25
ovine progressive pneumonia see what
- arthritis/ synovial hyperplasia - mastitis - lymphadenopathy - resp dx w/ diffuse lung involvement
26
ovine progressive pneumonia spread
- widespread infection/ rare clinical dx
27
ovine progressive pneumonia see clinical dx in who
- older animals
28
caprine arthritis and encephalitis cause
lentivirus
29
caprine arthritis and encephalitis see what
- interstitial pneumonia similar to OPP
30
enzootic nasal tumor virus | -> ?
- sheep ENTV-1 - goat ENTV-2 - Nasal adenoma -> carcinoma *rarely metastasizes*
31
sheep: retrovirus-induced ovine pulmonary adenocarcinoma (OPA) see what grossly
- areas neoplasia replace lung parenchyma w/ firm white fibrotic neoplastic lesions
32
jaagsiekte sheep retrovirus virus causes what
neoplastic change inland keeps growing until large portion of lung affected (looks like opa)
33
granulomatous interstitial pneumonia occurs how
organisms or particles -> resist intracellular killing by phagocytic cells -> persist and cause chronic granulomatous inflammation response
34
granulomatous interstitial pneumonia include
- bovine pulmonary tuberculosis - granulomatous/ pyogranulomatous pneumonia horse - FIP
35
bovine pulmonary tuberculosis is caused by what
- mycobacterium bovis | - zoonotic
36
mycobacterium bovis bovine pulmonary tuberculosis signs
- lung granulomas (tubercles); multifocal variably sized accesses in cd lung goes - lymph node involvement (accesses in ln) - +/- mineralization
37
what causes caseous accesses in lungs (pathogens)
- mycobacterium bovis | - trueparella pyogeneis
38
mycobacterium bovis vs trueparella staining
- mycobacterium are acid fast trueparella is not
39
mycobacterium tuberculosis affects who
- human beings (only reservoir host) - dogs and cats are susceptible dogs= respiratory cats = enteric
40
granulomatous/ pyogranulomatous pneumonia cause horse
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
feline infectious peritonitis -> what kind of lesions
- granulomatous lesions throughout lungs | - can have lesions on other organs as well
42
interstitial pneumonia primary mycotic agents multifocal and granulomatous
- blastomyces dermatidis - nocardia asteroides/ nova - cryptococcus neoformans - coccidiodes immitis - pneumocystis carnii
43
canine blastomycoidis caused by what
blastomyces dermatitis
44
canine blastomycoides affects who
dogs and humans rare in other domestic aniamls
45
canine blastomycosis see what
- pyogranulomatous interstitial pneumonia w/ diffuse patterns through lungs - broad based budding coccidian mycosis= broad-based budding yeast
46
blastomyces dermatitis -> what kind of mycosis; form and infections phase
systemic mycosis - dimorphic fungus - gross as yeast phase = non- infectious - hematogenous and lymphatic dissemination cutaneous form - penetrating wound
47
pulmonary coccidiomycosis affects who
- camelids > horses
48
pulmonary coccidiomycosis caustitive agent
coccidiodes immitus | ZOONOTIC
49
pulmonary coccidiomycosis see what dx
pyogranulomatous interstitial pneumonia
50
pneumocystis carinii seen in who
- pig | - horse
51
pneumocystis carinii what type of infection
opportunistic fungal infection
52
interstitial pneumonia parasitic causes
lung resident parasits - nematodes adult/ larvae in airways/ alveoli - metacestode lungs of intermediate host lung- migrating parasits - larva migrans - flukes
53
embolic pneumonia spread how
hematogenous spread from elsewhere - fungal - bacterial
54
emobolic pneumonia presentation
- multifocal- random- all lobes
55
fungal causes embolic pneumonia
aspergillis spp.
56
bacterial causes embolic pneumonia
- trueperella pyogenes | - fusobacterium necrophorum
57
pulmonary aspergillosis -> what in horse
- embolic fungal pneumonia horse | - enteritis/ colitis/ typhilitis = open door for fungus to enter lung
58
salmonella enterocolitis horse -> what
embolic fungal pneumonia horse - disruption of intestinal barrier - hematogenous spread - localization to other organs - liver/ lungs
59
embolic fungal pneumonia horse differentials
- pulmonary aspergillosis | - salmonella enterocolitis
60
embolic fungal pneumonia horse signs
- necrosuppurative inflam - mass of fungal hyphae - vasculitis/ thrombosis
61
embolic pneumonia cattle causes
- pulmonary septic embolism- hematogenous
62
aspiration pneumonia lesions
- focal necrohemorrhagic pneumonia (one lobe) - foreign body aspriation - necrosis - hemorrhage - inflammation
