The intestinal lumen contains an abundance of bacteria, viruses and fungi alongside ingested material that shape the chronically active intestinal immune system from early life to maintain the integrity of the
pylori infection increased the diversity of the intestinal microbiota, reduced the abundance of Bacteroidetes, augmented the abundance of Firmicutes, and produced short-chain fatty acid-producing bacteria such as Akkermansia. All these factors may decrease vulnerability to IBD. Further studies investigating...
Bacteria called Helicobacter pylori (H. pylori) are thought to change food into chemicals that change the cells. An H. pylori infection does not always cause IM, but it increases the risk. The following are other factors that can increase your risk for IM:...
Gastrointestinal infectious diseases are prevalent in developing countries, and Ethiopia is of no exception. Despite the control measures in place, the magnitude and impact ofHelicobacter pyloriand intestinal parasitic infections and co-infection are on the rise. This study provides some basic information...

Using a gnotobiotic mouse model, we demonstrated the effect of gut bacteria-derived PUT, the most abundant polyamine in the human intestinal lumen [66,67], on colonic epithelial cell proliferation [19]. This model involved two strains ofEscherichia coli: a PUT-synthesizing wild-type strain (WT...
and the proportions between primary and secondary bile acids were not different in the proximal and mid-small intestine (duodenum and jejunum) between WT and Fut2-/- Western diet–fed mice (Figure 11A), which indicates an important role of bile acid–metabolizing bacteria in the distal small ...
Using organoids, researchers have been able to study the complete processes of virus, bacteria, and eukaryotic parasites adhesion, invasion, infection, and replication within epithelial cells. For instance, in 2015, a study found that Salmonella enterica serovar Typhimurium could invade the epithelial ...
