Discovery of unique African CagA-multimerization motif in the Dominican Republic.

Background: () colonizes the human stomach and is a major cause of peptic ulcer disease and gastric cancer. However, although the prevalence of is high in Africa, the incidence of gastric cancer is low, and this phenomenon is called to be African enigma. The CagA protein produced by is the most studied virulence factor.

Comparative study between Helicobacter pylori and host human genetics in the Dominican Republic.

Background: Helicobacter pylori, a bacterium that infects the human stomach, has high genetic diversity. Because its evolution is parallel to human, H. pylori is used as a tool to trace human migration.

Five alternative Helicobacter pylori antibiotics to counter high levofloxacin and metronidazole resistance in the Dominican Republic.

The prevalence of Helicobacter pylori resistance to levofloxacin and metronidazole was high in the Dominican Republic. We used two-fold agar dilution method to determine the minimum inhibitory concentration of five alternative antibiotics in 63 Dominican strains. We also assessed the genetic mutations associated with the antibiotic resistance using next-generation sequencing.

Clarithromycin-Based Triple Therapy is Still Useful as an Initial Treatment for Infection in the Dominican Republic.

Abstract antibiotic susceptibility in the Dominican Republic has not been monitored. We assessed antibiotic susceptibility in the Dominican Republic, and analyzed mutations associated with antibiotic resistance. We recruited 158 dyspeptic patients in Santo Domingo and used agar dilution to test susceptibility to five antibiotics.
