Non-vertebral Veillonella species septicemia and osteomyelitis in a patient with diabetes: a case report and review of the literature

Introduction Veillonella is a nonfermentative, strictly anaerobic, Gram-negative coccus that forms part of the human gastrointestinal tract, mouth and vaginal flora. Like other anaerobic infection, Veillonella species usually are involved in polymicrobial processes, which make it difficult to determine their pathogenic role. Isolation of a clinically significant Veillonella species is rare and V. parvula is the most common one reported to cause infection in humans. The most frequently reported infection caused by V. parvula is osteomyelitis, almost always in association with bacteremia.
