|
Sterilization |
Destruction or removal of all forms of microbial life, including endospores but with the possible exception of prions.
Example steam under pressure or sterilizing gas (ethylene oxide) |
|
|
Disinfection |
Disinfection of vegetative pathogens on inanimate objects.
Example Physical or chemical methods. |
|
|
Antisepsis |
Destruction of vegetative pathogens on living tissue.
Example Chemical antimicrobials. |
|
|
Germicide |
A biocide that kills microorganisms. Name of treatments that kills microbes and end with -cide (kill). Example Fungicide kills fungi |
|
|
Bacteriostasis |
Treatments that inhibits the growth and multiplication of bacteria. Names ending with -stat or -stasis meaning to stop or steady. If bacteriostatic agent is removed, growth might resume. |
|
|
Asepsis |
The absence of significant contamination. Aseptic techniques in surgery minimizes contamination from the instruments, operating personnel and patient. |
|
|
Degerming |
Removal of microbes from a limited area such as, skin around an injection site.
Example Mechanical moving by an alcohol-soaked swab. |
|
|
Sanitization |
Treatment is intended to lower microbial counts on eating/drinking utensils to save public levels.
Example High temperature washing or dipping into chemical disinfectant. |
|
|
Factors that influence effectiveness of antimicrobial treatments. |
The number of Microbes. The more microbes the longer it takes to eliminate.
Environmental influences Most disinfectants work better in warm Solutions.
Time of exposure Requires extended exposure to affect more resistant microbes are endospores.
Microbial characteristics Choosing the correct chemical physical control methods. |
|
|
Effects on microbial control agents |
Alteration of membrane permeability (things make it through membrane), damage to protein (enzymes) and nucleotides (DNA and RNA) Heat Moist heat sterilization Dry heat sterilization Filtration radiation |
