Diagnosis involves [[microbiological culture]]s from respiratory secretions of patients or [[serology|serologically]] with a fourfold or greater increase in [[antibody]] titers against ''C. psittaci'' in blood samples combined with the probable course of the disease. Typical inclusions called Leventhal -Colle-Lillie bodies can be seen within macrophages in BAL fluid. Culture of Chlamydia psittaci is hazardous and should only be carried out in biosafety laboratories. | Diagnosis involves [[microbiological culture]]s from respiratory secretions of patients or [[serology|serologically]] with a fourfold or greater increase in [[antibody]] titers against ''C. psittaci'' in blood samples combined with the probable course of the disease.

Overview
Exposure history is paramout to diagnosis. Bloodwork shows leukopenia, thrombocytopenia and moderately elevated liver enzymes.
Laboratory Findings
Electrolyte and Biomarker Studies
- Leukocytosis
- Rise in ESR
- Rise in CRP
- Liver enzymes elevated
- Hyponatremia may be noticed
- Rise in blood urea levels
- Urinalysis may show proteinuria
Chest X Ray
- Lobar consolidation may be seen
- Infiltrates may be evidenced
CT Scan
- On high resolution CT , infiltrates may be nodular and surrounded by ground glass opacity.[1]
Diagnosis involves microbiological cultures from respiratory secretions of patients or serologically with a fourfold or greater increase in antibody titers against C. psittaci in blood samples combined with the probable course of the disease. Typical inclusions called Leventhal -Colle-Lillie bodies can be seen within macrophages in BAL fluid. Culture of Chlamydia psittaci is hazardous and should only be carried out in biosafety laboratories.
