Gut microbiota acts like an auxiliary liver, study finds
Microbes in the mammalian gut can significantly change their hosts' amino acid and glucose metabolism, acting almost like an extra liver, according to a new preclinical study by Weill Cornell Medicine investigators.

Research suggests bacteria may be present in the human GI tract before birth. But coherent experimental approaches are needed to determine whether bacteria actually colonize pre-birth.

Scientists unveil 'atlas' of the gut microbiome
Scientists unveil 'atlas' of the gut microbiome
A new computational tool has allowed scientists to map how microbes interact in the gut, and it could one day be used to develop more-targeted therapies for diseases.
The participants who provided samples spanned 15 countries and either had one of 11 diseases where the gut microbiome has previously been implicated — such as IBD, type 2 diabetes or colon cancer — or did not have any of these conditions. For 10 of the 11 diseases, the team was able to pinpoint specific interactions between microbes that appeared to be disrupted, compared with the people who lacked these conditions; these disruptions stemmed from the microbes missing their corresponding "feeding" partners.

How plant-derived nutrients can affect the gut and brain
How plant-derived nutrients can affect the gut and brain
Can plant-derived nutrients alter gut bacteria to affect brain function? Scientists from the University of Leipzig Medical Center, the Max Planck Institute for Human Cognitive and Brain Sciences and the Helmholtz Center for Environmental Research investigated this question in a study of overweight adults.
These indigestible dietary fibers are found in plant-derived foods such as onions, leeks, artichokes, wheat, bananas, and in high concentrations in chicory root. They support gut health by promoting the growth and activity of beneficial gut bacteria.

Metagenomic assessment of gut microbial communities and risk of severe COVID-19 | Genome Medicine | Full Text
Background The gut microbiome is a critical modulator of host immunity and is linked to the immune response to respiratory viral infections. However, few studies have gone beyond describing broad compositional alterations in severe COVID-19, defined as acute respiratory or other organ failure. Methods We profiled 127 hospitalized patients with COVID-19 (n = 79 with severe COVID-19 and 48 with moderate) who collectively provided 241 stool samples from April 2020 to May 2021 to identify links between COVID-19 severity and gut microbial taxa, their biochemical pathways, and stool metabolites. Results Forty-eight species were associated with severe disease after accounting for antibiotic use, age, sex, and various comorbidities. These included significant in-hospital depletions of Fusicatenibacter saccharivorans and Roseburia hominis, each previously linked to post-acute COVID syndrome or “long COVID,” suggesting these microbes may serve as early biomarkers for the eventual development of long COVID. A random forest classifier achieved excellent performance when tasked with classifying whether stool was obtained from patients with severe vs. moderate COVID-19, a finding that was externally validated in an independent cohort. Dedicated network analyses demonstrated fragile microbial ecology in severe disease, characterized by fracturing of clusters and reduced negative selection. We also observed shifts in predicted stool metabolite pools, implicating perturbed bile acid metabolism in severe disease. Conclusions Here, we show that the gut microbiome differentiates individuals with a more severe disease course after infection with COVID-19 and offer several tractable and biologically plausible mechanisms through which gut microbial communities may influence COVID-19 disease course. Further studies are needed to expand upon these observations to better leverage the gut microbiome as a potential biomarker for disease severity and as a target for therapeutic intervention.

New data demonstrates potential role of probiotic supplementation in adults with major depressive disorder
A new study published 14 June in JAMA Psychiatry has found evidence that supplementing the diet with a probiotic blend containing 14 strains of bacteria can help individuals who are being treated for major depressive disorder with antidepressants. The research, led by the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King's College London and in partnership with ADM Protexin, part of ADM, demonstrated the potential of probiotic supplementation to support improvements in multiple depression and anxiety scores over an eight-week period.
