Control of Microorganism Flashcards
It refers to the destruction of all forms of life, including bacterial spores.
Sterilization
It refers to a process that eliminates a defined scope of microorganisms, including some spores.
Disinfection
A substance applied to the skin for the purpose of eliminating or reducing the number of bacteria present is referred to as?
Antiseptic
A general term describing a chemical agent, usually broad- spectrum, that inactivates microorganisms.
Biocide
A specific term referring to the property by which a biocide is able to inhibit bacterial multiplication; multiplication resumes upon removal of the agent.
Bacteriostatic
A specific term referring to the property by which a biocide is able to kill bacteria.
Bactericidal
A physical or chemical process that completely destroys or removes all microbial life, including spores.
Sterilization
Products or biocides used to kill microorganisms on inanimate objects or surfaces.
Disinfectants
Characterized by the presence of pathogenic microbes in living tissue.
Septic
A biocide or product that destroys or inhibits the growth of microorganisms in or on living tissue.
Antiseptic
Characterized by the absence of pathogenic microbes.
Aseptic
The prevention of multiplication of microorganisms in formulated products, including pharmaceuticals and foods.
Preservation
Naturally occurring or synthetic organic compounds which inhibit or destroy selective bacteria, generally at low concentrations.
Antibiotics
Disinfectants are generally used at room temperature.
[temperature]
20° to 22° C
It can be considered as a community of bacteria or other microorganisms.
Biofilms
Heat under steam pressure, used in autoclaves.
Moist heat
Method of choice for heat-stable objects.
[heat]
Moist heat
It requires much longer exposure times and higher temperatures than moist heat.
[heat]
Dry heat
Used for heat-stable substances that are not penetrated by moist heat.
[heat]
Dry heat
Commonly used to sterilize glassware.
[heat]
Dry heat
Achieve disinfection but not sterilization; these methods do not eliminate spores.
Boiling and pasteurization
It used mostly in the food industry.
Pasteurization
Radiation, in the form of gamma rays or electron beams.
Ionizing radiation
Radiation in the form of ultraviolet rays.
Nonionizing radiation
