Study Notes
Nasal Cavity Conditions
- Epistaxis: Nosebleeds caused by trauma, foreign bodies, neoplasms, or specific conditions in animals like squamous cell tumors in cats and ruptured pulmonary vessels in cattle.
- Hemoptysis: Blood coughed up or present in the mouth, indicating respiratory issues.
- Rhinitis: Inflammation of the nasal cavity presenting with unilateral or bilateral nasal discharge, classified as acute, subacute, or chronic.
- Sequels of Rhinitis: May lead to lymphadenitis or empyema (pus accumulation in sinuses).
Diseases of the Nasal Cavity and Sinuses in Cattle
- Infectious Bovine Rhinotracheitis (IBR): Acute viral disease caused by Bovine herpesvirus 1, featuring respiratory and genital forms, and potential for abortion.
- Gross Symptoms of IBR: Hyperemia of nares, erosion and ulceration in the upper respiratory tract, and mucosal membranes may have a yellowish pseudomembrane.
- Malignant Catarrhal Fever (MCF): Multi-systemic disease caused by Ovine herpesvirus-2, leading to corneal opacity, gastrointestinal erosions, and respiratory complications.
Diseases in Horses
- Strangles: Bacterial disease caused by Streptococcus equi characterized by purulent rhinitis and lymphadenitis with abscesses, leading to potential complications like purpura hemorrhagica and laryngeal hemiplegia.
- Glanders: Highly contagious granulomatous disease caused by Burkholderia mallei, presenting as nasal, cutaneous, and pulmonary forms with distinct nodules and crusting.
Other Species Conditions
- Nasal Bots (Myiasis): Caused by Oestrus ovis, where larvae invade the nasal cavity following ingestion of eggs.
- Bacterial Infections in Sheep: Involvement of Pasteurella multocida and Mannheimia haemolytica alongside foreign body rhinitis is common.
Canine Respiratory Viruses
- Significant pathogens include:
- Canine Distemper Virus: Causes systemic illness affecting respiratory signs.
- Canine Adenovirus (CAV-2): Associated with kennel cough.
- Canine Parainfluenza virus (CPI-1): Another contributor to kennel cough.
