Rothia aeria mitral valve endocarditis complicated by multiple mycotic aneurysms: laboratory identification expedited using MALDI-TOF MS.

ABSTRACT

Rothia aeria has only rarely been described as a human pathogen. We describe a case of Rothia aeria causing mitral valve endocarditis and multiple mycotic aneurysms, including cerebral mycotic aneurysms. In the case described, early identification of Rothia aeria was achieved using matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS).
