Abstract
Legionella Ltongbeachae is ubiquitously found in both aqueous environments and moist soils worldwide, sometimes causing severe pneumonia. Legionella longbeachae pneumonia can cause severe lower respiratory tract illness leading to fatal outcomes. But Legionella longbeachae is rarely reported in China. Here we present a case of Legionella longbeachae pneumonia detected by NGS in a 73-year-old woman, who was a farmer working in a vegetable greenhouse and was diagnosed as diabetes 2 before. The patient experienced severe chills and fever when she was transfer to our hospital. Anyway, the symptoms resolved after targeted anti-infection treatment and low-dose hormone therapies plus insulin treatment. Besides that, we reviewed the Legionella longbeachae pneumonia in China and type 2 diabetes is a possible risk factor that could facilitate Legionnaires' disease. The case reported herein may serve as a warning to public health and a cue for the successful management of diseases associated with Legionella longbeachae.
