Control of microbes Flashcards
process to promote and establish conditions which minimize or eliminate biohazards
Sanitation
a process of completely removing or destroying all life forms and their products including endospores
Sterilization
the destruction or inhibition of disease-causing microorganisms by chemical or physical means
Disinfection
the prevention or inhibition of the growth of causative microorganisms
Antisepsis
manual process by which microorganisms are removed from a surface
Scrubbing
form of sterilization that reduces waste to a more manageable amount and form ashes
Incineration
a form of incineration for human remains.
Cremation
What are the proper conditions for cremation to be fully sterile
1600F and many hours
What are the forms of dry heat sterilization?
-Incineration
-Cremation
-Hot air
will sterilize water that does not contain endospores and kill vegetative bacteria, most viruses, and fungi
Boiling
materials are incubated overnight to allow endospores to germinate then the objects are introduced to free-flowing steam the next day and this process is repeated
Free-Flowing steam
an autoclave machine is used to control microbial growth
Steam under pressure
What are the forms of moist heat sterilization?
-Boiling
-Free-flowing steam
-Steam under pressure
refrigeration or freezing (do not always destroy vegetative microbes or endospores)
Cold
a form of non ionizing radiation that can control microorganism growth.
-Must be directly exposed to be effective
-Some organisms are resistant
Ultraviolet light
