Was isolation of Veillonella from spinal osteomyelitis possible due to poor tissue perfusion?

From a needle biopsy of the body of the 12th thoracic vertebra in a 74-year-old man with spinal osteomyelitis a Veillonella parvula was isolated. The significance of this bacterium as lactic acid indicator has been considered and discussed. Since this strictly anaerobic bacterium mainly uses lactic acid for energy generation, lactic acid must continuously and sufficiently have been produced in or near to the vertebrate body to permit outgrowth of this bacterium. Since neither microbial infections nor tumours could be demonstrated, we finally hypothesised that in this patient poor tissue perfusion has been the primary cause of lactic acid production.
