Hence, eradication of this infection could prevent these diseases. The most popular first\u2010line treatment protocol to eradicate <jats:italic>H. pylori<\/jats:italic> is termed \u201ctriple therapy\u201d and consists of a proton pump inhibitor (PPI), clarithromycin, and amoxicillin or metronidazole. However, the antibiotics used to treat <jats:italic>H. pylori<\/jats:italic>  infection are hindered by the antibiotics\u2010resistant bacteria and by their antimicrobial activity against intestinal bacteria, leading to side effects.
