Species

Porphyromonas gingivalis

Type strain: 2561 = ATCC 33277 = BCRC 14417 = CCRC 14417 = CCUG 25893 = CCUG 25928 = CIP 103683 = Coykendall 2561 = DSM 20709 = JCM 12257 = KCTC 5121 = NCTC 11834 = Slots 2561 [4][5]

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] 

Etymology: N.L. fem. dim. n. Veillonella, named after Adrien Veillon, the French microbiologist who isolated the type species.

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.

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.
