Rothia species are pleomorphic gram-positive bacteria that belong to the Micrococcaceae family [1]. The Rothia genus presently comprises 6 named species, 2 of which are deemed clinically relevant: Rothia dentocariosa and Rothia mucilaginosa [2-6]. Another member of the genus, Rothia aeria, a taxon group provisionally named R. dentocariosa genomovar II, is a rare cause of human infections [2, 7] To date, only 6 cases of human infection caused by R. aeria have been reported, including bacteremia [8], neck abscesses [9], respiratory tract infection [10, 11], septic arthritis [12], and infective endocarditis [13]. Although Rothia species have rarely been reported as a causative pathogen of infective endocarditis, no case has been reported in Korea. Moreover, the risk factors for invasive infection by R. aeria are not well defined because of its rarity and the difficulty of correct species identification. Here, we report a case of infective endocarditis caused by R. aeria in a patient taking tumor necrosis factor (TNF)-α blocker.
