Document Summary
Sterilization: destruction or removal of all viable microbes. Wiping off food utensils to remove food fragments. Disinfection: killing, inhibition or removal of pathogenic microbes. Sanitization: reduce microbe population to levels deemed to be safe. Germicides: chemical that kills or inhibits microbe growth. Chemotherapy: use chemicals to kill or inhibit growth of microbes. Some things need moisture and some do not. Time at which sterilization of small amount of endospore containing material is achieved. Dry heat is less effective than moist heat. Some microbes killed by crystal disruption of cell membrane. Antimicrobial agent: natural or synthetic chemical that kills or inhibits growth of microbes. Minimal inhibitory concentration (mic): lowest concentration of drug that inhibits pathogen growth. Minimal lethal concentration (mlc): lowest concentration of drug that kills pathogen. Dilution susceptible test: smallest amount of agent needed to inhibit growth of test organism is mic.
