Pyogenic Spondylitis and Diskitis Caused by Helicobacter cinaedi in an Immunocompetent Adult Patient

We herein describe the first reported case of pyogenic spondylitis and diskitis caused by Helicobacter cinaedi. The results of magnetic resonance imaging and the histology of biopsied tissue were suggestive of acute infection at the lumbar spine. The pathogen was obtained by a blood culture examination and identified by 16S rRNA analysis. Eight weeks of antibiotics therapy resulted in a good clinical course. H. cinaedi infections have been increasingly reported in recent years, but the pathogen's epidemiological and pathological characteristics are still unclear. One of the difficulties in understanding the pathogenesis of H. cinaedi has been the challenges in cultivating the pathogen. Novel strategies for the diagnosis of H. cinaedi must be developed.
