Abstract
Modern management of chicks hinders the vertical transmission of intestinal microbiota, which is closely related to immunity. Inulin is a substrate that can be utilized by the microbiota. This study aimed to determine whether fecal microbiota transplantation (FMT) combined with inulin played a "1 + 1 > 2" role in enhancing the development and function of immune organs. Chicks were treated with 1 % inulin and/or fecal microbiota suspension on days 1-6. The growth performance, immune organ development, and immune indicators were evaluated on days 7, 14, and 21. Results showed that the combination of FMT and inulin significantly increased the immune organ index on day 7 and promoted the morphological structure and the expression of proliferating cell nuclear antigen (PCNA) in immune organs on days 7, 14, and 21. Each treatment increased the gene expression of interferon-gamma (IFN-γ), interleukin-4 (IL-4), interleukin-2 (IL-2), B cell-activating factor receptor (BAFFR), B cell linker (BLNK), C-X-C Motif Chemokine Ligand 12 (CXCL12), C-X-C Motif Chemokine Receptor 4 (CXCR4), and Biotin (Bu-1) to varying degrees. FMT combined with inulin significantly increased the expression of IgA-positive cells on days 7 and 14. In conclusion, the synergistic effect of FMT and inulin had beneficial impacts on the development and function of immune organs.
期刊介绍:
The Journal of Biotechnology has an open access mirror journal, the Journal of Biotechnology: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
The Journal provides a medium for the rapid publication of both full-length articles and short communications on novel and innovative aspects of biotechnology. The Journal will accept papers ranging from genetic or molecular biological positions to those covering biochemical, chemical or bioprocess engineering aspects as well as computer application of new software concepts, provided that in each case the material is directly relevant to biotechnological systems. Papers presenting information of a multidisciplinary nature that would not be suitable for publication in a journal devoted to a single discipline, are particularly welcome.
