Temporal change in the Namibian Ju|’hoansi intestinal microbiome
… reside in our digestive tract comprise the human intestinal microbiome (IM). Many historical events have influenced the composition of our IM, such as the invention of cooking, the advent of farming and the industrial revolution. Although ancestral IMs could provide insight into the evolution of …

Towards a Better Understanding of Poultry Intestinal Microbiome through Metagenomic and Microarray Studies
<p>The intestinal microbiome in poultry tracts functions as an interface between the host and the feed ingested and has important roles in nutrition and health of the host. This intestinal microbiome consisting of bacteria, archaea, fungi and few protozoa, with bacteria being the most abundant …

Characterization of the intestinal microbiome and lactobacilli community: influence of dietary and environmental factors
The human gastrointestinal (GI) tract is colonized by a dense and diverse bacterial community called the commensal microbiota, which plays an important role in overall health of individuals. However, due to the extreme complexity of microbiota composition and limits of research tools, there were …

The association of early childhood nutrition and growth with the intestinal microbiome and pneumonia
… significantly to under-5 mortality. The gut microbiome is associated with development of malnutrition and pneumonia. However, data on longitudinal growth, infant feeding practices, and the microbiome in children with malnutrition and pneumonia in low and middle-income countries (LMIC) are …

Impact of cross-fostering on the intestinal microbiome and mucosal immune gene expression in neonatal pigs
… known about the impact of cross-fostering on the intestinal microbiome and mucosal immune gene expression of the neonatal pig. Twenty-four piglets were enrolled in the study to determine the influence of maternal microbial communities and to establish a baseline for mucosal immune gene expression …

Investigating novel treatment approaches to combat Clostridioides difficile
… and Prevention (CDC), capitalizes on disrupted intestinal microbiome to establish infection with disease symptoms ranging from mild diarrhea to potentially fatal conditions. Disruption of the intestinal microbiome, caused mostly by antibiotic use, enables C. difficile to colonize and proliferate …

The relationship between enteral nutrition, energy metabolism and gut homeostasis during the course of critical illness.
Nutrition has an indirect effect on the gastrointestinal function of the host and thereby on health, mainly by influencing the composition and activity of the human gut microbiota. The aim of this PhD project was to investigate the effect of nutrition as a factor affecting the intestinal …

Interactions Between Gut Microbial Composition, Mucosal Immunity and Metabolism
While evidence that the intestinal microbiome contributes to host health and disease has rapidly developed, the causal mechanisms that link these microbes to disease are largely elusive. The goal of this project was to explore the complex crosstalk between the microbiome and the immune system using …

Characterization of Bacterial Metabolites Involved in Host Pathogen Resistance
<p>The intestinal microbiome can mediate host resistance to enteric pathogens by modulating host immunity or by directly inhibiting pathogen growth and virulence. Although the abundance and diversity of bacterial metabolites in the intestine is appreciated, the majority of intestinal bacteria and …
