Which microorganisms are targeted by thermal disinfection?

• A. All microorganisms including spores
• B. Only bacterial spores
• C. Most microorganisms excluding spores
• D. Only viruses

Answer: (C)

Thermal disinfection specifically targets most microorganisms, effectively eliminating bacteria, fungi, and some viruses through the application of heat. The primary aim of thermal disinfection is to reduce the number of viable pathogens to a level that is considered safe for handling instruments and surfaces. While thermal disinfection is quite effective against a wide range of microorganisms, it does not guarantee the destruction of bacterial spores, which are significantly more resistant to heat. This resistance means that while thermal disinfection is adequate for general disinfecting purposes, additional methods such as sterilization are necessary when dealing with spores. Thus, the option that asserts that thermal disinfection succeeds with most microorganisms, excluding spores, accurately reflects the capabilities and limitations of this method within the context of infection control and instrument safety.
