Some gut microbes help the body absorb more dietary fat, which means their host takes in more calories from the same amount of food.
“This study is the first to demonstrate that microbes can promote the absorption of dietary fats in the intestine and their subsequent metabolism in the body,” ... Read More
Bacteria talk to each other using N-acylhomoserine lactones (AHLs) as quorum sensing (QS) signals. This signaling allows the bacteria to control gene expression of virulence factors and biofilms once a critical density has been achieved. This phenomenon, quorum sensing, is important when an infe... Read More
Physicians should pay attention to their "gut feeling" that something may be seriously wrong when assessing a child with an infectious disease -- even if the clinical appearance is reassuring -- an observational study suggested.
