Disease & Sanitation Flashcards
Definition:
Infectious disease
Is one caused by the presence of a foreign living organism, which creates a disturbance leading to the development of symptoms. Easily spreadable.
Definition:
Disease
A condition that results from any structural defect or functional impairment of the animal body
Sanitation
The promotion of hygiene and prevention of disease by maintenance of sanitary conditions
Definition:
Livestock
Farm animals kept or raised to produce food or fiber for use and profit
Causes of disease (intrinsic) 7
Genus, species Breed Genetic Age Sex Endocrine Neoplasms
Causes of diseases (extrinsic)
Living agents: micro-organisms (bacteria, viruses, fungi, protozoa)
Non-living agents: trauma temperature, poisons, good deficiencies
Definition:
Contagious disease
May be transmitted from one individual to another by direct or indirect contact.
All contagious diseases are infectious, but not all infectious diseases are contagious.
Common ways infections are contracted by new host
- Direct or immediate contact with a diseases individual ( licking, sexual)
- Contact through fomites (inanimate objects)
- contact with disease carriers ( not showing symptoms)
- infection from soil
- infection from good & water
- airborne infections
- blood sucking Arthropoda
- organisms naturally carried
Definition:
Pathogenic
Easily spreadable
Rule of thumb with micro-organisms
Treat all micro-organisms as if they are a severe threat to the health of the animal
Three ways to microbial control
Sanitation
Sterilization
Disinfection
Definition:
Sanitation
Sanitizers do not destroy or eliminate all micro-organisms, but reduce the number of microbial contamination to a level at which they no longer pose a disease threat to their host.
Definition:
Sterilization
The destruction of all infective and reproductive forms of all micro- organisms.
Definition:
Disinfection
The destruction of all growing forms of microorganisms, but not necessarily the spore forms of disease producing micro-organisms.
Choosing a disinfectant
- Type of surface
- cleanliness of surface
- type of of organisms being treated
- durability of equipment/surface
- time limitations on treatment duration
- residual activity requirements
