very red, necrotic nose, mannheimia synergism, fibrinonecrotic membrane

Question 13

pathogenesis of atrophic rhinitis in pigs

Answer 13

bord and pasteurella infection ihibits osteoblasts and increases osteoclasts, loss of nasal conchae causes septal deviation

causes myeloencephalopathy and abortions in mares, can remain latent in trigeminal ganglia

Question 17

horner’s syndrome

Answer 17

miosis and upper eyelid dropping, elevated third eyelid, caused by nerve compression from swelling

Question 18

ethmoid hematoma

Answer 18

common in horses, pedunculated mass from conchae, unilateral nasal bleeding

Question 19

most common canine nasal tumor

Answer 19

adenocarcinoma

Question 20

Answer 20

retroviral induced neoplasia in sheep and goats, less facial deformities

Question 21

most common nasal tumor of cats

Answer 21

nasal lymphoma

Question 22

calf diphtheria

Answer 22

secondary infection of fusobacterium necrophorum, fibrin can block the larynx

Question 23

Oslerus osleri

Answer 23

parasitic tracheobronchitis in young dogs

Question 24

clara cells

Answer 24

unique non-ciliated epithelial cell in the bronchioles that act like stem cells and secrete protective factors

Question 25

type I pneumocytes

Answer 25

flat epithelial cells necessary for gas exchange, replaced by type II temporarily after injury

Question 26

RAO/asthma histo changes

Answer 26

chronic hypersensitivity causes goblet cell metaplasia and sometimes smooth muscle hypertrophy

Question 27

equine exercise induces pulmonary hemorrhage

Answer 27

massive rupture of small alveolar capillaries following exercise, epistaxis

Question 28

emphysema vs bullae

Answer 28

e- septal rupture with crepitus, really looks like streaks of bubbles in lungs b- large air pockets, can lead to pneumothorax

Answer 29

lung collapse

Question 30

suppurative bronchopneumonia

Answer 30

cranioventral dark red, firm lung tissue, often aerogenous route

Question 31

shipping fever

Answer 31

mannheimiosis causes severe fibrinous bronchopnumonia, often fatal, very prevalent in US

Question 31

fibrinous bronchopneumonia

Answer 31

DARK red, firm, cranioventral with fibrillar material on pleura, aerogenous

Question 32

actinobacillus suis (s)/ pleuropneumonia (p)

Answer 32

swine infection that causes an embolic lung pattern, both very deadly, p involves persistent infections

Mycoplasma bovis infection

Answer 33

large areas of pulmonary abscessation

Question 34

indicative of aspriation

Answer 34

necrosuppurative

Question 35

interstitial pneumonia

Answer 35

caudodorsal/diffuse, rubbery with rib impressions and no collapse, direct alveolar damage, caused by toxins and viruses

Question 36

canine distemper virus

Answer 36

lymphoid atrophy, some inclusions and viral syncytia (fused infected cells)

Question 37

bovine pulmonary edema and emphysema

Answer 37

caused by lush grass w/ L-tryptophan, eventually transforms to free radicals in club cells, causes necrosis of type I and bronchiolar cells, fibrin exudate, very bumpy lungs

Question 38

ovine progressive pneumonia/ caprine arthritis and encephalitis

Answer 38

lentiviruses have a long incubation after often being transmitted in the colostrum, very rubbery lungs

Question 39

rhodococcus equi

Answer 39

infects young foals/ immunodeficient, causes small multifocal granulomatous lesions
