Sterilization is distinct from disinfection, sanitization, and pasteurization, in that those methods reduce rather than eliminate all forms of life and biological agents present. After sterilization, fluid or an object is referred to as being sterile or aseptic .
Disinfection uses liquid chemicals on surfaces and at room temperature to kill disease-causing microorganisms. Ultraviolet light has also been used to disinfect the rooms of patients infected with Clostridioides difficile after discharge. [14] Disinfection is less effective than sterilization because it does not kill bacterial endospores. [15]
Ultraviolet light fixtures are often present in microbiology labs, and are activated only when there are no occupants in a room (e.g., at night). [citation needed] Heat treatment can be used for disinfection and sterilization. [42]

Hand scrubbing procedure for surgery. Asepsis is the state of being free from disease-causing micro-organisms (such as pathogenic bacteria, viruses, pathogenic fungi, and parasites). [1]
Sterile dental instruments from hospital central supply (barcoded label indicating sterilization date, expiry date and contents). The central sterile services department (CSSD), also called sterile processing department (SPD), sterile processing, central supply department (CSD), or central supply, is an integrated place in hospitals and other health care facilities that performs sterilization ...
Various UV-emitting devices can be used for SARS-CoV-2 disinfection, and these devices may help in reducing the spread of infection. [102] SARS-CoV-2 can be inactivated by a wide range of UVC wavelengths, and the wavelength of 222 nm provides the most effective disinfection performance. [102] Disinfection is a function of UV intensity and time.
Tyndallization is a process from the nineteenth century for sterilizing substances, usually food, named after its inventor John Tyndall, that can be used to kill heat-resistant endospores.
