Which term describes a process that eliminates many or all microorganisms, with the exception of spores, from inanimate objects?

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

Answer: (A)

Disinfection reduces or eliminates most pathogenic microorganisms on inanimate surfaces, but spores are typically not destroyed by this process. This distinction matters because disinfection is aimed at making surfaces safer to touch or use by lowering the microbial load, rather than achieving complete sterility. Sterilization, by contrast, would kill all microorganisms including spores, which is why it’s used for instruments and areas that must be completely free of life. Antisepsis is intended for living tissue to prevent infection, not for inanimate objects. Sanitization lowers microbial levels to a safe standard but does not guarantee the elimination of all pathogens. So the description fits disinfection: it targets a broad reduction of microbes on non-living surfaces, with spores usually surviving.
