New strategy to protect healthy gut microbes from antibiotics

Gut microbes promote human health by fighting off pathogens, but they also contribute to diseases such as diabetes and cancer. A study published March 19th by Cell Reports reveals a potential strategy for tipping the balance ...

Variety in diet can hamper microbial diversity in the gut

Scientists from The University of Texas at Austin and five other institutions have discovered that the more diverse the diet of a fish, the less diverse are the microbes living in its gut. If the effect is confirmed in humans, ...

Antibiotics have long-term impacts on gut flora

Short courses of antibiotics can leave normal gut bacteria harbouring antibiotic resistance genes for up to two years after treatment, say scientists writing in the latest issue of Microbiology, published on 3 November.

Exploring the role of gut bacteria in digestion

They congregate in the environments that suit them best; some prefer the dry, desert-like conditions of our forearms while others thrive in the Amazon-style humidity of our feet.

Revealing the metabolic activity of microbial communities

Microbial communities are performing important functions all around us - from the earth in our flowerpots to the human gut. Now researchers have developed a method for studying the metabolic functions of microbial communities ...

Bacterial strain diversity in the gut

What drives bacterial strain diversity in the gut? Although there are a number of possible explanations, a recent opinion piece published in TRENDs in Microbiology by Dr Pauline Scanlan, a Royal Society – Science Foundation ...

Microbe artwork shows the limits of antibiotics

An Oxford University research fellow has been creating art using bacteria found in the human gut and harvested from faecal samples. But while the striking colours and plant like shapes may look beautiful, they also illustrate ...
