The proteobacterial genus Helicobacter is composed of gastric species, all of them urease-positive, and enteric species (gastrointestinal, intestinal, hepatic, biliary), some of them urease-positive, others not. Here, we point out that the gastric species are divided in at least two phylogenetic groups, one is homogeneous, clearly separated from the enteric species, and another is forming a tight cluster within the enteric species. This feature is apparent in the phylogeny of the genus as… CONTINUE READING
