Anaerobic Spondylodiscitis caused by Parvimonas Micra in a Rheumatoid Arthritis Patient: Case Report and Review of the Literature.

Abstract

We report the rare case of Parvimonas micra bacteraemia and secondary spondylodiscitis probably triggered by tooth injury in a rheumatoid arthritis patient. Anaerobic bacteria associated spondylodiscitis may evade diagnosis due to atypical clinical presentation usually lacking fever, and the difficulties related to microbiological characterisation of the pathogen. Even though anaerobic spinal infections may constitute <3% of the total, clinical suspicion should remain high, especially in the case of positive history for pre-existing oral cavity or gastrointestinal/gynaecological tract infections.
