Q

Applied research

A

directed toward
specific objectives such as the development of new drugs,
therapy, and surgical procedures. Applied research involves
using existing knowledge (much of which is obtained through
basic research) to a specific biomedical problem.

Q

The three R’s

A

-reduction is to use the absolute lowest number of
animals that will achieve the desired results
-refinement is achieved when the most skilled
investigator uses procedures that cause the least discomfort
to the animal to achieve a result that’s of maximum benefit
to humankind.
-Replacement refers to research that uses lower forms of life,
computer models, or other artificial means whenever possible.

Q

animal rights groups

A

generally believe that animals
have the same rights as human beings. This belief extends to
the right to not be killed, eaten, used for sport or research,
kept as pets, or abused in any way to all animals. Individuals
in this category won’t consider euthanasia of an animal even
when the animal is suffering. They believe that animal
research is a violation of the animals’ rights and should
never be conducted.

Q

animal liberation groups

A

individuals
and organizations in the animal liberation category believe
that all life is equal and will commit illegal acts, such as
breaking into research facilities to “free” the animals. These
acts may harm people and, in fact, often bring harm to the
animals that aren’t accustomed to “life in the wild.”

26
barrier | facility
supplies are sterilized before being brought into animal areas, and supplies and personnel usually enter the animal areas through special air locks
27
containment facility
a type of barrier facility in which all materials leaving the facility are sterilized before being discarded. Specialized filter systems are also used to treat the air that flows into and out of the facility.
28

46
Whitten effect
occurs when a large group of female mice housed together | without the presence of males enter and remain in anestrus..when male comes, all females enter estrus w/i 3 days
47

occurs when a female mouse bred within the previous four days is exposed to a new male; the existing pregnancy will be aborted, and the female will return to estrus.
48
barber mouse
Most dominant mouse, often removes hair & whiskers from the faces and sometimes bodies of the other mice
49
Tyzzer’s disease
caused by the bacterium Clostridium piliforme (also called Bacillus piliformis). It’s transmitted by the fecal-oral route. Stress from poor sanitation and overcrowding predisposes animals to this disease.

4 Breeding systems
1-Timed Mating 2-Paired Mating 3-Harem Mating 4-Free-Range Mating
78
TImed Mating
menstrual cycle is monitored, and the female is placed in the male’s cage at or just before the estimated time of ovulation. The result is a known gestational age—an important fact for many intrauterine or postpartum studies
79
Paired Mating
Animals are housed in pairs. The female is | observed for pregnancy by rectal exploration or ultrasound.
80
Harem Mating
One male is housed with a group of | females, either temporarily or permanently.
81
Free-Range Mating
A mixed-sex group lives together within an enclosure, corral, or on an island. Harem and free-ranging systems are most often used in production colonies.
