(dis'in-fek'shŭn),
Destruction of pathogenic microorganisms or their toxins or vectors by direct exposure to chemical or physical agents.

(dis-in-fek'shŭn)
Destruction of pathogenic microorganisms or their toxins or vectors by direct exposure to chemical or physical agents.

disinfection

To use chemical substances to kill bacteria and other infecting agents outside the body or on the skin. Such substances include hexachlorophene, benzalkonium, cetrimide, phenol, merthiolate and various alcohols.

disinfection

the use of a DISINFECTANT to destroy, inactivate or remove MICROORGANISMS that are likely to cause infection, spoilage or other undesirable effects in an inanimate object. Disinfection does not normally involve STERILIZATION.

disinfection

The process or act of destroying pathogenic microorganisms. However, certain bacterial spores may survive and germinate which could lead to contamination. See antiseptic; sterilization; surfactant.
chemical disinfection A method of disinfecting soft contact lenses, using solutions containing either a preservative or hydrogen peroxide. Preservatives include chlorhexidine, thimerosal (very rarely used nowadays) and more commonly nowadays the preservatives with larger molecules which cannot penetrate into the lens matrix of soft contact lenses, such as the biguanide polyhexanide (polyaminopropyl biguanide or polyhexamethylene biguanide). Hydrogen peroxide has a broad-spectrum efficacy against bacteria, fungi and viruses. It must, however, be neutralized before the lens can be worn. Rigid gas permeable contact lenses are disinfected with a preservative such as chlorhexidine, benzalkonium chloride, polyhexanide and polixetonium chloride. Failure to disinfect contact lenses may lead to microbial keratitis. Disinfectants for contact lenses have to pass FDA and International Organization for Standardization (ISO) tests to be approved. They must be effective against three specific bacteria (Pseudomonas aeruginosa, Staphylococcus aureus and Serratia marcescens) and two fungi (Candida albicans and Fusarium solani). See neutralization.
heat disinfection A method of disinfecting soft contact lenses, based on heating the lens to a temperature of at least 80º for 10 minutes. This is achieved in specially manufactured heating units in which the lenses are kept in physiological saline solution. However, repeated boiling of soft lenses may cause some degradation of the lens material, and tear mucoproteins that have not been previously removed with a surface cleaning agent tend to become coagulated on the lens surface.

(dis-in-fek'shŭn)
Destruction of pathogenic microorganisms or their toxins or vectors by direct exposure to chemical or physical agents.
