is a pathogen related to severe diseases such as gastric cancer; because of rising antimicrobial-resistant strains, failure to eradicate with antibiotics has increased worldwide. Multidrug-resistant and gastric cancer is common in Mongolia; therefore, we aimed to explore alternative antimicrobial treatments and the genomes of resistant strains in this country. A total of 361 strains isolated from patients in Mongolia were considered.

Background: The prevalence of gastric cancer in Mongolia, in East Asia, remains the highest in the world. However, most strains in Mongolia have a less virulent Western-type CagA. We aimed to determine how genomic variation affected gastric diseases, especially gastric cancer, based on comprehensive genome analysis.

In this study, we evaluated the LA assay for diagnosing infection and predicting gastric mucosal changes in a Mongolian population.
Methods: : In total, 484 individuals were classified into -positive (n=356) and -negative (n=128) groups, as determined by histology and culture.
The use of serum anti- IgG and pepsinogen (PG) detection as a diagnostic method was evaluated in Sri Lanka. Gastric biopsies were performed (353 patients), and the prevalence of infection was 1.7% (culture) and 2.

Methods: We enrolled Mongolian volunteers with dyspepsia.
Mongolia has a high prevalence of infection and the second highest incidence of gastric cancer worldwide. Thus, investigating the prevalence of antibiotic resistance and its underlying genetic mechanism is necessary. We isolated 361 strains throughout Mongolia.

We aimed to examine gastric mucosal microbiota in HpN compared to -positive gastritis (HpP) and -negative non-gastritis group (control).

Methods: This was a case-control study in which upper gastrointestinal endoscopy, gastric histology, Helicobacter pylori testing, and risk factor questionnaires were obtained. Histologic subtypes were determined by Lauren's classification.
Background: Mongolia has not only the second highest incidence rate but also the highest mortality rate for gastric cancer globally. In addition to gastric cancer, ulcerative disease complications are also life threatening; thus, investigating infection and other risk factors is essential.
Results: infection was high in tested dyspeptic patients from all parts of Mongolia, with an overall infection rate of 80.
