What are the sterilization and disinfection?
Sterilization describes a process that destroys or eliminates all forms of microbial life and is carried out in health-care facilities by physical or chemical methods. Disinfection describes a process that eliminates many or all pathogenic microorganisms, except bacterial spores, on inanimate objects (Tables 1 and 2).
What is the aim of successful disinfection?
Disinfection is the treatment of surfaces/equipment using physical or chemical means such that the amount of microorganisms present is reduced to an acceptable level. Disinfection reduces the amount of remaining microorganisms.
What is an example of antisepsis?
Commonly used antiseptic groups include alcohols, quaternary ammonium compounds, chlorhexidine and other diguanides, antibacterial dyes, chlorine and hypochlorites, inorganic iodine compounds, metals, peroxides and permanganates, halogenated phenol derivatives and quinolone derivatives.
Why disinfection is done?
Disinfection is the treatment of surfaces/equipment using physical or chemical means such that the amount of microorganisms present is reduced to an acceptable level. Disinfection reduces the amount of remaining microorganisms. Application of the right type of agent is important to achieve the desired chemical effect.
Which is the first step in disinfection and sterilization?
Cleaning must always precede high-level disinfection and sterilization. Antiseptics are essential to infection prevention as part of a hand hygiene program, as well as other uses, such as surgical hand antisepsis and preoperative skin preparation. Keywords: Antisepsis; Disinfection; Sterilization.

How are antiseptics used in the treatment of infection?
Antisepsis is the process of preventing the infection by inhibiting or arresting the growth and multiplication of germs (infectious agents) on living tissues. Antiseptics are the antimicrobial agents used in antisepsis.
Why is it important to clean and decontaminate sterilization instruments?
Cleaning reduces the bioburden and removes foreign material (organic residue and inorganic salts) that interferes with the sterilization process. Cleaning and decontamination should be done as soon as possible after the items have been used as soiled materials become dried onto the instruments.
