A
  • interstitial pneumonia similar to OPP
30
Q

enzootic nasal tumor virus

-> ?

A
  • sheep ENTV-1
  • goat ENTV-2
  • Nasal adenoma -> carcinoma rarely metastasizes
31
Q

sheep: retrovirus-induced ovine pulmonary adenocarcinoma (OPA) see what grossly

A
  • areas neoplasia replace lung parenchyma w/ firm white fibrotic neoplastic lesions
32
Q

jaagsiekte sheep retrovirus virus causes what

A

neoplastic change inland keeps growing until large portion of lung affected (looks like opa)

33
Q

granulomatous interstitial pneumonia occurs how

A

organisms or particles -> resist intracellular killing by phagocytic cells -> persist and cause chronic granulomatous inflammation response

34
Q

granulomatous interstitial pneumonia include

A
  • bovine pulmonary tuberculosis
  • granulomatous/ pyogranulomatous pneumonia horse
  • FIP
35
Q

bovine pulmonary tuberculosis is caused by what

A
  • mycobacterium bovis

- zoonotic

36
Q

mycobacterium bovis bovine pulmonary tuberculosis signs

A
  • lung granulomas (tubercles); multifocal variably sized accesses in cd lung goes
  • lymph node involvement (accesses in ln)
  • +/- mineralization
37
Q

what causes caseous accesses in lungs (pathogens)

A
  • mycobacterium bovis

- trueparella pyogeneis

38
Q

mycobacterium bovis vs trueparella staining

A
  • mycobacterium are acid fast trueparella is not
39
Q

mycobacterium tuberculosis affects who

A
  • human beings (only reservoir host)
  • dogs and cats are susceptible
    dogs= respiratory
    cats = enteric
40
Q

granulomatous/ pyogranulomatous pneumonia cause horse

A

rhodococcus equi
- may have multiple small granulomatous lesions not just one larger lesion

  • in foal 1-6 months this = primary differential, can look like trueparella and mycobacterium but in foal look at this first*
41
Q

feline infectious peritonitis -> what kind of lesions

A
  • granulomatous lesions throughout lungs

- can have lesions on other organs as well

42
Q

interstitial pneumonia primary mycotic agents multifocal and granulomatous

Q

canine blastomycoides affects who

A

dogs and humans rare in other domestic aniamls

45
Q

canine blastomycosis see what

A
  • pyogranulomatous interstitial pneumonia w/ diffuse patterns through lungs
  • broad based budding coccidian mycosis= broad-based budding yeast
46
Q

blastomyces dermatitis -> what kind of mycosis; form and infections phase

A

systemic mycosis

  • dimorphic fungus
  • gross as yeast phase = non- infectious
  • hematogenous and lymphatic dissemination

cutaneous form
- penetrating wound

47

- horse

51
Q

pneumocystis carinii what type of infection

A

opportunistic fungal infection

52
Q

  • metacestode lungs of intermediate host

lung- migrating parasits

  • larva migrans
  • flukes
53
Q

embolic pneumonia spread how

A

hematogenous spread from elsewhere

  • fungal
  • bacterial
54
Q

emobolic pneumonia presentation

A
  • multifocal- random- all lobes
55
Q

fungal causes embolic pneumonia

A

aspergillis spp.

56
Q

bacterial causes embolic pneumonia

A
  • trueperella pyogenes

- fusobacterium necrophorum

57
Q

pulmonary aspergillosis -> what in horse

A
