Description and significance

Porphyromonas gingivalis was initially discovered in 1980 and classified asBacteriodes gingivalis. Subsequently, this organism was reclassified in 1988 due to its marked difference in chemical and biochemical properties from Bacteriodes.

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]

Genome structure

Select a strain for which genome information (e.g. size, plasmids, distinct genes, etc.) is available.

Cell structure and metabolism
