Water vapor: This method allows the eradication of viruses, bacteria such as tuberculosis bacteria Mycobacterium tuberculosis and heat-resistant spores. A device called an autoclave is used, where high temperature, pressure and a prolonged time are combined: 134 ° C at a pressure of 2 kPa for 3 minutes or 121 ° C at a pressure of 1 kPa for 15 min.

Several sterilization processes are used: Sterilization is the process of eliminating all microbes, including bacteria, spores, viruses, and fungi. Some viruses and prions are not affected by disinfectants. Low disinfectants: they are active only against some viruses and bacteria.Intermediate disinfectants: they are active against microbes but not against bacterial spores.High activity disinfectants: destroy all microbes and spores, except when they are in large quantities.It is the process of eliminating microorganisms on objects using chemical agents known as disinfectants.ĭisinfectants are classified according to their activity in: Some factors should be considered for the choice of the appropriate antiseptic:

#ASEPSIS DEFINITION SKIN#
Microorganisms, such as bacteria and fungi, normally inhabit the skin and mucous surfaces (such as inside the mouth).
