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…

Different acne bacteria live on our skin — but not within the same pore

In order to manipulate the human microbiotas to help treat disease, scientists have to gather information about the identities of microbes and their location and arrangement in different body sites.

A high-fiber diet may improve melanoma patients’ response to immunotherapy. A new study published in Science claims.

Antibiotics may fuel resistance in skin microbes

Antibiotics can alter the skin microbiota and lead to the emergence of antibiotic resistance. A new study published in Science Translational Medicine.

How a gut microbe may suppress colorectal cancer growth

Lactobacillus reuteri can protect against colorectal cancer through reuterin, one of its metabolites. A new study published in Cencer Cell claims

How the human microbiota can influence respiratory health

Profiling the bacteria and viruses residing in the human body could help to diagnose different pathogens and develop new targeted interventions.

Excess food may reduce male fertility by altering gut microbiota, vitamin A metabolism

A high-fat diet induces gut microbial alterations and leads to male infertility. A new study published in Gut claims.

Some gut-dwelling bacteria are associated with gastric cancer and liver metastasis

Alterations in the levels of gut-dwelling Streptococcus microbes are associated with the development of gastric cancer and the associated liver metastases.

During puberty, the gut microbiota becomes more adult-like — but only in girls

Some gut microbes can affect the timing of puberty by regulating the levels of sex hormones in a sex-dependent manner. A new study published in Scientific Reports claims.

A mother’s gut bacteria drive intestinal inflammation in mice with autism-like traits

Autistic people who experience inflammatory problems may have been exposed to inflammation in the maternal womb. A new study published in Immunity claims.

After quitting smoke, changes in the gut microbiota may lead to weight gain

A new study (Nature) helps to understand why people who stop smoking often gain weight.

New insights into how commonly used drugs affect the gut microbiota

The impact of medications on the gut microbiota is greater than previously thought. A new research published in Nature claims.
