Escherichia coli bacteria are known to live in the gut, and they can also sicken people if they contaminate food that gets eaten. These bacteria can easily survive in many different environments, ...

Bad bacteria can survive in extremely hostile environments — including inside the highly acidic human stomach — thanks to their ability to sequester toxins into tiny compartments. In a new study, ...

Fat bacteria? Skinny bacteria? From our perspective on high, they all seem to be about the same size. In fact, they are. Precisely why has been an open question, according to Rice University chemist ...

Widespread antibiotic use is largely to blame for the emergence of antibiotic-resistant bacteria, which is currently one of the biggest threats to global health. Not only does antibiotic resistance ...

Scientists have found that Bacteroides thetaiotaomicron, a key gut microbe, changes its size and shape in response to its environment. Each different microbe form is linked to specific genetic ...

A simple theoretical model seeks to explain why bacteria remain roughly the same size and shape. The work by chemists could offer new insight into diseases, including cancer. Fat bacteria? Skinny ...

Genetic differences in the immune system shape the collections of bacteria that colonize the digestive system, according to new research by scientists at the University of Chicago. In carefully ...

Harvard immunologist Dennis Kasper and his colleagues have found that tiny changes in gut bacteria can flip the immune system from calm to inflamed, even when the microbes look harmless. Their work, ...

Unaffected siblings showed the richest and most diverse gut microbiome Beneficial bacteria like Anaerostipes were linked to better social and emotional outcomes Gut imbalance was associated with ...
