About

Strongly evidence supports that H. pylori eradication is an effective approach to reduce the incidence of those pathologies. However, due to the increasing resistance rates to antibiotics, failures of H. pylori eradication get more and more common. Thus, rescue therapy for persistent H. pylori infection is becoming a grand challenge the investigators have to face.
