Sterilization and Disinfection

The primary objective of sterilization is to completely eliminate all microorganisms from an object or surface.
A sterile object is distinguished from a non-sterile one by the complete absence of all microorganisms, including bacterial spores.

Aseptic Measures

In aseptic measures, the method used to fight pathogens in or on living tissue is antimicrobial chemotherapy.

Disinfection

The main purpose of the disinfection procedure is to reduce the number of microorganisms on an object or surface to a level that is considered safe.

Gaseous Chemicals

Gashouse chemicals like formaldehyde and ethylene oxide are used to sterilize heat-sensitive pharmaceuticals.

Filtration Sterilization

The method used to sterilize heat-sensitive pharmaceuticals is filtration sterilization using ultrafine filters.
One advantage of ultrafine filters in filtration sterilization is that they can remove very small particles and microorganisms from liquids.

Radiation Sterilization

Ionizing radiation, which consists of electromagnetic waves produced by nuclear disintegration, is used to sterilize certain objects.

Disinfectants

Isopropyl alcohol is quite effective against bacteria and fungi, but less so against viruses.
Iodine is a halogen suitable for use as a disinfectant, showing a generalized microbicidal effect, including killing spores.
Hydrogen peroxide is used as a mild antiseptic to disinfect mucosa, skin, or wounds, based on its chemical activity involving the splitting off of oxygen.
One advantage of surfactants as disinfectants is their ability to reduce surface tension, making it easier to clean surfaces.

Test your knowledge about sterilization and disinfection processes. This quiz covers the definitions, methods, and importance of sterilization and disinfection in preventing the spread of microorganisms.
