− | *Response of the lungs to aspirated foreign material will depend on the nature of the material (e.g. food), the bacterial load and the distribution of the material within the lungs
| |
− | *Mild bronchopneumonia can develop into a severe necrotising pneumonia and in very severe cases can progress to gangrenous pneumonia (below)
| |
− | *In Cattle
| |
− | **Associated with poor husbandry
| |
− | **Regurgitated ruminal content
| |
− | **Cranio-ventral distribution
| |
− | **Respiratory insufficiency secondary to [[:Category:Cardiovascular System - Developmental Pathology|congenital cardiac disease]]
| |
− | *In Horses
| |
− | **Most commonly in right ventral lung lobe (most rostral secondary bronchus leads to right accessory lobe)
| |
− | **Risk factors:
| |
− | ***[[Oesophagus - Anatomy & Physiology|Oesophageal]] obstruction
| |
− | ***Spontaneous reflux (GI obstruction, equine grass sickness)
| |
− | ***[[Respiratory System Clinical Signs - Pathology#Dysphagia|Dysphagia]]
| |
− | ***Iatrogenic
| |
− | ****Nasogastric tube in the wrong place
| |
− | *In Dogs
| |
− | **Most commonly [[Control of Feeding - Anatomy & Physiology#The Vomit Reflex|vomited]]/regurgitated material or contrast medium introduced into airways
| |
− | **In severe acute cases may die from septic shock
| |
− | **In chronic cases -> [[Lungs Inflammatory - Pathology#Bronchopneumonia|bronchopneumonia]]
| |
− | **Common sequel to [[Myasthenia Gravis|myasthenia gravis]], [[Megaoesophagus|megaoesophagus]] or [[Persistent Right Aortic Arch|persistent right aortic arch]]
