Core Tip
Core tip: The main problem of Helicobacter pylori (H. pylori) infection management is linked to antibiotic resistances. They are due to point mutations in bacterial DNA. Polymerase chain reaction-based, culture-free techniques on gastric biopsy samples are accurate in finding minimal traces of genotypic resistant and hetero-resistant strains. The need for endoscopic procedure is the most important limit to their spread. Therefore, the further step has been the detection of point mutations in bacterial DNA fecal samples. There is increasing evidence of potential availability of noninvasive investigations able to detect H. pylori resistances to antibiotics, which may lead to tailored first-line therapies.
