Document Summary
Controlling microbial presence and growth: four methods of microbial control, mechanical. Has to do with the removal or blocking of microbes. Filtration i. ii: masks are a mechanical barrier from covid, physical, chemical, biological. Has to do with other microbes / organisms. Can be used to remove offending microbes: not all bacteria is bad, we need bacteria to survive, four outcomes of microbial control, antisepsis. Always living tissue i. ii: weakest one, sanitation i. i. ii. i. ii. i. ii. iii. i. i. ii. i. Can apply to living tissue and non-living tissue: disinfection, sterilization. Boiling water is not sterilizing - it"s disinfection: mechanical removal methods, two types. Filtration: remove harmful bacteria and other microbes, not killing them, just filtering them out, water rinsing (liquid, removes microbes, physical control methods (cooper thinks of it as thermal, two types of physical control methods i. Heat: two types of heat - mechanism of thermal killing, dry heat i. ii. iii.
