The microecological and immunological problems of persistention of Helicobacter pylori

The interrelation of persistence of Helicobacter pylori in stomach with innate and adaptive immunity of human has been discussed. The analysis of the mechanisms of immunological recognition of the antigens of this microorganism and response to them has been performed. It has been considered, that the development and course of gastritis and ulcer in human with Helicobacter pylori stipulate for inadequate reactions of immune system and common reactivity by the individual organism in presence of Helicobacter pylori in mucus of stomach.
