Antisepsis
|
The inhibition or killing of microorganisms on skin
or living tissue by use of a chemical antiseptic |
|
Antiseptic
|
Chemical used to inhibit or kill microorganisms on skin or living tissue.
|
|
Aseptic
|
Characteristic of an environment or procedure that is free of pathogenic contaminants
|
|
Aseptic technique
|
Methods of handling microbial cultures, patient specimens, and other sources of microbes in a way that prevents infection of the handler and others who may be
exposed. |
|
Bacteriocidal
|
A process or agent that kills bacteria.
|
|
Bacteriostatic
|
A process or agent that inhibits bacterial growth.
|
|
Degerming
|
Removal of microbes by mechanical means
|
|
Disinfectant
|
Physical or chemical agent used to inhibit or destroy most microorganisms and viruses on inanimate objects.
|
|
Disinfection
|
The use of physical or chemical agents to inhibit or destroy microorganisms on inanimate objects.
|
|
Sanitization
|
The process of disinfecting surfaces and utensils used by the public.
|
|
Sterilization
|
Any process that completely removes or destroys all viable microorganisms, including bacterial spores and viruses, from an object or habitat.
|
|
Sterile
|
Free of microbial contamination, including bacterial spores and viruses
|
|
A sample from the zone inhibition can be inoculated into nutrient broth. If bacteria grow in the broth, the action of the antibiotic was bacteriostatic not bacteriocidal
|
How would you tell if the action of an antibiotic is bactericidal or bacteriostatic?
|
|
Bacillus and Clostridium species both form highly‐resistant spores.
|
Why are Bacillus and Clostridium species considered more potentially resistant to disinfectants and antiseptics?
|
|
Hydrogen peroxide breaks down to form water and oxygen, and oxygen is toxic to anaerobes.
|
What is it about hydrogen peroxide that makes it effective in controlling the growth of vegetative anaerobes?
|
|
Bacterial spores
|
What would a chemical agent have to destroy in order to be called a sterilizer?
