Isolation of the provisionally named Desulfovibrio fairfieldensis from human periodontal pockets.
Sulfate-reducing bacteria have recently been associated with periodontitis and proposed to play a role in the pathogenesis of this chronic inflammatory process. Eight isolates of sulfate-reducing bacteria belonging to the genus Desulfovibrio were obtained from the periodontal pockets of five out of seven patients presenting with active periodontitis. A multiplex PCR was devised for their identification at the species level. All isolates were identified as Desulfovibrio fairfieldensis, a recently proposed new species. This finding reinforces the suggestion that Desulfovibrio fairfieldensis is a human bacterium that may present a pathogenic potential.
