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

Cell wall, biofilm formation, motility, metabolic functions.

Ecology

Aerobe/anaerobe, habitat (location in the oral cavity, potential other environments) and microbe/host interactions.

P. gingivalis is an obligate anaerobe that is most commonly associated with the human oral cavity. However, it has also been identified

Pathology

Do these microorganisms cause disease in the oral cavity or elsewhere?

Application to biotechnology

Bioengineering, biotechnologically relevant enzyme/compound production, drug targets,…

Current research

Summarise some of the most recent discoveries regarding this species.
