Helicobacter pylori is a Gram-negative bacterium that persistently infects the human stomach inducing chronic inflammation. The exact mechanisms of pathogenesis are still not completely understood. Although not a natural host for H. pylori, mouse infection models play an important role in establishing the immunology and pathogenicity of H. pylori. In this study, for the first time, the genome sequences of clinical H. pylori strain UM032 and mice-adapted derivatives, 298 and 299, were sequenced using the PacBio Single Molecule, Real-Time (SMRT) technology.

After publication of this work [1], we discovered that due to an inadvertent and accidental mistake, Figure 4 and 5 in the original article were essentially the same figure. Amendment to Figure 5 has now been added. We offer our sincerest apologies for this oversight.
