Epidural abscess caused by Veillonella parvula: Case report and review of the literature

Abstract

Veillonella parvula, an anaerobic, Gram-negative coccus is part of the normal flora of the oral, gastrointestinal, respiratory, and genitourinary tracts in humans and animals. We herein present a case of epidural abscess caused by V. parvula in a 68-year-old man with sinus squamous cell carcinoma who presented with a 3-week history of low back pain. Blood and pus cultures were positive for Veillonella spp. After sequencing of the 16S ribosomal DNA, the pathogen was identified as V. parvula. Surgical debridement was performed following which the patient received intravenous administration of amoxicillin/clavulanate. To our knowledge, there are only seven reported cases of spinal infection caused by Veillonella spp. and these are reviewed here.
