Porphyromonas is a Gram-negative, non-spore-forming, obligately anaerobic and non-motile genus from the family Porphyromonadaceae.[3][1][2][4] There were 16 different Porphyromonas species documented as of 2015, which reside in both animal and human reservoirs.[5] It was discovered more recently that Porphyromonas also exist in the environment, albeit to a lesser extent.[6] This genus is notably implicated in the modulation of oral cavity, respiratory tract, and gastrointestinal tract disease states.[5] It is suggested that Porphyromonas either operate as benign bacteria pertinent to host immunity or are potential pathobionts that opportunistically provoke diseased states when homeostasis is disrupted.[6] Despite its characterization not being fully elucidated due to sparse research, various studies report the prevalence of this genus at 58.7% in healthy states compared with 41.3% in diseased states.[6]
This genus was first reported in the oral cavity[5] and is found specifically in the salivary microbiome.[7] Porphyromonas are also commonly found in the microbiome of the human digestive tract, as shown by the Human Microbiome Project in general.[8]
