* Macroscopically they have patchy consolidation.
* Microscopically exudation and interstitial changes are seen.
* They are best seen with Giemsa stain as inclusions called '''Leventhal -Colle-Lillie bodies''' and can be seen within macrophages in BAL fluid.

* Culture of Chlamydia psittaci is hazardous and should only be carried out in biosafety laboratories.
* It is tedious process and seldom done .


===Serology===
* A fourfold or greater increase in [[antibody]] titers are  against the diagnosis of ''C. psittaci'' in blood samples combined with the probable course of the disease.
