Which process destroys all bacteria except spores?

Which process destroys all bacteria except spores?

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

Answer: (B)

Disinfection is the level of microbial control that aims to destroy most pathogens on inanimate surfaces, but spores tend to survive. Bacteria have two forms: active, vegetative cells that are relatively easy to kill, and spores that are highly resistant. Sterilization would wipe out all forms of life, including spores, so it wouldn’t fit the idea of “destroying all bacteria except spores.” Sanitation lowers the overall microbial load without guaranteeing the destruction of all pathogens, and asepsis is about preventing contamination rather than a specific killing process. So, the description aligns with disinfection: it eliminates many bacteria, but spores remain. Some disinfectants can be sporicidal under certain conditions, but in general disinfection does not guarantee killing spores.
