A member of the phylum Bacteroidetes and a non-motile, gram-negative, rod-shaped, anaerobic pathogenic bacterium, which is found primarily in the oral cavity. It is best known for causing periodontal disease due to gingipain proteases, a capsular polysaccharide, induction of host cell proliferation and digestion of chemokines that recruit neutrophils–which would otherwise destroy the bacteria. P gingivalis-induced periodontal disease has been linked to an increased risk of rheumatoid arthritis and Alzheimer’s disease. 

Synonyms Gum disease bacteria
