Document Summary
Control of microbial growth: disinfectants and antiseptics: method. There are three approaches for the control of microbial growth: chemical: disinfectants and antiseptics, physical: heat, ultraviolet, irradiations, mechanical elimination: cleaning, ltration, terminology. Cleaning: the elimination of visible adherent dirt (blood, proteins, and debris), dust or other foreign matter by manual or chemical processes. Does not infer the presence or absence of microorganisms (cleanliness does not equal sterility) Disinfection: the use of chemical or physical agents to kill or inhibit the growth of microorganisms. Germicides: chemical products which can be used on either animate (living) or inanimate things. Contamination: non-intentional presence (intruder) of a microorganism. Decontamination: operation used to reduce or eliminate a contaminant. Bacterial spores: disinfectants and antiseptics: ideal characteristics. Oxidation of functional groups (remove electrons, results in inactivation of enzymes) Types of chemical agents: phenol and phenolic compounds (benzene ring with oh)
