Background: Chlamydia psittaci can bring about serious clinical manifestations, including a typical Pneumonia, Chills, sore throat, and headache and so on. It is possible that Chlamydia psittaci pneumonia was confused with COVID-19 during the COVID-19 pandemic. Methods: Metagenomic Next-Generation Sequencing (MNGS) was performed and thirty-two patients who were diagnosed with Chlamydia parrot’s pneumonia were collected. The patients, clinical characteristics and key points of diagnosis and treatment of the disease were summarized. Results: All of patients showed atypical pneumonia. Frequent symptoms included headache (17/32), fever (2/32), myalgia (3/32), cough and expectoration (26/32). Laboratory data showed elevated WBC (4/32), percentage of neutrophils (30/32), CRP (32/32), PCT (15/26), BUN (10/32), CRE (4/32), ALT (21/32), AST (25/32), TB (4/32), DB (14/32). All patients experienced complete recoveries after doxycycline or doxycycline-based therapy. MNGS provided the results of the exact pathogen, while conventional etiological tests did not. Conclusion: Facing the covid-19 pandemic, atypical pneumonia except for COVID-19 should also be considered. MNGS technology for the diagnosis of Chlamydia parrots pneumonia is of great significance, especially suitable for people with unknown pulmonary infection pathogen, timely to make the appropriate antimicrobial therapy effective.
