Alloprevotella rava isolated from a mixed infection of an elderly patient with chronic mandibular osteomyelitis mimicking oral squamous cell carcinoma

Abstract The anaerobic, Gram-negative bacillus, Alloprevotella rava has recently been described in human oral cavity. To our knowledge, this species has not been isolated from chronic osteomyleitis samples. We presented the first case of A. rava infection in a 92-year-old patient with polymicrobial chronic mandibular osteomyelitis, mimicking oral squamous cell carcinoma.
