Its survival in the acidic stomach environment is due to virulence factors like urease, flagella, and adhesion proteins (BabA, SabA). Current treatments involve a combination of antibiotics (clarithromycin, metronidazole, amoxicillin, tetracycline) and proton pump inhibitors, but increasing antibiotic resistance, especially to clarithromycin and metronidazole, poses a major challenge. Resistance mechanisms include mutations in drug targets, efflux pump overexpression, and enzymatic degradation of antibiotics. This has prompted exploration of alternative therapies targeting bacterial processes like urease activity, biofilm formation, and metabolic pathways (energy production, amino acid synthesis, iron acquisition). Natural compounds, such as chitosan and plant extracts, show promise in combating H. pylori growth and virulence. Vaccine development is also ongoing, with DNA vaccines showing potential for broad immune responses. However, no vaccine is yet close to widespread clinical use.<\/jats:p>","DOI":"10.3390\/pathogens14070619","type":"journal-article","created":{"date-parts":[[2025,6,23]],"date-time":"2025-06-23T09:08:44Z","timestamp":1750669724000},"page":"619","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Challenges and Prospects for Eradication of Helicobacter pylori: Targeting Virulence Factors, Metabolism, and Vaccine Innovation"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5649-1089","authenticated-orcid":false,"given":"Adrian","family":"Bakiera","sequence":"first","affiliation":[{"name":"Department of Pharmaceutical Microbiology, Medical University of Lublin, 20-093 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-3953-1745","authenticated-orcid":false,"given":"Anita","family":"Solarz","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Microbiology, Medical University of Lublin, 20-093 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marika","family":"Kowalczyk","sequence":"additional","affiliation":[{"name":"Stefan Cardinal Wyszynski District Specialist Hospital, 20-718 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Halina","family":"Cicho\u017c-Lach","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology with Endoscopic Unit, Medical University of Lublin, 20-953 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1634-0387","authenticated-orcid":false,"given":"Izabela","family":"Korona-G\u0142owniak","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Microbiology, Medical University of Lublin, 20-093 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,6,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"\u00d6ztekin, M., Y\u0131lmaz, B., A\u011fag\u00fcnd\u00fcz, D., and Capasso, R.
