Document Summary

Sterilization destruction or removal of all viable organisms (kills everything: pasteurization removes and kills the pathogens who are more sensitive to heat than other organisms. Disinfection killing, inhibition, or removal of disease-causing (pathogenic) organisms: not sterile, disinfectants. Sanitization reduction of microbial population to levels deemed safe (based on public health standards) Antimicrobial agents: use of chemicals to kill or inhibit growth of microorganisms within host tissue, takes place within the body. Germicide kills pathogens and many nonpathogens but not necessarily endospores. Avery welch mcb 2610 microbiology week 6-7 chapter 6b eliminating microbes. Germicides: static agents inhibit growth; does not necessarily kill it. Conditions influencing the effectiveness of antimicrobial agent activity. Population size: larger populations take longer to kill than smaller populations. Population composition: microorganisms differ markedly in their sensitivity to antimicrobial agents. Concentration or intensity of an antimicrobial agent: usually higher concentrations or intensities kill more rapidly, but not always, the best concentration for killing with ethanol is about 80%
