Micro Chapter 11 pt 1
Is the item reusable or disposable? Is it safe? Is sterilization needed? Will it penetrate effectively? Can it withstand physical or chemical treatments? Is it cost and labor-efficient?
Which of the following should be considered when initially choosing a method of microbial control?
blank 1 : sterilization blank 2 : disinfection
_________ is the destruction of all microbial life - whereas what destroys most microbial life, thus reducing contamination on inanimate surfaces
sterilization
a process that completely removes or destroys all viable microorganisms, including viruses, from an object or habitat that is referred to as
true
a sporicide agent can also be sterilant because it can destroy bacterial endospores and leave an object free of all life
all viable microorganisms and viruses
a sterile object is free of
sporicidal
agent can also be a sterilant because it can destroy bacterial endospores and leave an object free of all life
uniform populations of like microbes
all of the following describe the typical microbial population targeted by antimicrobial drugs EXCEPT
chemical
antiseptics are what type of agents applied to the skin to inhibit vegetative bacterial cells
bacteriostatic
any process or agent that inhibits bacterial growth is referred to as what
antiseptics
chemical agents applied directly to body surfaces to inhibit vegetative pathogens
blank 1 : human blank 2 : animal
disinfectants are normally used only on inanimate objects because they can be toxic or harmful to __________ and other __________ tissues
only vegetative bacterial cells
disinfection destroys
sanitization
is a decontamination technique that mechanically removes microorganisms and debris from inanimate objects to reduce contamination to safe levels
degermation
is the physical removal of surface oils, debris and soil from skin to reduce the microbial load
generally reserved for inanimate objects only necessary for certain groups of microbes
sterilization is
is highly dangerous and impractical
sterilization of the skin
asepsis
term referring to a condition free of pathogenic microorganism or a procedure or process designed to prevent entry of infectious agents
false
the characteristics of a microbial population targeted for control do not include microbes with variable resistance
antisepsis
the destruction of most microbes using chemicals on a living surface such as the skin
protein function the cell membrane the cell wall nucleic acid synthesis
the four general cellular targets of antimicrobial agents are
protein
the four general cellular targets of antimicrobial agents are the cell wall, the cell membrane, nucleic acid synthesis, and what
bacterial vegetative cells enveloped viruses
the microbial agents that are lease resistant to physical and chemical control methods include
food spoilage disease
the primary targets of microbial control are microorganism that cause what (2)
true
the primary targets of microbial control are microorganisms that cause infection or spoilage
disinfection
the use of physical process or a chemical to destroy vegetative pathogens but not bacterial endospores, usually on inanimate surfaces
sepsis
what is defined as growth of microorganisms in the blood or other tissues
-static
what suffix is used to indicate the inhibition of growth of microorganisms
bacterial endospores
which microbial agent is the most resistant to physical & chemical control methods
