Abstract
We present the case of a 50-year-old man presenting with fever, back pain, persistent bacteremia with Veillonella dispar, echocardiographic evidence of a tricuspid valve vegetation increasing in size, and magnetic resonance imaging suggesting new vertebral osteomyelitis. He was successfully treated with intravenous ceftriaxone for six weeks. Deep-seated infections secondary to Veillonella species are rare, but cases of endocarditis, osteomyelitis, and meningitis have been reported in the literature. Given Veillonella species are normal human commensals present in the oropharyngeal flora, we suspect our patient developed native tricuspid valve endocarditis and vertebral osteomyelitis as a complication of either poor dentition or contaminated injection drug use paraphernalia and subsequent hematogenous seeding.
