission, but they do not guarantee destruction of bacterial spores. Sterilants, in contrast, aim to destroy all microorganisms including spores, typically through more rigorous processes. Antiseptics are used on living tissue, not surfaces, and sanitizers reduce microbial counts to safe levels without necessarily eradicating all pathogens. So, for a surface-disinfecting context where spores aren’t targeted, the correct term is disinfectants.
