Abstract: Biofilm formation plays an important role in gastrointestinal tract recurrent refractory infections caused by Helicobacter pylori. This review discusses the formation and structure, formation kinetics and quorum sensing system of Helicobacter pylori biofilm, in order to describe the recent advances in the research direction of its drug resistance mechanism. There includes 4 theories, osmosis and nutrient limitation, fighting against immune system, horizontal gene transfer and the anomaly expression of efflux pump genes. This review also summarizes the research progress of prevention strategies to Helicobacter pylori biofilm.

Key words: Biofilm, Drug resistance, Relationship
