Lecture 28 Flashcards
What is eqiune parainfluenzia
- Mild and self-limiting bronchointerstital pneumonia
- Unless complicated by secondary bacterial infection
What is equien viral rhinopneumonitis
- Mild and self-limiting bronchointerstital pneumonia
What is equine henipavirus
Hendra
What can be seen with equine henipavirus
- Severe pulmonary oedema
- Multinucleated syncytical cells of endothelial cells
- Vasculitis
- respiratory, neurological and gastrointestinal signs
What does equine viral arteritis
- Oedema, haemorrhage and marked hydrothroax
- Vasculitis
- Interstitial pneumonia with hyperplasia of Type II pneumonocytes
What does African horse sickness cause
- Severe respiratory distress with extensive pulmonary oedema
What does Rhodococcus equi cause
- Suppurative to pyogranulomatous pneumonia
- Ulcerative enteritis
Pygranulomatous Pneumonia (Rhodococcus equi)
What does bovine enzoontic pneumonia cuase
- Begins with viral infection
- Mycoplasmas
- Followed by bacterial secondary infection
- Mycoplasmas and viruses cause bronchiolitis, bronchiolar and alveolar necorsis
- Secondary supurative bronchopneumonia
Necrotising Bronchiolitis - Bovine respiratory syncytial virus
What is pneumonic manheimiosis
- Severe respiratory distress
- Often after transport, often in feedlots
- Need stressors to establish
- Severe fibrinous bronchopneumonia of cranioventral lung
- Fibrin on pleura and excess thoracic fluid
- A necrotising proces sleads to formation of abscesses as well as adhesion to the thoracic wall in aniamls that do not die
Pneumonic Mannheimiosis - Fibrinous Bronchopneumonia
Pneumonic Mannheimiosis
What does Haemorrhagic septicaemia cause
- Oedematous and haemorrhagic pneumonia
- Haemorrhages and bacteria in other parts of the body
What does respiratory histophilosis cause
- Suppurative and fibrinous bronchopneumonia
- Part of the Histophilus somni complex
What causes contagious bovine pleuropneumonia
- Mycoplasma mycoides subp mycoides
What is seen with contagious bovine pleuropneumonia
- Severe fibrinous bronchopneumonia
- Pronounced interlobular oedema and lymphatic thrombosis
- Development of large necrotic foci surrounded by fibrous tissue
What is seen with bovine tuberculosis
- Granulomatous pneumonia
Where do Verminous pneumonia (Dictyocaulus viviparus) lung worm live and whay do they cause
- Bronchi
- Bronchitis
- Pulmonary oedema
- Atelectasis
- Interstitial emphysema
- Appears as large, dark or grey depressed areas
Verminous pneumonia (Dictyocaulus viviparus) lung worm
Verminous pneumonia (Dictyocaulus viviparus) lung worm
Verminous pneumonia (Dictyocaulus viviparus) lung worm
What is Hydatidosis
- Cystic intermediate stage of the dog tapeworm Echnococcus granulosus
Hydatidosis
What causes Mannheimia haemolytica in sheep
- Facilitated by stressors such as cold, weather, handling, drenching, viral infection
Fibrinous Bronchopneumonia - Ovine pneumonic Mannheimiosis
What does chronic Enxootic Pneumonia cause
Normally non-fatal disease of sheep
- Weightloss
- Mixture of infectious agents
- Ctanioventral bronchointerstitial pneumonia with Type II pneumonocyte hyperplasia
Suppurative Bronchopneumonia
What is contagious caprine Pleuropneumonia
- Severe fibrinous bronchopneumonia and pluritis
- Disease similar to contagious bovine pleuropneumonia
Explain what Dictyocaulis filaria causes
- Lesions mostly in dorsal lungs with areas of atelectasis
- Esonophilic bronchitis and bronchiolitis
- Peribronchial lymphoid hyperplasia
- Type II pneumonocyte hyperplasia
- Interstitial thickening of alveolar walls
What does Muellerius capillaris called in sheep
Nodular lung worm
Where are the lesions of Muellerius capillaris located
Numerous in the dorsal caudal lobes
- Sofr, haemorrhagic nodules in early stage
- Become grey-green harder lesions in chronic ctages
- Focal, eosinophilic granulomatous lesions in the subpleural alveolai
