16
Q

When should a room have negative air pressure? Positive?

A

Negative: ABSL2/3 pathogens or infectious disease (trying to contain to room)
Positive: Immunocompromised rodents, surgical suites (keep pathogens outside)

17
Q

What animal facility practices would maximize disease prevention?

A

Moving in room order from cleanest to dirtiest
Sanitation
PPE
IVCs, Animal Transfer stations
Treated food and water
Quarantine

18
Q

Food for lab animals in research should be ___ or ___, and water should be _____ or _____

A

Food: Irradiated; autoclaved
Water: Hyperchlorinated; acidified

19
Q

Rodent health monitoring program should be done how often?

A

Quarterly

20
Q

What is the rodent health monitoring program testing for?

A

Rodent specific bacteria, viruses, and parasites that cause clinical disease or affect research

21
Q

What are the two surveillance methods for lab animals?

A

Dirty Bedding Sentinel
Environmental Testing

22
Q

What is the Dirty Bedding Sentinel method of surveillance?

A

-Immune competent mice exposed weekly to dirty bedding of research mice
-Quarterly mice are euthanized, necropsied, and tested for disease by serology

23
Q

What is the Environmental testing method of surveillance?

A

Mouse IVC rack, sample exhaust air duct for disease
Swab exhaust plenums
PCR based

24
Q

Pros/Cons of dirty bedding sentinel method?

A

Pros: Direct test, necropsy, daily surveillance of health
Cons: Animal use, some agents not transmitted by soiled bedding

25
Q

Pros/Cons of environmental testing method?

A

Pros: Reduced animal use, more sensitive for certain pathogens
Cons: DNA detection- can detect dead DNA, so is that pathogen actually active?

26
Q

Lab animal industry is moving towards which method?

A

Environmental testing method

27
Q

What is the first step if you detect a rodent pathogen during quarterly testing?

A

Re-Test!
Use alternative or complementary methods

28
Q

After retesting to confirm a pathogen is actually present, what is your next step?

A

Containment

29
Q

What might a containment plan include?

A

Stop movement of animals, people, and supplies
Limit access to room
Change facility practices
Additional/more frequent testing of animals
Stop breeding

30
Q

What is the final step for biosecurity in lab animal settings?

A

Eradicate

31
Q

Methods of eradication?

A

Depopulate
Disinfect
Repopulate

32
Q

Why is eradication not always feasible?

A

Valuable mouse lines are not always readily available to replace depopulated lines

33
Q

Other options for eradication when depopulation is unavailable?

A

Test and cull
Treat the infection
Rederivation of lines

34
Q

What are some ways to “rederivate” lines of valuable mice when depopulation is not an option?

A

Cross-foster
Embryo transfer
C-section

35
Q

When is an outbreak considered over?

A

Two consecutive negative screens of 100% of cages

36
Q

What are the four basic components of biosecurity?

A

Prevent, Identify, Contain, Eradicate
