While patients infected with SARS-CoV-2 typically present with a respiratory illness, certain patients also report gastrointestinal symptoms. The presence of virus receptors in gastrointestinal epithelial cells and an altered gut microbiota composition in some patients might have implications for managing COVID-19.

Whether bacterial colonization starts in utero is still a matter for scientific debate. The study of the fetal intestinal content collected from terminated pregnancies reveals some evidence for early bacterial colonization linked to distinct immune imprinting.

Gut microbiota, with its close links to metabolism and the immune system, could potentially be a factor that lies at the core of good health. This means it can be positioned at the heart of the processes that influence the risk of contracting different diseases.

Gut microbiome responses to antibiotics and their long-lasting effects on the host remain poorly characterized. A new mice study shows that amoxicillin-clavulanate for 7 days leads to personalized changes in gut microbiota composition and colonic transcriptome.
Circadian rhythms are also apparent within our gastrointestinal tract. Two new mice studies show that circadian rhythm and clock genes may also affect intestinal immune cells by boosting the secretion of cytokines that help maintain proper balance of the intestinal barrier.

Imbalances in the gut microbiota composition have been described as a hallmark of certain liver diseases. Yi Duan from the University of California San Diego and colleagues have found in mice that specific phages targeting the gut-dwelling bacterium E. faecalis might be used to treat patients with alcoholic hepatitis.

The causal contribution of commensal gut microorganisms in human immune responses is limited. A new study has found that disruptions in the gut microbiome secondary to antibiotics may adversely affect immunity to influenza vaccination in healthy adults.

Scientists struggle to understand why some gut bacteria are sensitive to antibiotics while a fraction of them survive treatment. New research in mice reveals that gut microbial metabolism alongside diet play a key role in modifying the extent of gut microbiome disruption in response to antibiotics.

The gut microbiota is a promising target to suppress food allergies through acting via regulatory T cells. New research in mice shed light on mechanisms by which early-life gut microbiota exerts a protective effect against IgE-mediated food allergies.

The mechanisms that link changes in gut microbiome composition and an increased risk of cardiovascular disease remain elusive. Changes in the gut microbiome related to aging may mediate arterial dysfunction, coupled with a normalization of inflammation, suggests a new mice study.
