Lactobacilli may help to treat acne

Researchers have found that Lactobacilli could be used to treat common acne lesions, reducing the need for topical antibiotics.

Large study links gut microbes to depression

Researchers have found that some gut microbes may be connected to depression, thus highlighting that the intricate relationship between humans and their microbiota could have important health implications.

How new microorganisms become part of the gut microbiota

Researchers have now found that the interactions between existing gut commensals sets the odds for whether new microbes are acquired.

Some gut microbes may lead to depression by degrading male sex hormone

Researchers have found that testosterone-degrading enzymes expressed by gut microbes are associated with depressive symptoms.

How gut microbes help squirrels stave off muscle loss

Researchers have found that microbes in the gut of ground squirrels recycle a waste product into building blocks to make proteins, helping the animals to survive a long winter without…

Akkermansia muciniphila can be a biomarker of response to cancer therapy, study suggests

Akkermansia can be used as a biomarker to identify who is likely to respond to treatment with immune checkpoint inhibitors. A new study published in Nature Medicine claims

New technology allows researchers to identify ‘hidden’ microbes

By combining HiFi with advanced algorithms, the researchers identified the genomes of 428 microbial species with more than 90% completeness.

Early viral encounters may affect airway microbiota, lead to recurrent respiratory infections

Early viral encounters are associated with disadvantageous immune and microbiota profiles, as well as recurrent respiratory infections. A new study published in Nature Microbiology claims.

Diet may affect how gut microbes evolve

Periodic variations in diet can be important to avoid the fixation of specific mutations and maintain a high genetic diversity in the microbiota.

Gut microbes help wild pandas fatten up while eating bamboo

Seasonal changes in the gut microbiota can influence growth in wild pandas and may explain how these animals compensate for the lack of nutrients in leaf-eating season. A new study…
