Investigation and management of three cases of Chlamydia psittaci fever in Zigong City in 2023
Chlamydia psittaci is a zoonotic respiratory infection.To provide a reference basis for psittaciosis-specific pre-vention and control,we conducted a retrospective analysis reviewing the clinical and epidemiological characteristics of three pa-tients.All patients had a history of avian or bird contact,and their clinical symptoms were primarily high fever and pneumonia.Chlamydia psittaci nucleic acid testing was conducted on the patients'close contacts,surrounding occupational populations,and their living environments.No positive findings were observed among the cases'close contacts and surrounding occupational populations,whereas environmental positivity was detected in the feces of the patients'neighbors(25.0％,3/12)and in the ef-fluent(22.2％,2/9)of a wild bird activity area.Positive samples were subjected to ompA gene sequencing,which revealed that the strains in three patients were genetically sequence-identical to that found in pigeon feces.This study enhances under-standing of the epidemic caused by Chlamydia psittaci,elucidates its transmission mechanisms,and provides critical insights for subsequent investigations and management of the disease.
