~Definition of Microbial Control Terms~ |
The following terms are used to describe the Processes and Agents employed in controlling micro-organism.
(From 'MICROBIOLOGY' by Pelczar, Reid and Chan published by TMH)
STERILISATION: The process of destroying all forms of microbial life. A sterile object, in the microbiological sense, is free of living micro-organisms. The terms sterile, sterilise and sterilisation therefore refer to the complete absence or destruction of all micro-organisms and should not be used in a relative sense. An object or substance is sterile or non- sterile: it can never be semi-sterile or almost sterile.
DISINFECTANT: An agent, usually a chemical, that kills the growing forms but not necessarily the resistant spore forms of disease producing micro-organisms. The term commonly applied to substances used on inanimate objects. Disinfection is the process of destroying infectious agents.
ANTISEPTIC: A substance that opposes sepsis, or prevents the growth or action of micro-organisms either by destroying micro-organisms or by inhibiting their growth and activity. Usually associated with substances applied to the body.
SANTISER: An agent that reduces the microbial population to safe levels as judged by public health requirements. Usually it is a chemical agent that kills 99.9% of the growing bacteria. Sanitisers are commonly applied to inanimate objects and are generally employed in the daily care of equipment and utensils in dairies and food plants and for glasses, dishes and restaurant utensils. The process of disinfection would produce sanitation.
GERMICIDE (Microbicide): An agent that kills the growing forms but not necessarily the resistant spore forms of germs. In practice a germicide is almost the same thing as a disinfectant, but germicides are commonly used for all kinds of germs (microbes), for any application.
BACTERICIDE: An agent that kills bacteria (adjective bactericidal), Similarly the terms fungicide, viricide and sporicide refer to agents that kill fungi, viruses and spores respectively.
BACTEROSTATASIS: A condition in which the growth of bacteria is prevented (adjective bacteriostatic), Similarly, fungistatic describes an agent that stops the growth of fungi. Agents that have in common the ability to inhibit growth of micro-organisms are collectively designated microbistatic agents.
ANTIMICROBIAL AGENT: One that interferes with the growth and activity of microbes. In common usage the term denotes inhibition of growth, and with reference to specific groups of organisms such terms as antibacterial or antifungicidal are frequently employed. Some antimicrobial agents are used to treat infections, and are called therapeutic agents.
