NewsSwitching to vegan or ketogenic diet rapidly impacts immune system - and gut microbiome
A study found that switching to a vegan diet prompted responses linked to innate immunity, while the keto diet elicited responses associated with adaptive immunity, along with metabolic changes and shifts in the gut microbiomes.

NewsGut microbiota influence severity of respiratory viral infection
The composition of microbiota found in the gut influences how susceptible mice are to respiratory virus infections and the severity of these infections, a new study reveals.

NewsProbiotics promote weight loss in obese dogs
Researchers have identified two strains of probiotics that can be used to reduce weight in obese dogs.

NewsStudying defensive bacteria in squid and newts may help human gut health
Elizabeth Heath-Heckman has received a $1.9 million grant to support her research studying the bacteria animals like squid and newts use to protect themselves.

NewsStudy in mice uncovers new protective benefit of breast milk
An immune component of breast milk known as the complement system shapes the gut environment of infant mice in ways that make them less susceptible to certain disease-causing bacteria, according to a new study.

NewsScientists address debates on postbiotic definition with new paper
A frequent misunderstanding is why microbially-produced metabolites do not qualify as postbiotics.
-
NewsBees synthesize nutrients for the bacteria in their gut microbiome
Two teams of researchers have succeeded in demonstrating that the western honey bee synthesizes nutrients for native gut microbes.
-
NewsGut bacteria combinations protect stem cell transplantation patients from dangerous immune reactions
Researchers have shown that graft versus host disease (GvHD) is less common when certain microbes are present in the gut. In the future, it may be possible to deliberately bring about this protective composition of the microbiome.
-
NewsResearchers identify why cancer immunotherapy can cause colitis
Studies in mice reveal the mechanism that induces this severe side effect and point to a solution that kills the cancer without causing gastrointestinal issues.

NewsMolecular link IDed between gut bacteria and excitatory brain signaling in C. elegans
A new study establishes a molecular link between specific B12-producing bacteria in the gut of the roundworm C. elegans and the production of acetylcholine, a neurotransmitter important to memory and cognitive function.
-
NewsStudy shines light on resourceful ways bacteria thrive in the human gut
A survey of bacterial genomes highlights the arsenal of enzymes microbes use to produce energy in the oxygen-poor environment of the gut.

NewsConsuming fermented food natto suppresses arteriosclerosis
A study shows that the intake of natto alters the composition of intestinal microflora in a mouse model, regulating the production of cytokines and chemokines associated with arteriosclerosis.

NewsA high-fat diet could make you vulnerable to harmful microbes, including Covid
A new study demonstrates that high-fat diets negatively impact genes linked not only to obesity, colon cancer and irritable bowels, but also to the immune system, brain function, and potentially COVID-19 risk.

NewsStudy reveals the relationship of gut microbiome to children’s brain development and function
Emerging evidence implicates the gut microbiome in cognitive outcomes and neurodevelopmental disorders, but the influence of gut microbial metabolism on typical neurodevelopment has not been explored in detail.

NewsMicrobiome changes in body linked to kidney stone formation
A new study has found changes in the microbiome in multiple locations in the body are linked to the formation of kidney stones.
-
NewsNew weapon against the super tough C diff bacteria shows promise
A researcher has demonstrated that a newer generation tetracycline antibiotic, Omadacycline, may be a promising tool in combating the resilient bacteria Clostridioides difficile (C diff), which causes an infection often picked up in hospitals.
-
NewsGiant bacterium uses unique processes to power itself
Scientists have for the first time described the full genome of one species of the Epulopiscium family of giant bacteria, which they’ve named Epulopiscium viviparus.
-
NewsKeto diet protects against epileptic seizures by changing gut microbiome
Researchers have demonstrated that the changes the high-fat, low-carbohydrate ketogenic diet causes in the human gut microbiome can confer protection against seizures in mice.
-
NewsSingle-celled protists in the guts of animals thrive without the ‘powerhouse of the cell’
Almost all eukaryotic organisms, from plants and animals to fungi, can’t survive without mitochondria – the ’powerhouses of the cell’, which generate chemical energy using oxygen. Termites However, a new study by Lukáš Novák and Vladimír Hampl of Charles University, published in the journal PLOS Genetics, finds ...

NewsNew research lays groundwork for personalized dietary supplements
Researchers used fluorescence-labeled inulin-grafted nanoparticles to track the interaction of inulin with gut bacteria - when incubated with human stool samples, a wider range of gut bacteria thatn previously assumed were found to bind to inulin.
