    Impact of feed additives and host-related factors on bacterial metabolites, mucosal integrity and immune response in the ileum of broilers

    HoloFood partners from the Freie University of Berlin (PhD student Yada Duangnumsawang, Prof. Jürgen Zentek, Dr. Wilfried Vahjen and Dr. Farshad Goodarzi Boroojeni) together with Joan Tarradas (IRTA) published a peer reviewed article aimed to investigate the effect of age, breed, and sex of chicken broilers, as well as a probiotic or phytobiotic product on mucosal morphology, bacterial metabolites, and immune traits in the ileum of broilers.

    Alterations in bacterial metabolites, cytokines, and mucosal integrity in the caecum of broilers caused by feed additives and host-related factors

    Results of the metabolic profiles from the HoloFood chicken trials are outlined focusing on the impact of age and diet. The results showed that bacterial metabolites could play a significant role in mucosal development and immunological response in the caecum of broilers.

    A strategic model of a host–microbe–microbe system reveals the importance of a joint host–microbe immune response to combat stress-induced gut dysbiosis

    Microbiomes provide key ecological functions to their host; however, most host-associated microbiomes are too complicated to allow a model of essential host–microbe–microbe interactions. The intestinal microbiota of salmonids may offer a solution since few dominating species often characterize it. We present one of the first models able to describe a, albeit simple, complete intestinal microbiome community of a vertebrate host. Our model stands out from predecessors by considering realistic parameters of the host immune function, a mutualist microbe able to induce host immune reactions, and a toxin-producing pathogenic microbe.

    Novel strategies to improve chicken performance and welfare by unveiling host-microbiota interactions through hologenomics

    In this paper, we introduce the animal trials conducted with broiler chickens in the H2020 project HoloFood, and our strategy to implement hologenomic analyses in light of the initial results, which despite yielding negligible effects of tested feed additives, provide relevant information to understand how host genomic features, microbiota development dynamics and host-microbiota interactions shape animal welfare and performance.

    Microbiome “Inception”: an Intestinal Cestode Shapes a Hierarchy of Microbial Communities Nested within the Host

    A new research article on endoparasite - host relationship in salmon by HoloFood researchers is published in mBio with some surprising insights. The results suggest that parasit cestodes may be themselves holobionts within the microbiomes of their fish host - emphasizing the importance of also considering microbes associated with parasites when studying instestinal parasitic infections.

    Review: Development and Functional Properties of Intestinal Mucus Layer in Poultry

    A new review article in the journal Frontiers in Immunology by PhD student Yada Duangnumsawang, Prof. Jürgen Zentek and Dr. Farshad Goodarzi Boroojeni from Freie Universität Berlin, explores the importance of the intestinal mucus in the poultry gut. The mucosal barrier of the gut is the first line of defence against the invasion of pathogens, supporting the colonization of beneficial bacteria and maintaining the proper environment for digestion. In spite of its great importance, little is known about the structure and functional properties of the intestinal mucus layer within the chicken gut. This review expands on our current understanding of this important intestinal mucus, the impact of age on the development of the cells that are a part of it as well as the dietary factors that impact them.
