Abstract:
Abstract Background Microbiota is most likely essential in the pathogenesis of Crohn’s disease (CD). Fecal diversion after ileocecal resection (ICR) protects against CD recurrence, whereas infusion of fecal content triggers inflammation. After ICR, the majority of patients experience endoscopic recurrence in the neoterminal ileum, and the ileal microbiome is of particular interest. We have assessed the mucosa-associated microbiome in the inflamed and noninflamed ileum in patients with CD. Methods Mucosa-associated microbiome was assessed by 16S rRNA sequencing of biopsies sampled 5 and 15 cm o

Abstract:
The abuse of antibiotics has become a serious health challenge in the veterinary field. It creates environmental selection pressure on bacteria and facilitates the rapid spread of antibiotic resistance genes. The speed of discovery and application of cost-effective alternatives to antibiotics is slow in pig production. Natural products from biosynthetic gene clusters (BGCs) represent promising therapeutic agents for animal and human health and have attracted extraordinary passion from researchers due to their ability to participate in biofilm inhibition, stress resistance, and the killing of c

Abstract:
The role of volatile fatty acids (VFAs) in ruminal fermentation is well studied, but their effects on the ileal microbiome and epithelial health remain less explored. In this study, we investigated the impact of the exogenous oral infusion of three VFAs, sodium acetate (NaAc), propionate (NaPr), and butyrate (NaBu), on the VFA concentrations in ileal contents, as well as ileal microbiome profiling and epithelial health parameters (inflammatory cytokine and tight junctions) in goats. The data demonstrated that the oral infusion of three VFAs can enhance VFA production by increasing the proporti

Abstract:
In the current era of precision oncology, it is widely acknowledged that CRC is a heterogeneous disease entity. Tumor location (right- or left-sided colon cancer or rectal cancer) is a crucial factor in determining disease progression as well as prognosis and influences disease management. In the last decade, numerous works have reported that the microbiome is an important element of CRC carcinogenesis, progression and therapy response. Owing to the heterogeneous nature of microbiomes, the findings of these studies were inconsistent. The majority of the studies combined colon cancer (CC) and r

Abstract Traditional evaluations of feed additives in swine diets have primarily focused on performance metrics, but improving nutrient utilization from high-fiber diets requires a deeper understanding of the interactions among diet, gut microbiome, and digestibility. Therefore, a multi-omics approach is necessary to explore these complex relationships. The objective of this study was to investigate the effects of dietary inclusion of an Aspergillus oryzae prebiotic (AOP; Amaferm®, BioZyme Inc.) on the gut microbiome and metabolome of growing pigs fed high-fiber diets, and to examine associati

Introduction: Inflammatory pouch complications, including pouchitis, chronic pouchitis (CP) and a Crohn’s disease-like phenotype (CDL) of the pouch following ileal pouch-anal anastomosis (IPAA), are relatively common, and arise via unknown mechanisms.

Abstract:
The role of the gut microbiota in modifying the pathophysiology of various diseases, including neurodegenerative diseases, is increasingly becoming clear. Bile acids have been shown to be endogenous factors that affect gut microbiota, and bile-acid metabolites directly or indirectly affect host physiology and pathophysiology. The development of metagenomic analysis for gut microbiota and systematic bile-acid measurement using LC–MS/MS has triggered a breakthrough for research in this field. Clinically, an inhibitor of the ileal bile-acid transporter (Elobixibat) was used as a therapeutic agent
