High-level disinfectant: A germicide that killsall microbial pathogens except large numbers of bacterial spores
Intermediate-level disinfectant: A germicide that kills all microbial pathogens except bacterial endospores
Low-level disinfectant: Agermicide that kills most vegetative bacteria and lipid-enveloped or medium-size viruses
Antisepsis: Use of chemical agents on skin or other living tissue to inhibit or eliminate microbes; nosporocidal action is implied
Sterilization: Use of physical procedures or chemical agents to destroy all microbial forms, including bacterial spores
Disinfection: Use of physical procedures or chemicalagents to destroy most microbial forms: bacterial spores and other relatively resistant organisms (e.g.,
mycobacteria, viruses, fungi) may remain viable disinfectants are subdivide into high-,intermediate-, and low-level agents
