Helicobacter is a genus of Gram-negative Epsilon Proteobacteria with characteristic helix shaped cells and are often found in the lining of the upper gastrointestinal tract of mammals and some birds. Helicobacter pylori infects up to 50% of the human population and is strongly associated with peptic ulcers, chronic gastritis, duodenitis, and stomach cancer.

Helicobacter mustelae is a pathogen of ferrets, where it causes general pathology and ulceration in a similar manner to H. pylori in humans. It provides a genetically tractable animal model for ulceration and gastric cancer. The Sanger Institute has been funded by the Wellcome Trust to sequence the genome of Helicobacter mustelae strain ATCC 43772 in collaboration with Dr. Paul O'Toole of the Department of Microbiology, University College Cork, Ireland. Comparative genome analysis of H. pylori, the extragastric H. hepaticus, and H. mustelae, will provide new insights into genes involved in gastric and extragastric virulence in this genus. This analysis has recently been published by O’Toole et al. (PMID: 20219135).
The Sanger Institute has initiated a Wellcome Trust project to sequence the genomes of representative of each of the major Helicobacter species in collaboration with Brendan Wren of the London School of Hygiene and Tropical Medicine.

Data Use Statement
This sequencing centre plans on publishing the completed and annotated sequences in a peer-reviewed journal as soon as possible. Permission of the principal investigator should be obtained before publishing analyses of the sequence/open reading frames/genes on a chromosome or genome scale. See our data sharing policy.
