Comparative analysis of four Campylobacterales

Comparative genome analysis can be used to identify species-specific genes and gene clusters, and analysis of these genes can give an insight into the mechanisms involved in a specific bacteria-host interaction. Comparative analysis can also provide important information on the genome dynamics and degree of recombination in a particular species. This article describes the comparative genome analysis of representatives of four different Campylobacterales species - two pathogens of humans, Helicobacter pylori and Campylobacter jejuni, as well as Helicobacter hepaticus, which is associated with liver cancer in rodents, and the non-pathogenic commensal species, Wolinella succinogenes.
