*Caused by a [[Paramyxoviridae#Canine Distemper Virus (CDV)|morbillivirus]]

*[[Nasal Cavity Inflammatory - Pathology#Infectious causes of rhinitis|Rhinitis]]

*Although many organs can be affected by CDV, a relatively constant feature is the respiratory signs which occur in varying severity
 +
*A syndrome of catharral oculonasal discharge, [[Nasopharynx Inflammatory - Pathology#Infectious causes of pharyngitis|pharyngitis]] and [[Bronchi and Bronchioles Inflammatory - Pathology#Infectious causes of bronchitis or bronchiolitis|bronchitis]] is relatively common in the initial stages
 +
*Since one of the primary sites of action of this virus is lymphoid tissue, the resultant immunosuppression -> predisposition to secondary bacterial infection
 +
*May cause [[Lungs Inflammatory - Pathology#Interstitial pneumonia|interstitial pneumonia]] where [[Degenerations and Infiltrations - Pathology#Cellular Inclusions|inclusions]] are found within alveolar macrophages

*Gross pathology:

**Oedematous lungs, diffuse interstitial pneumonia

*Micro pathology:

**Necrosis of pneumocytes, necrotising bronchiolitis, alveolar oedema, thickening of alveolar walls and type II pneumocyte hyperplasia
