Nonpathogenic bacterium isolated from rumen that contains numerous pathogenic genes. Wolinella succinogenes DSM 1740

Wolinella succinogenes strain DSM 1740. This organism was first isolated from the rumen of a cow and is considered nonpathogenic in both its host and in humans. However, this organism contains a number of virulence genes, including some found within genomic islands, which resemble genes from Campylobacter jejuni. These include a chromosomal type IV secretion system that resembles that found on the Campylobacter jejuni virulence plasmid pVir, and the Campylobacter jejuni secreted invasion antigen B (ciaB). The chromosome also contains nitrogen-fixation genes that may have been horizontally-transferred from bacteria within the Rhizobiaciae group.
