Porphyromonas gingivalis type strain ATCC 33277

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]

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.


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


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.
