Core Tip
Core Tip: The World Health Organization designated clarithromycin-resistant Helicobacter pylori (H. pylori) a high priority among bacteria for antibiotic research and development, but the clarithromycin resistance mechanism remains unclear. We isolated and cultured clinical H. pylori strains, determined their minimal inhibitory concentrations, completed genome sequencing of hp1181 and hp1184 genes, analyzed their mutations, and found that the expression of the genes hp1184 and hp1181 was associated with clarithromycin resistance, which suggested that they can be used as genes for early diagnosis. This research may prove useful in the diagnosis, prevention, and treatment of clarithromycin-resistant H. pylori.
