International travel may contribute to the spread of antibiotic resistance

A new study published in Genome Medicine suggests that international travel poses a high risk by favoring the global spread of antimicrobial resistance.

Dispersal strategies determine for how long bacteria persist in the gut

A new study published in Cell Host & Microbe illustrates how different dispersal strategies can allow bacteria to persist in the human gut.

High-fat diet is linked to changes in gut microbiota, development of antibiotic tolerance

A high-fat diet is associated with changes in the gut microbiota and microbial metabolites. These changes seem impair antibiotic efficacy.

Largest-ever survey of urban microbes finds that each city has its unique microbiota

A new study published in Cell could help to detect infection outbreaks and study the distribution of antibiotic-resistant microbes in different urban areas.

Pea flour could restore gut microbes, help malnourished children to gain weight

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

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.

Infants’ gut microbiotas harbor hundreds of antibiotic-resistance genes

A new study published in Cell Host & Microbe claims that the infant gut is home to bacteria that harbor hundreds of antibiotic-resistance genes.

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