The use of heat to kill microorganisms except spores is called what?

• A. Disinfection
• B. Sterilization
• C. Thermal disinfection
• D. Antiseptic treatment

Answer: (C)

The correct answer is thermal disinfection, which specifically refers to the application of heat to eliminate harmful microorganisms, with the notable exception of bacterial spores. This process typically involves water or steam at temperatures that are effective against a wide range of pathogens, making it suitable for surfaces, equipment, and materials that cannot withstand more extreme conditions required for full sterilization. Disinfection, while similar, may not always involve heat and usually implies killing or inhibiting the growth of microorganisms but does not guarantee the destruction of all spores. Sterilization goes a step further by ensuring that all forms of microbial life, including spores, are eradicated. Antiseptic treatment typically pertains to substances applied to living tissue to reduce the risk of infection, rather than a method of disinfection or sterilization through heat. In the context of healthcare or environments handling sterile goods, understanding the nuances between these terms is crucial for maintaining proper infection control practices.
