front 1 What method of microbial control completely destroys all forms of microbial life? | back 1 Sterilization |
front 2 What is commercial sterilization? | back 2 Limited heat treatment, destroys pathogens but not all bacteria (killing C. botulinum endospores) |
front 3 What method destroys the vegetative cells on a surface? | back 3 Disinfection |
front 4 What is a disinfectant? | back 4 Chemical treatment used to disinfect inanimate objects (removal of pathogens) |
front 5 What method is treatment of living skin or tissue to kill microorganisms (removal of pathogens from living tissue)? | back 5 Antisepsis |
front 6 What is physical removal of microbes (alcohol swab, soap) - as in cleaning the skin prior to injections? | back 6 Degerming |
front 7 What is sepsis? | back 7 Refers to microbial contamination |
front 8 What is asepsis? | back 8 The absence of significant contamination |
front 9 What prevents microbial contamination of wounds? | back 9 Aseptic surgery techniques |
front 10 What is the systematic cleansing of inanimate objects to reduce the microbial count to a safe level (for public health, used in restrooms, kitchens)? | back 10 Sanitize |
front 11 What is bactericidal? | back 11 (-cidal, to kill); kill all bacteria |
front 12 What is bacteriostatic? | back 12 (-static, to stop); halt (inhibit) the growth of bacteria for as long as the inhibitory substance is present; if inhibitor is removed, growth begins again |
front 13 Microbial death (same as growth) occurs how? | back 13 Killing in a population is not instantaneous, it occurs exponentially |
front 14 What does the effectiveness of antimicrobial treatment depend on? | back 14 Number of microbes Environment (organic matter, temperature, biofilms) Time of exposure (need time for disinfectant to work, then wipe) Microbial characteristics (if unfavorable conditions then will make endospore) |
front 15 What is thermal death time (TDT)? | back 15 The time at a given temperature in which all the microorganisms in a liquid culture will be killed. |
front 16 What is | back 16 no data |
