Shingles is an infection by the herpes zoster virus, which also causes chicken pox. This happens in people who have had chicken pox and the virus present in the nerve reactivates later on in life. Shingles causes a painful rash on one side of your body and can affect your ears.
Moist heat sterilization is a technique that uses heated water and superheated steam to disinfect contaminated materials, such as culture media, surgical instruments, glassware and other non-thermally sensitive items.
Moist heat destroys microorganisms by the irreversible denaturation of enzymes and structural proteins. The temperature at which denaturation occurs varies inversely with the amount of water present. Sterilization in saturated steam thus requires precise control of time, temperature, and pressure.
