Overview
The pathologic process starts with the inoculation of tracheobranchial epithelium with invading organism, which leads to inflammation, thickening and increased mucus production.
Pathophysiology
Pathogenesis
- The causative agent is transmitted through the large and medium size airway tracts.[1]
- Following transmission, the agent inoculates the tracheobronchial epithelium.
- This process leads to inflammation, thickening, and increased mucus production in the airways compared to normal bronchi as shown below:
-
Normal Bronchi
-
Inflamed Bronchi
Microscopy
- On microscopic analysis, epithelial-cell desquamation and denuding of the airway to the level of the basement membrane, in association with the presence of a lymphocytic cellular infiltrate, have been demonstrated.[2]
