Journal Title: Shanghai Journal of Preventive Medicine - Year 2023, Vol 35, Issue 6
Abstract
ObjectiveTo identify causal factors of a case of severe Chlamydia psittaci pneumonia in Yangpu District and provide a scientific basis for effective prevention and control.MethodsBasic information and epidemiological data of the patient were collected through telephone interviews and field epidemiological surveys. Specimens from the patientï¼ close contacts and the environment were collected for pathogen detection. Metagenomics next-generation sequencing ï¼mNGSï¼ was used to identify unknown pathogens.ResultsA 65-year-old male patient with a history of hypertension and diabetes was admitted to the hospital with symptoms of fatigueï¼ poor appetite for a weekï¼ fever and cough for four days. A chest computer tomography ï¼CTï¼ scan showed scattered inflammation in the left lung with infiltration of multiple lobes. Blood gas analysis showed type I respiratory failure. The results of mNGS on the bronchoalveolar lavage fluid of the patient indicated that he was infected with Chlamydia psittaci. Epidemiological investigation showed a clear history of avian exposureï¼ with an incubation period of 30 days.ConclusionThis serious pneumonia is a zoonotic disease caused by Chlamydia psittaci. A clear history of avian exposure and the use of mNGS technology can help in the timely diagnosis of this disease.
