What term describes a clean technique that reduces the number of microorganisms but does not eradicate spores?

Disinfection Sterilization Medical Asepsis Surgical Asepsis

Correct Answer:

Medical Asepsis

Explanation:

Medical asepsis is the clean technique used to reduce the number of microorganisms and limit their transmission, but it does not eliminate spores. Spore-forming organisms are highly resistant and require sterilization methods (like autoclaving or chemical sterilants) to destroy them. This is why medical asepsis fits the description best: it lowers microbial load without guaranteeing the complete eradication of spores. By contrast, disinfection targets many pathogens on surfaces but may not kill all spores, sterilization eliminates all microorganisms including spores, and surgical asepsis uses sterile technique to maintain a completely germ-free field for invasive procedures.
