The Porphyromonadaceae are a family of bacteria . The type genus is Porphyromonas . Some types can cause periodontal disease.

Appearance

Many species have rod-shaped cells, some are more like cocci , so they are more spherical. Tannerella forsythia has fusiform (spindle-shaped) rods. The rods of Paludibacter have round or slightly pointed ends. The species are not motile .

Growth and metabolism

All members of the Porphyromonadaceae are chemo-organotrophic . The metabolic pathway is usually fermentation .

Most of the species are anaerobic , some, such as species of Dysgonomonas , also show growth in the presence of oxygen (facultative anaerobic). The majority are saccharolytic, i. that is, they are able to ferment carbohydrates . An exception (asaccharolytic) is e.g. B. Proteiniphilum or Porphyromonas gingivalis .

Pathogenicity

The species Porphyromonas gingivalis can cause periodontitis . It is also associated with bad breath . Porphyromonas endodontalis is mostly isolated from infected root tubules. Tannerella forsythia can also be implicated in periodontal disease. The type Odoribacter denticanis is also associated with periodontitis.

Recent studies indicate that Porphyromonas gingivalis produces an enzyme that citrullinates certain proteins, which could stimulate the production of autoantibodies that cause rheumatoid arthritis .

Systematics

The family of the Porphyromonadaceae is placed in the order Bacteroidales in the department of Bacteroidetes . A selection of genera of the family follows:

The genus Oribaculum was reclassified as Porphyromonas in 1995 . The genera Butyricimonas , first described by Sakamoto et al. in 2009 and Odoribacter , described by Hardham et al. in 2008 are now managed under the family Odoribacteraceae .
