What is the difference between disinfection and sterilization?

Hospitals use sterilization on surgical tools. Each level can be achieved in many different ways. The process of sterilization kills all forms of microbial life, including fungi, spores, viruses and bacteria. Sterilization requires a higher level of technology. It destroys unicellular eukaryotes such as , fungi, bacteria, viruses, prions, and their spores.

They are so ubiquitous that the presence of many microbes causes undesirable consequences such as food spoilage and diseases. Sterilization is prevalent in food industry, medicine and surgical instruments. Sterilization is two modes; physical methods as well as chemical methods. Kills some bacteria and fungi while inactivating viruses. While disinfection does not need a very strict key points to be followed. X-rays, gamma rays, subatomic particles, or electron beams emit the low energy radiation for the required amount of time. Difference Between Sterilization and Disinfection Definition Sterilization refers to the total destruction of all microorganisms whether or not pathogenic and their spores, usually through the use of drastic methods while disinfection refers to the cleaning of something with chemicals to kill bacteria and other tiny living things that cause disease.

Some of the differences are listed below:- Disinfection Sterilization Definition It refers to the process that deactivates the disease producing microorganisms. Rubber, syringes, surgical equipment Dry Heat Sterilization Red heat, flaming, hot air Temperatures of at least 160 degrees Celsius for a variety of items including glass. For example: if you were concerned about Tuberculosis in a hospital waiting room. Physical method includes heat, radiation, and filtration. Sterilization is done using various methods such as applying heat, irradiation, chemicals and applying high pressure. This method is more effective on sporulating bacteria than just boiling.

Methods of Sterilization and Disinfection Disinfection is usually carried out by using disinfectants chemicals. This is important in the veterinary industry and health care industry when sterilization is required because highly resistant pathogens need to be destroyed and when medical equipment is going to be used in invasive procedures with animals or people. Boiling in water for 15min inactivates viruses and kills most vegetative bacteria. When should each be used? It is more practical to use disinfection in everyday life. In this article, we will discuss the differences between the two and will learn how to apply them properly.

Using the most thorough cleaning processes will still leaveUltrasonic Cleaner microorganisms on the surface of the item. Although both sterilization and disinfection describe microbial control, these techniques are applied in different cases. Physiochemical is a combination of physical and chemical method. Sterilization involves both chemical and physical methods.

However it has no on the spores. Sanitizers are the weakest of the antimicrobials. Pasteurization: Pasteurization is a process that kills pathogenic bacteria in liquid food. Combination of heat, chemicals, irradiation, high pressure and filtration. Clinical infectious diseases, 39 5 , 702-709.

To achieve sterility, a holding time of at least 15 minutes at 121 °C 250 °F or 3 minutes at 134 °C 273 °F is required. Pasteurization: Pasteurized products have a shorter shelf life compared to sterilized product Processing steps Example is milk Sterilized milk: Various processing steps are involved during milk sterilization are shown in figure 1. Difference Between Disinfection and Sterilization Difference Between Disinfection and Sterilization is easy to understand once you know the main aim behind it. Pasteurization: Pasteurization was developed by French scientist Louis Pasteur during the nineteenth century. The means used to fight them work like a specific key to a specific lock — one has to know what kind of microbes one is battling with in order to choose a weapon. While on the other hand sterilization is a process of decontamination in which all the kinds of microorganisms present on the surface of the equipment are eliminated and the object which has been cleaned is called as sterile.

It also provides significant benefits in time-savings and safety by minimizing handling by cleaning personnel. Based on the purpose of decontamination, either disinfection or sterilization can be opted. Status of cleanliness Disinfection Adequate cleanliness Sterilization Absolute or extreme cleanliness 4. Steam, heating, chemical sterilization, radiation sterilization, sterile filtration. Heat, chemicals, irradiation, high pressure, and filtration.

Sterilization Heat, radiation, chemical, filtration Used to kill all microorganisms, viruses, and bacterial spores. Journal of orthodontic science, 5 1 , 14. Requires 10 minute contact time. Chemical Sterilization Bleach, hydrogen peroxide, ozone, ethylene oxide, glutaraldehyde and formaldehyde Concentrated chemicals used on objects that can be damaged by heat. Figure 1: Autoclave Machine Sterilization is important in the food processing industry, health care, and veterinary medicine which require destruction of microorganisms and their resting structures.

Typically disinfection is done with various chemicals and applied by hand. Figure 02: Disinfection It is important to understand that disinfection only reduces the number of microorganisms and does not completely eliminate them. Disinfectants may not kill all bacteria, viruses, fungi and spores. These processes involve mechanical controls of the air handling system and appropriately trained personnel or contractor to apply them in a safe and effective manner. Chemical Sterilization Certain items can be damaged by heat so chemical substances are used on electronics, fiber optics, and plastics. The use of an ultrasonic cleaner with detergents is able to dislodge fine particles from surfaces that may be inaccessible by physical scrubbing or brushing.
