Description and significance
Give a general description of the species (e.g. where/when was it first discovered, where is it commonly found, has it been cultured, functional role, type of bacterium [Gram+/-], morphology, etc.) and explain why it is important to study this microorganism. Examples of citations [1], [2]
Porphyromonas gingivalis is found in 86% of subgingival plaque samples from patients suffering from chronic periodontitis. P. gingivalis is a non-motile, asaccharolytic, obligate anaerobe, gram negative, rod shaped bacterium. It is known to form black pigmented colonies after being culture for 6-10 days on blood agar due to accumulation of heme. It requires iron for its growth. P. gingivalis was previously named Bacteroides gingivalis before reclassification into a new genus. It is a secondary colonizer of dental plaque which adheres to primary colonizer such as Streptococcus gordonii and P. intermedia.
