Outline of Final Research Achievements

This study examined dynamics of microbiota in chicken caecum upon C. jejuni infection. Clostridia was mostly dominant at 2 weeks-age chickens, and C. jejuni infected birds exhibited spatiotemporal increase in the yields of Faecalibacterium spp. The qPCR and FISH approaches then verified this genetic dynamics. Infiltration of Heterophiles toward caecum were significantly increased at early course of C. jejuni infection. Corroborating, chicken macrophage-like cell line HD-11 exhibited increased NO responses upon C. jejuni infection. C. jejuni also stimulated expression of several inflammatory-related genes such as TLR2/4/9.
