Cowpea-based foods protect the gut microbiota, helping malnourished children to grow stronger. A new study published in Cell Reports Medicine claims.

Immune cells on skin help to maintain a healthy microbiota

Immune cells called group 2 innate lymphoid cells (ILC2s) are responsible for triggering a response when bacteria and viruses breach the skin.

A newborn’s first stool could reveal risk of developing allergies

The composition of a baby’s first stool could determine whether children are likely to develop allergies and other conditions later in life.

Food dyes metabolized by gut microbes cause colitis in mice with dysregulated immune system

Specific food dyes are environmental risk factors for colitis development in conditions where IL-23 expression is dysregulated.

People at risk for rheumatoid arthritis have unique viral communities in their guts

A new study published in Cell Host & Microbe could pave the way for using phages as biomarkers for the condition of rheumatoid arthritis.

Intestinal microbes could protect against gut inflammation and colorectal cancer

The alterations in gut microbiota composition observed in mice lacking TAK1 can generate a protective immunity against colitis and colorectal cancer.

Gut microbes produce metabolites that mimic human signaling molecules

Fatty acid amides produced by Clostridia can help the bacteria to modulate their host by mimicking human signaling molecules.

Ancient feces reveal dramatic changes in the human microbiota over the past 2,000 years

The evolutionary history of the human microbiota could help to understand the role of present-day gut microbes in health and disease.

COVID-19 could have long-lasting impacts on gut microbiota composition

Several bacteria associated with human health are acquired late in childhood — albeit with different developmental dynamics.

Bacterial, viral, and fungal interactions influence inflammation and exacerbation in bronchiectasis

The Integrative Microbiomics tool could potentially delineate subtypes of bronchiectasis and other heterogeneous respiratory diseases.

Gut bacteria swap genes at much higher rates in industrialized societies

Gut bacteria from people in industrialized countries exchange genes at much higher rates than bacteria from people living in non-industrialized societies.

How changes in microbiota composition could influence human health

The microbial communities inhabiting the gut have been shown to change in ways that influence the development of disease through blood metabolites.

Breast milk molecule may help support certain gut bacteria, reduce obesity risk in newborns

A molecule in breast milk, called betaine, may lower the risk of obesity by preventing accelerated growth in newborns and supporting bacterial species.

Patients with dry eye disease have a distinct ocular microbiome that may trigger and perpetuate inflammation

Th17 cells and Treg cells, the resident ocular microbiota could potentially trigger and perpetuate inflammation in dry eye disease.

Antibiotic resistance is often spread in the gut microbiota of hospitalized people

A targeted decontamination could be a strategy to control the spreading of carbapenem-resistance plasmids both amoung patients and within patients.

How a mouth-dwelling microbe inhibits the growth of other bacteria
