Resp path II Flashcards
contavious bovine pleuropneumonia cause
mycoplasma mycoides spp. mycoides (small colony type)
pleuropneumonia gross histo
- unilateral, cd lung lobe
- marbled apperance
- fibrinous pleuritis/ adhesions
- pleural effusion
differential diagnosis bovine pleuropneumonia
- mannheimia haemolytica
- mycoplasma mycoides spp. mycoides
contagious bovine pleuropneumonia sequestrum
- necrosis secondary to loss of vascular supply
contagious caprine pleuropneumonia cause
- mycoplasma capricolum spp. capripneumoniae
mycoplasma capricolum spp. capripneumoniae contagious caprine pleuropneumonia -> ?
- high mortality
- fibrinous pleuropneumonia
- multifocal necrosis
interstitial pneumonia spread type/ general cause
- aerogenous or hematogenous spread
- most often viral cause
causes porcine interstitial pneumonia
viral - swine influenze - PRRSV - PCV-2 - PRCV - Pseudorabies bacterial (sepsis) - Salmonella choleraseuis - Haemophilus parasuis
swine influenza virus -> clinical presentation and dx
dx - porcine interstitial pneumonia clinical signs -high morbidity - resp signs
swine influenza what type virus/ swine receptos
- segmnted ss RNA
- pig has receptors for human and avian strains
- pt of porcine resp dx complex
porcine interstitial pneumonia histo/ necropsy
- diffuse pattern in lungs
- edema
- airway epithelium damage
necrosis of swine airway differntials
- porcine interstitial pneumonia
- bovine herpes virus 1
porcine reproductive and respiratory syndrome virus (PRRSV) -> ?
- porcine interstitial pneumonia
- target or damage PAM/PIM
- > secondary bacterial bronchopneumonia and sepsis
porcine circovirus type 2 (PCV-2) -> what concurrent with what
porcine respiratory and reproductive syndrome virus
histo of pcv-2 vs porcine respiratory and reproductive syndrome virus
circoviridae see granulomatous inflam
pcv-2 see what
- porcine interstitial pneumonia
- granulomatous infla
- icterus
- enlarged lymph nodes
nipha virus pig can ->
- interstitial pneumonia
- resp and cns dx
- ZOONOTIC
nipha virus genus and fam
- genus= henipavirus
- fam= paramyxoviridae
hendra virus equine genus and fam
- genus= henipavirus
- fam= paramyxoviridae
- ZOONOTIC*
Equine hendra virus -> ?
- interstitial pneumonia
- see massive pulmonary edema
small ruminant lentiviruses include
- ovine progressive pneumonia (OPP)
- caprine arthritis and encephalitis (CAE)
lentiviruses features of dx type
- non-oncogenic/ non-immunosuppressive
- main targets = monocytes, macrophages, dendritic cells
- > chronic inflam
small ruminant lentiviruses pathogeneisis
- acute dx
- chronic dx = slow progressive multi-organ lymphoproliferative fatal dx
- see interstitial fibrosis
ovine progressive pneumonia caused by what
lentivirus
