This book focuses on immune reactions and interactions of humans with Helicobacter pylori - a human pathogen connected to gastritis, peptic ulcers and even gastric cancer. With nearly half of the world's population colonized, it has been characterized as one of the most successful pathogens for more than 100,000 years of co-evolution with its host. The respective chapters discuss not only how H. pylori infection is considered a paradigm for persistent bacterial infection and chronic inflammation, but also how the infection might be connected to host protection against gastro-esophageal diseases, asthma, and other allergic disease manifestations. Readers will gain essential insights into the roles of specific factors in the immune response and learn about the impact of genetic polymorphisms on the risk of gastric carcinogenesis. In addition, the book discusses the strategies used by this bacterium, which allow it to colonize specific sites in the stomach, interact withthe microbiome, evade immune surveillance and undermine the resolution of inflammation during persistent infection.
