Porphyromonas gingivalis

A non-motile, gram-negative, anaerobic bacillus of the phylum Bacteroidetes, which forms black colonies on blood agar. It is found in the oral cavity, where it causes periodontal disease by producing collagenase, and has been cultured from gastrointestinal and respiratory tract specimens and from patients with rheumatoid arthritis.
