The genome of the type strain was sequenced as part of the GEBA (Genomic Encyclopedia of Bacteria and Archaea) project.
The separation of Porphyromonas gulae and Porphyromonas gingivalis into distinct species was confirmed by the 16S-23S rRNA gene internal transcribed spacer (ITS) data.Publication:
