Species

Kingella oralis

Type strain: strain UB-38 = ATCC 51147= CCUG 30450 = CIP 103803

Description and significance

Kingella oralis is a gram-negative facultatively anaerobic bacilli that grows in mesophillic environments and is isolated from human dental plaque. Kingella oralis is associated with periodontitis;

Genome structure

Kingella Oralis strain ATCC 51147 does not encode for chromosomes and plasmids. It has a total length of about 2.41mb, encodes for 2,315 proteins and has a GC content of 54.3%. Sequencing results show that ATCC51147 consists of 5 scaffolds (Scfld 0-4) with no gaps between, an assembly gap length of 700, and 12 contigs. It has 3,165 coding genes and 52 non-coding genes. However the functions of these genes are not yet known.

This strain has contains specialty genes that are of particular interest, such as antibiotic resistance genes, drug targets, virulence factors, and human homologs.

Select a strain for which genome information (e.g. size, plasmids, distinct genes, etc.) is available.
