Specific prebiotics may influence gut microbes in ways that prevent obesity

New research in mice suggests that two MACs, L-arabinose and sucrose, have specific effects on gut microbes that may prevent diet-induced obesity.

How gut bacteria may evolve to become harmful

The findings of a new research show that gut bacteria can become harmful over time by gaining the ability to escape the intestine and persist in other organs where they…

Bacterial signatures in gut and airway may be biomarker for COVID-19 severity

The findings of a new research suggest that changes in the microbial composition of people with COVID-19 could be used as a biomarker of invasion of lung pathogens and dysbiosis…

IgA antibodies bind to specific gut bacteria in mice

The findings of a new research may inform strategies for treating intestinal diseases by targeting pathogens without killing beneficial gut bacteria.

Could “rejuvenating” the microbiota bring health benefits?

Researchers at Harvard Medical School propose to “rejuvenate” a person’s microbiota by collecting stool samples for future treatment of diseases that could be managed with fecal microbial transplantation (FMT).

Some gut bacteria produce key lipids involved in cell signaling

The findings of a recent study suggest that the production of inositol lipids is common in Bacteroidetes and other gut-associated bacteria, and it may be a means of cross-kingdom communication.

Some viruses alter the skin microbiota of their host to attract mosquitoes

The findings of a recent study suggest that dengue and Zika viruses are able to change their host’s odor by altering the skin microbiota.

Structures of microbial enzymes hint at how these proteins recognize their targets

New research offers insights into how human gut bacteria recognize sulfated glycans. The findings could help to develop interventions for diseases where sulfated glycan metabolism is altered.

Microbiotas of Hadza infants differ from those of infants living in industrialized areas

New research shows that microbiota diversity appears early in infants from nonindustrial populations and could be traced back to their mothers as well as to the local environment. 

Probiotics may help to treat depression

The findings of a small clinical trial suggest that probiotic treatment could be used in combination with antidepressant medication to treat clinical depression.
