What is a chemical germicide capable of destroying all microorganisms, including bacterial spores, classified as?

A chemical germicide that can destroy all microorganisms, including bacterial spores, is classified as a sterilant. Sterilants are the most potent class of germicides, essential for achieving sterility by eliminating all forms of microbial life on surfaces or instruments. This property is critical in healthcare settings, especially in the processing of surgical instruments and devices that come into contact with sterile tissues.

In contrast, other classifications bserve different levels of efficacy. A low-level disinfectant is effective primarily against vegetative bacteria and some viruses but does not kill spores or certain resistant pathogens. High-level disinfectants can kill most microorganisms, but may not achieve complete sterilization. Understanding these classifications helps determine proper cleaning and disinfecting protocols in medical settings to ensure patient safety and infection control.
