Pulmonary Infection Detected via Metagenomic Next-Generation Sequencing in a Clonorchiasis Patient: A Case Report.

() is a Gram-negative obligate intracellular bacterium with a global presence across various hosts, including mammals, humans, and ectoparasites. Herein, we present a case of infection in a previously healthy 43-year-old male with a history of and recent corticosteroid use. The identification of was accomplished through metagenomic next-generation sequencing (mNGS) of the patient's bronchoalveolar lavage fluid (BALF). This case represents the first documented pulmonary infection caused by in China, confirmed by mNGS analysis of bronchoalveolar lavage fluid (BALF) and reported from Shenzhen, China.
