The family porphyromonadaceae

Abstract

Porphyromonadaceae, a family within the order Bacteroidales, comprises the genera Porphyromonas, Barnesiella, Butyricimonas, Dysgonomonas, Macellibacteroides, Odoribacter, Paludibacter, Parabacteroides, Petrimonas, Proteiniphilum, and Tannerella. The type genus is the genus Porphyromonas. At first, this family comprised the genera Porphyromonas, Dysgonomonas, and Tannerella (Garrity GM, Bell JA, Liburn T (2005) The revised road map to the manual. In: Brenner DJ, Krieg NR, Staley JT (eds) Bergey's Manual of Systematic Bacteriology, The Proteobacteria, Part A, Introductory Essays, vol 2. 2nd edn New York, Springer pp 159-206). This family comprises five monospecific genera represented by Macellibacteroides fermentans, Paludibacter propionicigenes, Petrimonas sulfuriphila, Proteiniphilum acetatigenes, and Tannerella forsythia. Macellibacteroides fermentans and Parabacteroides chartae are phylogenetically highly related and should be considered strains of the same species, with Macellibacteroides fermentans having page priority. Members of the family are defined by a variety of cellular morphologies and chemotaxonomic characteristics. Many species of the family Porphyromonadaceae are part of the indigenous microbiota of the human and animal gastrointestinal tract and oral cavity, but some species in this family are commonly associated with a variety of human and animal infections.
