Destructive osteomyelitis involving Parvimonas micra and Campylobacter rectus

We present a rare case of destructive osteomyelitis of the sternum caused by Parvimonas micra and Campylobacter rectus A previously healthy female patient in her 40s presented to the emergency department due to a spontaneous rupture of an abscess located to the chest wall. Imaging confirmed abscess formation with osteomyelitis of the sternum. Emergent surgical debridement was performed, blood and bone cultures were taken and the patient received antibiotic treatment. Cultures of the bone and deep tissue revealed infection with Parvimonas micra and Campylobacter rectus, both being members of the oral flora and associated with chronic periodontitis. Receiving targeted antibiotic treatment, our patient made a quick recovery. After treatment of the osteomyelitis, our patient was referred to the dentist where chronic periodontitis could be confirmed. Invasive infections with Parvimonas micra and Campylobacter rectus are rare. Investigation of a dental origin is crucial to prevent recurrent infections.
