In the past decade, researchers have begun to appreciate the importance of a two-way communication that occurs between microbes in the gastrointestinal tract and the brain, known as the gut–brain axis.
Gut bacteria can influence brain health, according to a study of mice genetically predisposed to develop Alzheimer’s-like brain damage. The study, by researchers at Washington University School of Medicine in St. Louis, indicates that gut bacteria produce compounds that influence the behavior of immune cells, including ones in the brain that can cause neurodegeneration. The findings suggest a new approach to treating Alzheimer’s and other neurodegenerative diseases.
Scientists at Ningbo University, China have identified biomarkers that could provide an early warning system for three common and dangerous pregnancy complications: pre-eclampsia, gestational diabetes, and a liver condition called intrahepatic cholestasis.
Review of over 300 studies sifts out relationships between metabolites and health worth a further look.
The opportunistic bacterium Acinetobacter baumannii rarely sickens healthy people but causes serious infections in hospitalized patients. A study, in mice, from Washington University School of Medicine in St. Louis suggests that Acinetobacter can hide undetected in bladder cells and then reactivate when stimulated by medical intervention. The findings suggest that patients may bring Acinetobacter into hospitals and that screening patients could supplement current infection-control efforts.
All chlamydiae today live inside the cells of hosts ranging from amoeba to animals. A team of scientists from the University of Vienna and the Wageningen University & Research found that the ancestor of chlamydiae likely already lived inside host cells, but that chlamydiae infecting amoeba evolved later in ways unexpected for intracellular bacteria. The study published in Nature Microbiology is an important step for understanding the emergence and evolution of endosymbiotic bacteria, including human pathogens.
RUDN ecologists, together with colleagues from the Pushchino Scientific Center for Biological Research of the Russian Academy of Sciences, have discovered bacteria that can decompose toxic substances in urban dust. The activity of these bacteria can be used to judge the ecological situation in the city.
With the world’s population topping 8 billion last year, it’s clear that humans have achieved a unique status in Earth’s history. We are the only creature that dominate all other organisms on the planet, from animals and fungi to plants and microbes.
DOE funding allows researchers to gain closer look into plant-microbe symbioses.
عزيزتي مايو كلينك: تصر صديقتي على أن تناول مكملات البروبيوتك الغذائية ساعدها على خسارة 50 رطلاً من خلال التحكم في بكتيريا الأمعاء. هل سيساعدني تناول البروبيوتك إلى جانب اتباع نظام غذائي متوازن وممارسة الرياضة على إنقاص الوزن؟
ESTIMADA MAYO CLINIC: Minha amiga insiste em dizer que tomar um suplemento probiótico a ajudou a perder 50 kg mantendo as bactérias intestinais em dia. Tomar probióticos junto com uma dieta balanceada e a prática de exercícios vai me ajudar a perder peso?
ESTIMADA MAYO CLINIC: Mi amigo asegura que tomar un suplemento probiótico le ha ayudado a perder 15 kilos manteniendo sus bacterias intestinales bajo control. ¿Tomar un probiótico en combinación con una alimentación equilibrada y ejercicio físico me ayudará a perder peso?

The use of synthetic food dyes such as Allura Red has increased significantly over the last several decades, but there has been little earlier study of these dyes’ effects on gut health. Khan and his team published their findings in Nature Communications. “What we have found is striking and alarming, as this common synthetic food dye is a possible dietary trigger for IBDs. This research is a significant advance in alerting the public on the potential harms of food dyes that we consume daily,” he said.
In many countries, the number of fig trees have been declining. While there are numerous explanations, one key problem is fig-wilting disease. A recognized cause of this disease is a fungus, Ceratocystis ficicola, which is transmitted by an ambrosia beetle, Euwallacea interjectus.
New research at Cleveland Clinic expands the link between what we eat and how the gut microbiome impacts our susceptibility to develop different diseases – in this case, how a specific gut microbe-generated byproduct is linked to heart failure risk.
A Rutgers study shows how digestive inflammation may drive MS and provides further evidence that more fiber by combat the condition.
Research from the lab of Fangqiong Ling at Washington University in St. Louis showed earlier this year that the amount of SARS-CoV-2 in a wastewater system was correlated with the burden of disease — COVID-19 — in the region it served.
Soil microbes decompose organic matter into simple carbon compounds – what soil conditions do these microbes prefer and where do they work most efficiently?
