-
Sterlization
- Process by destroying/removing all viable organisms on inanimate objects
- i.e. heat
-
Disinfection
- Destroy vegetative cells on inanimate surfaces
- i.e. chemical suspended in H2O- Bleach
-
Sanitization
- Cleansing technique to reach public health codes, mainly to reduce microbial load
- i.e. Soaps and detergents
-
Antiseptic
Chemicals applied to animate surfaces for prevention of infection and spread
-
Degermination
- Cleansing technique on animate surfaces
- -more rigorous
-
Decontamination
Destruction, removal or reduction in number of undersized microorganisms
-
Cide
Stasis
To kill
To stand still
-
Death of microorganism
Loss of reproductive capabilities even under optimal conditions
-

- Pneumonia
- HIV/AIDS
- Diarrhoea
- TB
- Malaria
- Measles
-
Chemotherapudic Agent
Any chemical used in the treatment, relief or prevention of a disease
-
Antimicrobial
All inclussive regardless of origin
-
Antibiotic
Naturally produced
-
Normal flora
Indiginous microorganisms- often have mutual or commercial associations with host
-
Trascient flora
Come and go, loose attachments
-
Resident flora
Flora that escape immune detection
-
True Pathogens
- Cause disease in a healthy host with normal immune defenses
- i.e. salmonella
-
Opportunistic Pathogens
- Host needs to have compromised immune system
- *Most fall under this category
-
Infection
Entry, establishment and multiplication of an organism host
-
Disease
Deviation from health inflicted damage, dissruption of tissue
-
Endemic spread
Steady freq. in particular geographic location for a long time
-
Sporadic Spread
Occassional cases at irregular intervals and/or locations
-
Epidemic
Increase in endemic and sporadic greater than expected
-
Pandemic
World wide epidemic
-
Prevelance
Accumulated total of exisiting cases with respect to entire population
-
Incidence
Number of new cases dictated by certain time period
