	abstract = {Background: Helicobacter pylori (H. pylori) is a Gram-negative pathogenic bacterium that causes chronic gastritis and other gastric diseases in humans. In Tibet, China, the infection of H. pylori is an important risk factor that caused gastric cancer.
Methods: To understand the characteristics of this pathogen in Tibet, five strains of H. pylori were isolated from three patients’ oral cavity or stomach who had either a gastric ulcer or gastritis. We performed genome sequences of these five clinical strains on Illumina Hiseq, and 55,016-63666 SNVs/InDels were identified by comparing to the reference strain of H. pylori 26995.
Results: The phylogenetic analysis with multi-locus sequence typing (MLST) showed that five Tibetan strains were defined as hpEurope population and their proteins encoded by the cagA gene also presented a western type. Also, the strains that were isolated from the same patients’ oral cavity and stomach exhibited homology in molecular evolution.
Conclusions: This is the first study to investigate the phylogenetic population structure of the epidemic strains of H. pylori in Tibet, which may improve cognition of Tibetan strains and confirm the homology of the strains from oral cavity and stomach.},
