|
Antisepsis:
define, give examples. |
Reduction in the number of microorganisms and viruses, particularly potential pathogens, on living tissue.
Note: Antiseptics are frequently disinfectants whose strength has been reduced to make them safe for living tissues. |
Examples: Iodine; alcohol. |
|
Asceptic:
define, give examples. |
Refers to an environment or procedure free of pathgenic contaminants.
Note: Scientists, lab techs, and health care workers routinely follow standardized aseptic techniques. |
Preparation of surgical field; handwashing; flame sterilization of lab equipment |
|
-cide; -cidal:
define, give examples. |
Suffixes indicating destruction of a type of microbe.
|
Bactericide; fungicide; germicide; virucide. Note: Germicides include ethylene oxide, propylene oxide, and aldehydes. |
|
Degerming:
define, give examples. |
Removal of microbes by mechanical means.
Note: Chemicals play a secondary role to the mechanical removal of microbes. |
Handwashing; alcohol swabbing at site of injection. |
|
Disinfection:
define, give examples. |
Destruction of most microorganisms and viruses on nonliving tissue.
Note: The term is used primarily in relation to pathogens. |
Phenolics; alcohols; aldehydes; soaps. |
|
Pateurization:
define, give examples. |
Use of heat to destroy pathogens and reduce the number of spoilage microorganisms in foods and beverages.
Note: Heat treatment is brief to reduce alteration of taste and nutrients; microbes still remain and eventually cause spoilage. |
Pasteurized milk and fruit juices. |
|
Sanitation:
define, give examples. |
Removal of pathogens from objects to meet public health standards.
Note: Standards of sanitation vary among governmental jurisdictions. |
Washing tableware in scalding water in restaurants. |
|
-stasis; -static.
define, give examples. |
Suffixes indicating inhibition, but not complete destruction, of a type of microbe.
|
Bacteriostatic; fungistatic; virustatic. Note: Germistatic agenst include some chemicals, refrigeration, and freezing. |
|
Sterilization:
define, give examples. |
Destruction of all microorganisms and viruses in or on an object.
Note: Typically achieved by steam under pressure, incineration, or ethylene oxide gas. |
Prepearation of microbiological culture media and canned food. |
