Document Summary
Terms: sterilization- to remove/kill all microorganisms in a material. Sterile- endospores also removed, vegetative cells are existent: disinfection- reduction of number of pathogens where they pose no danger, antiseptic- chemical agent to be used externally on living tissue to destroy microorganisms or to inhibit growth. C. 1. ex/ rubbing alcohol, hydrogen peroxide: disinfectant- chemical agent used on inanimate objects to destroy microorganisms. most do not kill spores. D. 1. ex/ alcohol: sanitizer- chemical agent typically used in food-handling equipment and eating utensils to reduce bacterial numbers. E. 1. ex/ soap and detergent: bacteriostatic agent- inhibits growth of bacteria, germicide- kills microbes, inhibits growth of others, bactericide- agent that kills bacteria. Most do not kill spores: viricide- inactivates virus, fungicide- an agent that kills fungi, sporocide- agent that kills bacterial endospores or fungal spores, kill curve- kill at particular rate. Definite proportion of the organisms die in a given time interval. Fewer organisms present shorter the time needed to achieve sterility.
