Most importantly, antisepsis and disinfection no destroy all forms of microbial life whereas sterilization does. In addition, sterilization destroys spores completely while both antisepsis disinfection may not destroy all spores. Antisepsis is a chemical method whereas disinfection and sterilization can include both chemical and physical methods.
What is the difference between disinfection and sterilization?
Disinfection is the process of eliminating disease-causing microbial life on inanimate objects. Sterilization, in contrast, is the process of destroying all forms of microbial life from a given product or a surface either in the vegetative or spore state.

Antisepsis, disinfection, and sterilization are three processes that help us to remove or destroy microorganisms. 1. Overview and Key Difference 2. What is Antisepsis
What is antiseptics?
The destruction or prevention of growth of most pathogens on living tissue is called antisepsis. Note that like disinfection, most, but not all, microorganisms are killed, and unlike both sterilization and disinfection, antisepsis refers to living tissue. A substance that performs this process is known as an antiseptic.
How to compare disinfectant effectiveness?
As a morbid metaphor, you can compare the effectiveness of a disinfectant on a certain microorganism to the way a murderer (the disinfectant) may try to kill a person (the microorganism). For example, someone may try to kill a person by dropping them into the sea, far from shore, in the hopes that the person will drown. But if that person is a good swimmer, then that method of killing won't be as effective as frying that person to death instead. That's why you have to be careful in which disinfectant you use to kill a certain type of microorganism.
Why is sterilization important?
That's because if they have even one little microorganism on it and that microorganism jumps off of the surgical instrument and into the cut the surgeon makes into your body, you can get a life-threatening infection!

Why is it important to clean off dirt and debris before using a disinfectant?
That's why prior to disinfecting something like a toy that was lying around outside, it's important to clean off any dirt and debris you can see with your naked eye prior to using a disinfectant that kills the microorganisms that you cannot see. Other factors, such as the type of surface being disinfected, the length of time the disinfectant is used for, and the way the disinfectant is applied may also influence its effectiveness.

The purpose is to kill enough germs so the risk of infection is extremely low. Decontamination is different from cleaning, which can get rid of dust and dirt but may only remove some of the germs that are present.
Why is it important to clean before disinfecting?
The importance of cleaning. While cleaning itself doesn’t kill all germs, this can be an important first step before disinfecting or sterilizing.

What is the difference between sterilization and disinfection?
Sterilization and disinfection are both decontamination processes, but where sterilization is the process of eliminating all harmful microorganisms from objects and surfaces, disinfection means to eliminate most harmful microorganisms, but this doesn’t include spores. Both disinfection- and sterilization procedures use chemical or physical agents to destroy pathogens and to ensure that pathogenic microorganisms are not transmitted to patients. In hospitals, critical objects that make contact with sterile tissue require sterilization before use.
Why is sterilization important in the veterinary industry?
Sterilization on the other hand is a chemical or physical process that eliminates all forms of microbial life. 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. Bacteria, fungi and viruses can’t stand up to sterilization.
Do you sterilize surgical instruments?
Once a surgical instrument for instance has been sterilized, you can say that all micro-organisms have been removed and that when the sterilizer has done its job, nothing survives.
Does filtration kill bacteria?
Different disinfectants have different target ranges and can’t kill all micro-organisms. Filtration, which is one method of disinfecting, doesn’t kill bacteria.
