Lower respiratory tract Part 2 Flashcards
what type of pneumonia induced by PRRS?
Lymphocytic to neutrophilic histiocytic interstitial pneumonia
What are potential extra-pulmonary diseases for prss
lymphadenopathy & multisystemic lymphocytic inflammation (kidney, brain, heart & nasal mucosa) & abortigenic!
What are disease manifestation with porcine circovirus 2?
i. granulomatous interstitial to bronchointerstital pneumonia +/- bronchiolar necrosis
ii. lymphadenitis
iii. lymphoid depletion (causes immunosuppression)
iv. interstitial nephritis
v. myocarditis
vi. meningoencephalitis
vii. vasculitis
viii. porcine dermatopathy & nephropathy
What lesions are induced by PCV2?
porcine multisystemic wasting syndrome, dermatopathy & nephropathy syndrome
Actinobacillus pleuropneumoniae signs?
fever, lethargy, dyspnea, bloody nasal discharge
Typical lesions with Actinobacillus pleuropneumoniae?
fibrinosuppurative- hemorrhagic- necrotizing bronchopneumonia +/- pleuritis
What are the major bacterial (1) and viral agents (3) of the porcine respiratory disease complex.
a. Bacterial: Mycoplasma hyopneumoniae
b. Viral: PRRS, PCV2, Influenza A
typical pulmonary lesion pattern with Mannheimia haemolytica?
acute fibrino-necrotic bronchopneumonia
Pulmonary lesion pattern for Histophilus somni
acute fibrinous bronchopneumonia with pleuritis
Histophilus somni extrapulmonary lesions
thrombotic meningoencephalitis, septicemia with pericarditis, polyarthritis & vasculitis.
Typical pulmonary lesions for mycoplasma bovis with distribution?
caseous to caseonecrotic bronchopneumonia (cranioventral consolidation)
Mycoplasma bovis extrapulmonary lesions
polyarthritis, otitis media, mastitis & conjunctivitis
What is a reportable, foreign animal disease?
Contagious bovine pleuropneumonia
Major bacterial (4) & viral agents (5) of the bovine respiratory disease complex?
a. Bacterial: M.haemolytica, H. Somni, M. bovis, Pasteurella multocida
b. Viral: Bovine herpesvirus, Bovine respiratory syncytial virus, Parainfluenza 3, BVDV & Bovine coronavirus
Typical lesions of Contagious bovine pleuropneumonia & distirbution
marked fibrinous pleuropneumonia ( unilateral & involving caudal lobes)
What technique is required to visualize bovine tuberculosis microscopically?
acid fast stain
Caustive agent of bovine tuberculosis?
Mycobacterium bovis
Small ruminant lentiviral infection manifestation?
encephalomyelitis & arthritis ( concurrent or independent)
-immunosuppression is not a feature unlike feline or primate lentiviruses!
Causative agent of ovine pulmonary adenocarcinoma
Jaagsiekete sheep retrovirus (JSRA)
Virus associated with equine multi-nodular pulmonary fibrosis:
gammaherpesvirus 5
equine multi-nodular pulmonary fibrosis pulmonary lesions:
progressive fibrosing interstitial lung disease causing multiple firm fibrotic lung nodules
Pneumonia pattern for Rhodococcus equi? & distribution
- pyogranulomatous bronchopneumonia (cranioventral distribution, but can affect majority of lung)
Canine distemper virus potential disease manifestations:
i. respiratory sys: bronchointerstitial pneumonia w/ bronchiolar necrosis
ii. ocular: conjunctivitis, keratitis
iii. dental: enamel hypoplasia
iv. CNS: demyelination of white matter, necrotizing meningoencephalitis, old dog encephalitis
v. Skin: hyperkeratotic parakeratosis of footpad
vi. GI: enteritis
vii. Bone: Bone sclerosis
What is the viral strain for canine influenza?
H3N8 influenza A (from horse)
