Detection of zoonotic Coxiella burnetii causing chronic Q fever endocarditis in a Chinese geriatric patient by mNGS

mNGS could provide a rapid and accurate assay for clinical diagnosis and play a decisive role in the pathogenetic diagnosis of some infectious diseases. Doxycycline plus hydroxychloroquine remains an effective treatment for chronic Q fever endocarditis. In addition, phylogenetic tree analysis indicates that C. burnetii infection may pose a potential risk to humans working with livestock.
