Porphyromonadaceae

Porphyromonadaceae is a family of Gram-negative bacteria described by Noel R. Krieg in 2015. It contains nine genera, five of which are validly published by the International Code of Nomenclature of Prokaryotes.^[2] Bacteria with 16S ribosomal RNA highly similar to the Porphyromonas genus, as compared to the larger taxonomic order Bacteroidales, are classified in this family.^[1]

Bacteria of the Porphyromonadaceae family have coccobacilli shapes, and are obligately anaerobic, non-spore forming, and non-motile. Many of its species are members of animal gastrointestinal and oral microbiomes, such as Porphyromonas gingivalis, which causes periodontal disease.^[3]
