Development of Disease Flashcards
4 Disease factors
- Volume of exposure
- Virulence
- Concurrent dz/multiple infx
- Drug resistance
6 Host Factors
- Vax
- Immune system
- Nutrition
- Genetics
- Other dz/stress
- Hygiene
5 Development stages of disease
- Exposure
- Infection
- Immunity
- Incubation
- Clinical dz
If a lesion is found in one spot, it is
focal
If a lesion is found in 2 spots, it is
bifocal
If a lesion is found in many spots, it is
multifocal
If a lesion is found everywhere, it is
Diffuse
If a lesion is stuck together, it is
coalescing
Those dz and infections naturally transmitted between man and other vertebrate species
Zoonosis
Kittens and puppies should be dewormed every _ weeks until _ weeks of age, then monthly til _months
2, 8, 6
Fecal exams should be done
1-4x/yr
Heartworm tests should be done on dogs _________
yearly
“viewing death”
necropsy
“viewing self”
autopsy
Legal documents where date and time, owner info, animal info, pre-mortem Dx and Tx, gross findings, tissues pending, and interpretation, Dx, and summary
Necropsy report
If you do this to an animal post mortem, it will complicate cell histopathology
freeze
When examining a fetus post-mortem, you should do these 3 things
- Examine fetal membranes
- Weigh animals
- Measure the crown-rump length
Positioning of a small animal during necropsy
Left lateral, then dorsal
Positioning of ruminants and horses during necropsy
left lateral
Positioning of birds during necropsy
Dorsal
Positioning of fetus during necropsy
right lateral
Procedure of a necropsy (4 steps)
- External exam
- Abdominal cavity
- Thoracic cavity
- Head and musculoskeletal system
Most used fixative for histopathology samples because it prevents autolysis
CARCINOGENIC!!!!!
Formalin
When placing tissue into formalin. the ratio should be
10:1
Formalin to tissue
For large tissue samples, use
50% formalin
