title: Detection of pathogen-related oral spirochetes, Treponema denticola, and Treponema socranskii in dental plaque from dogs.
abstract: Spirochetes have been observed in dental plaque from dogs, but specific spirochetes have not been identified. In particular, it is not known whether treponemes associated with periodontal diseases in humans also occur in dogs, and whether, like in humans, detection of specific treponemes correlates with periodontal status of dogs. Forty-two dogs were grouped according to the worst periodontal condition in the mouth, as determined by overt signs of inflammation and pocket probing depths. A representative specimen of dental plaque was obtained by pooling subgingival plaque collected from three uniform reference sites, irrespective of periodontal status at selected sites. The presence of pathogen-related oral spirochetes. Treponema denticola, and T. socranskii was determined using specific monoclonal antibodies in an immunocytochemical microscopic assay. All three treponemes were detected in all groups, but a significantly greater proportion of dogs with pocket probing depths > or = 5 mm had detectable treponemes, compared to dogs that were in periodontal health.
