Older siblings may influence a child’s microbiota

The findings of a new research suggest that during the early maturation, the microbiota would be more likely to be influenced by other microbiotas on a not-too-distant level of maturity.

Gut microbes may regulate host physiology by metabolizing vitamin A

The results of a new research done in mice suggest that gut bacteria can regulate host physiology by metabolizing vitamin A.

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.
