Outline of Final Research Achievements

We are exposed to many types of microorganisms in the surrounding environment, however, not all microorganisms can cause infectious disease. There should be a mechanism by which the host discriminate a bacteria between pathogen and non-pathogen, however, it is not fully understood. In this study we investigated whether regulatory cytokine IL-10 plays a role in the pathogen non-pathogen discrimination. Our data suggested that non-pathogenic bacteria Nissle 1917 has an ability to induce IL-10 superior to pathogenic C.roudentium. Only live but not heat-killed Nissle 1917 showed that ability.
