Gut Microbiome in Health and Disease (2nd Edition)

Dear Colleagues,

There is an increasing interest in elucidating how the gut microbiome modulates our physiology, both in health and disease. Recent technological advancements and expanded efforts have led to tremendous growth in our collective knowledge of the host microbiome. The purpose of this Special Issue is to collect what is known about the gut microbiome and how it is connected to the development of disease, and to identify the bacterial and biochemical targets. In addition, this Special Issue is also concerned with the nutrition–gut microbiome–physiology axis.

This Special Issue welcomes research papers and reviews that cover a wide range of topics, including food nutrition and the gut microbiome, as well as metabolite biomarkers and underlying mechanisms. We hope to expand upon what is currently known about the gut microbiota in this Special Issue by collecting cutting-edge findings in order to shed light on how the gut microbiome can control health and disease.

Abstract: Broiler cecal microbiota is an important for improving host health and its composition can be affected by various factors, such as diet, age, species, breed, regions, and environments. The objective of this study was to evaluate the impact of probiotics on cecal microbiota in broiler chicken at 7- and 35 d. The 16S rRNA gene amplicon sequencing of fecal microbiota was conducted from broiler divided into four groups: (1) control fed normal diet (2) B. subtilis (3) essential oil (4) B. velezensis. Firmicutes and Bacteroidota were the first and second most dominant phyla in all the samples, respectively. At the genus level, Romboutsia, Paeniclostridium, and Turicibacter were the most abundant in the B. substilis while Akkermansia, Bacteroides, and Monoglobus were the most abundant in the oregano oil group.
