Species
Porphyromonas gingivalis strain 2561 = ATCC 33277= CCUG 25893 = CCUG 25928 = CIP 103683 = DSM 20709 = JCM 12257 = NCTC 11834.
Description and significance
Porphyromonas gingivalis was first discovered [1]. It is a pathogenic bacterium that has no functional role [2] and is commonly found in the oral cavity[3]. P. gingivalis is a gram negative, rod shaped bacteria that forms black pigmented colonies on blood agar plate [4]. It is important to study this microorganism as [5].

Genome structure
Select a strain for which genome information (e.g. size, plasmids, distinct genes, etc.) is available.
In 2003, the genome of p. gingivalis was described to have 2,343,479bp with an average guanine cytosine nucleotide content of 48.3%. It has 4 ribosomal operons, 2 structural genes and 53 tRNA gene. There was a total of 1990 open reading frames that could be identified in the genome. 21 areas of the genome were discovered to display an atypical nucleotide composition. The areas range in size from 11 to 68kb and has a guanine cytosine nucleotide content of between 29.4% to 61.6%. 463 genes were also seen in the genome [6][7]
