Two large studies link specific gut bacteria to depression

The findings of a new research support the link between gut microbes and depression, and suggest that the gut microbiota can be a target for future therapies.

Japanese gut metagenomes show microbial features associated with diet and disease

The findings of a japanese research suggest that several viruses are linked to specific populations and diseases.

Gut microbes may mediate beneficial effects of low-carb diet on irritable bowel syndrome

Researchers have found that a diet low in fermentable carbohydrates can alter the human microbiota in ways that influence the expression of genes involved in inflammation and intestinal integrity.

How the tumor microbiota may reduce the efficacy of cancer drugs

A recent study confirms that 5-FU exerts part of its anti-cancer effects through inhibiting the growth of F. nucleatum, the commensal associated with colorectal cancer progression.

A closer look at the microbiota of the small intestine

A recent study confirms that ileum and colon have a distinct microbiota: unlike the bacterial composition of the colon, the ileum is subject to frequent fluctuations.

Gut bacteria influence response to cocaine in mice

The findings of a new research may help to inform therapies to modulate brain circuits that are involved in substance use disorders.

COVID-19 may disrupt gut microbiota to increase risk for other infections

Microbiota alterations in COVID-19 patients appeared to be associated with secondary infections of the blood by gut bacteria: four cases of positive blood cultures of Staphylococcus species were identified.

DNA-damaging microbial metabolites found in people with inflammatory bowel disease

The findings of a recent study suggest that DNA damage-inducing microbial metabolites such as indolimines play a role in the development of colorectal cancer.

Some gut bacteria may trigger autoimmunity in rheumatoid arthritis

The findings of a recent study suggest that a specific strain of Subdoligranulum can drive the production of autoantibodies in rheumatoid arthritis.

Nicotine-degrading microbes may protect against smoking-related liver disease

Scientists identified a bacterium, Bacteroides xylanisolvens, that reduced gut nicotine concentrations in mice exposed to nicotine as well as the severity of NAFLD.

Some gut bacteria can curb atherosclerosis in mice

A recent study provides evidence for the beneficial effects of GMD and the gut commensal bacterium P. merdae against obesity-related atherosclerosis.

Periodontitis may be linked to Alzheimer’s disease

Periodontitis might be associated with cognitive decline, suggesting a possible etiopathologic role in Alzheimer's disease.

Hot topics at Probiota Asia and Growth Asia 2022: check it here if you missed it

Microbiota-derived ethanol may contribute to nonalcoholic fatty liver disease

The findings of a new research suggest that, in some people, microbial ethanol can contribute to the development of NAFLD.

Tumor-microbiota interactions may help to identify new treatments for pancreatic cancer

The findings of a new research may help to develop improved diagnostic or treatment approaches for pancreatic cancer.

L. rhamnosus GG increases Bifidobacteria and reduces inflammation in children with cystic fibrosis, study says

A supplement of LGG would seem to favour the proliferation of Bifidobacterium and the improvement of clinical and immunological response to childhood cystic fibrosis.

How microbiotas interact after fecal transplantation

Researchers found that the microbiota of the recipient, rather than that of the donor, determines the microbial mix resulting from a fecal transplant.

Studies reveal the fungal communities associated with tumors

New studies provide evidence that there may be fungi within tumors and could also help to diagnose certain types of cancer or predicting their course.

COVID-19 in children: nasal microbiota as a possible ‘shield’ protection

Moraxella may be involved in protecting children from COVID-19 infections through its action on amino acid and lipid metabolism in the upper respiratory tract.

Engraftment levels may determine success of microbiota transplant

The findings of a new research could help to optimize fecal microbiota transplantation (FMT) protocols and identify the most suitable donors for transplantation.
