SYSTEMIC PATHO Flashcards
A bleeding from nasal passage due to trauma, neoplasm and ulcerative lesions as a result of infection.
Epistaxis
Blood comes from mouth, saliva or sputum
Hemoptysis
Inflammation of the nasal mucosa, may be caused by infections or allergies
Rhinitis
This is present in certain infectious diseases such as strangles, influenza and glanders of horses, and distemper in dog.
Acute Rhinitis
Types of Exudate
- Serous
- Catarrhal
- Fibrinous
- Purulent
- Granulomatous
Increased secretion of submucosal glands
Serous
Goblet cell hyperplasia and excessive production mucus.
Catarrhal
Altered vascular permeability and exudation (escape) of fibrin.
Fibinous
Chemotaxis for polymorphonuclear leukocytes/pus.
Purulent
Granuloma/fibrosis/polyps
Granulomatous
An equine disease characterized by purulent (suppurative) rhinitis and regional lymphadenitis with formation of abscesses.
Strangles (Streptococcus equi)
A commonly involved in feline rhinitis-sinusitis
Feline Rhinotracheitis (FHV-1)
Inflammation of sinuses
Sinusitis
Inflammation of the larynx
Laryngitis
Also called “Calf Diphtheria”, is common in feedlots, predominantly in calves, usually >3 months old.
Necrotic laryngitis
Means leather, due to the type of exudate that forms.
Diphtheria
Inflammation of trachea
Tracheitis
Other Disease Involved larynx and trachea
- Infectious bovine rhinotracheitis (IBR)
- Calf Diphtheria fusiformis necrophorus.
- Feline viral rhinotracheitis
Inflammation of the bronchi, characterized by catarrhal, suppurative, fibrinous or hemorrhagic exudate.
Bronchitis
