| Outline of Final Research Achievements |
We analyzed associations between infection with each pathogen and diarrheal episodes and found both E. histolyica and E. moshkovskii infections were associated with diarrheal episodes. Based on the immunological finding observed in children, we clarified the role of IL-17A during E. histolyica infection. In an animal model with chronic amebic colitis, augmented IL-17A expression was observed. In some of IL-17A deficient mice, ameba was expelled with increased IFN-g/IL-4 ratio, indicating IL-17A contributes to chronic infection with E. histolyica.
