Researchers have revealed the existence of a new quorum-sensing molecule that increases the virulence of the pathogenic bacterium Pseudomonas aeruginosa.

Chemicals made by gut bacteria could be used to produce drugs that keep us healthier in old age, scientists believe.

A one-week dose of a probiotic isolated from a healthy infant’s diaper lowered rates of deadly sepsis in babies by 40 percent, researchers report.

In its attempt to fight a serious bacterial infection, caused by listeria, for example, the immune system can become so over-activated that the resulting inflammatory response and its consequences can quickly lead to death. Scientists have now demonstrated in an animal model that such an excessive response by the immune system can be modulated by targeted manipulation of the sugar metabolism to produce an immune response that efficiently eliminates the pathogens without causing any harmful secondary reactions.

A class of chemicals made by intestinal bacteria, known as indoles, help worms, flies and mice maintain mobility and resilience for more of their lifespans, scientists have discovered.

Scientists are working toward a better understand whether cyanobacteria can be grown for biofuels on a large scale.

Gut microbes have been in the news lately. Recent studies show they can influence human health, behavior, and certain neurological disorders, such as autism. But just how do they communicate with the brain? Results from a new study suggest a pathway of communication between certain gut bacteria and brain metabolites, by way of a compound in the blood known as cortisol. And unexpectedly, the finding provides a potential mechanism to explain the characteristics of autism.
