Spondylodiscitis caused by Bordetella holmesii, a misrecognized pathogen emerging in invasive infections

Abstract

We report a case of spondylodiscitis caused by Bordetella holmesii, an emergent pathogen. This small Gram-negative rod was first known as a cause of invasive infections on asplenic patients. This case describes a spondylodiscitis due to this bacterium in an immunocompetent patient. This article underlines the interest of prolonged incubation for specimens in case of spondylodiscitis and shows us the contributions of mass spectrometry for easy and rapid identification of such bacterium. Keywords: Spondylodiscitis, Bordetella holmesii, MALDI-TOF
