16
Q

consequence of bronchitis

A

non - healing
changes in the lumen
atelectasis
emphysema
pneumonia
amyloidosis - secondary

17
Q

changes in the lumen

A

narrowing
*bronchostenosis
*obturation
*compression
dilation
*bronchiectasia - permanent

18
Q

Bronchiectasia pathogenesis

A

remodelling the wall of the bronchus
elastic elements of the wall disintegrate
CT proliferates instead
cannot resist the pressure or pulling
accumulation of the inflammatory exudate
shrinking of ct

19
Q

forms of Bronchiectasia

A

– Atrophic - wall of the bronchus narrower
– Hypertrophic - thickening of the wall

20
Q

appearance of Bronchiectasia

A

– Cylinder like (br onchiectasia cylindriforme)
– Spindle like (br. fusiforme)
– Sack like (br. sacciforme)

21
Q

BHV 4/Movar infection of cattle

A
  • Aerogenous infection
  • Proliferation in the mucosa
  • Destruction of the mucosa in less ventilated area of lung
22
Q

consequence of Bronchiectasia

A

local changes
abortion
immune suppression
acute interstitial pneumonia
necrotic bronchopneumonia

23
Q

pathology of Bronchiectasia

A

*In the cranial and medial lobes
– Unevenly dilated bronchi
– Filled with muco purulent exudate
– Connective tissue in the bronchus wall
–Atrophy of the parenchyma

*Regional lymph nodes
– Chronic inflammatory reactions

24
Q

infectious bovine rhinotracheitis etiology

A

herpes virus
alphaherpes virus
varicellovirus

25
Q

pathomechanism of infectious bovine rhinotracheitis

A

endemic infection
airways - inflammation – viraemia in lungs and uterus – secondary infection

26
Q

what happens after acute phase in infectious bovine rhinotracheitis

A

latency

27
Q

symptoms of infectious bovine rhinotracheitis

A

fever
resp signs
serous nasal discharge
red nose
abortion

28
Q

secondary infection of infectious bovine rhinotracheitis

A

Pasteurella multocida,
Mannheimia haemolytica : mucopurulent

29
Q

pathology of infectious bovine rhinotracheitis

A

nasal cavity, pharynx, larynx bleeding, inflammation, pseudomembranes
