micro chapter 11

what are the 11 germicidal categories

what germicidal category includes bromine, iodine, and chlorine

what halogens are hypocholrites that denature proteins by disrupting disulfide bonds

what halogen is intermediate level and includes water, sewage, wastewater, and inanimate objects

what halogens are iodophors the interfere with disulfide bonds of proteins

what halogen is intermediate level include milder medical and dental degermine agaents, disinfectants, and ointements

what germicidal category disrupt cell walls and membranes and precipitate proteins

what germicidal category is low to intermediate level include bactericidal, fungicidal, virucidal, not sporicidal

what germicidal category includes lysol and triclosan-antibacterial additive to soaps

what germicidal category is a surfactant and protein denaturant with broad microbicidal properties

what germicidal category are low to intermediate levels, include hibiclens and hibitane

what germicidal category are used as skin degeming agents for preoperative scrubs, skin cleaning, and burns

what germicidal category acts as surfactants dissolving membrane lipids and coagulating proteins of vegetative bacterial cells and fungi

what germicidal category are intermediate level include, ethyl and isopropyl in solutions of 50-95%

what germicidal category gram-alcohols=drinking and isopropanol=rubbing alcoho; primary not pure 70%alcohol and 30% water= best

what germicidal category produce highly reactive hydroxyl-free radicals that damage protein and DNA while also decomposing to O2 gas- toxic to anaerobes

what germicidal category antiseptic at low concentrations; strong solutions are sporicidal

what germicidal category can be toxic to anerobic bacteria 3%=use on skin 30%=eat skin away OH- very reactive

what germicidal category kill by alkylating proteins and DNA (alkylating=aldehyde reacts with certain molecules to change structure)

what aldehydes is in 2% solution (cidex) used as sterilant for heat sensitive instruments HIGH LEVEL

what aldehyde is a disinfectant, preservative, toxicity limits use; formalin- 37% aqueous solution; intermediate to high level

what germicidal category are strong alkylating agents, chemicals are explosive hense why contained in chambers

what germicidal category are high level and include ethylene oxide and propylene oxide

what germicidal category sterilize and disinfect plastics and prepackaged devices, food

what germicidal category has quaternary ammonia compounds that act as surfactants that alter membrane permeability of some bacteria and fungi

what germicidal category are very low level and molecule is amphipathic which can disrupt membrane

what germicidal category mechanically remove soil and grease containing microbes

what germicidal category are solutions of silver and mercury kill vegetative cells in low concentrations by inactivating proteins

what germicidal category are low level include merthiolate, silver nitrate, silver

what germicidal category have oligodynamic action (small concentration of + ions on living things) can be toxics, some microorganisms can develope resistance

what germicidal category are very active against gram-positive species of bacteria and various fungi

what germicidal category are low level, narrow spectrum of activity; sometimes used for antisepsis and wound treatment

what germicidal category are at low level of activity

what germicidal category have orgaic acids prevent spore germination and bacterial and fungal growth

what germicidal category acetic acid inhibits bacterial growth, propionic acid retards molds, lactic acid prevents anaerobic bacterial growth, benzoic and sorbic acid inhibit yeast
