Overview

The pathologic process starts with the inoculation of tracheobranchial epithelium with invading organism which leads to inflammation, thickening and increased mucos production.

Pathophysiology

  • The causative agent, either viruses or bacteria transmitted via airways to the large and medium size airways tract[1].
  • Following transmission, the bug starts to inoculate the tracheobronchial epithelium[1].
  • This process leads to inflammation, thickening, and increased mucus production in the airways compared to normal bronchi as shown below[1].
  • 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].
