Researchers have revealed how a common bacterium, Enterococcus faecalis (E. faecalis), releases lactic acid to acidify its surroundings and suppress the immune-cell signal needed to start a proper ...

Acute graft-versus-host disease occurs when donor immune cells attack the recipient's tissues after an allogeneic hematopoietic stem cell transplantation (allo-HCT). Researchers recently identified a ...

A new study led by a research team from Massachusetts Eye and Ear and Harvard Medical School describes how bacteria adapted to the modern hospital environment and repeatedly cause antibiotic-resistant ...

A typical gut bacterium that can spread through the body and cause a serious infection resists natural immune defenses and antibiotics by enhancing its protective outer layer, known as the cell ...

A huge tool-kit of genes allows a rogue form of a normally harmless gut bacterium to cause life-threatening infections. The finding could lead to new ways to predict, prevent or treat these infections ...

In a new study, researchers have uncovered how cytolysins from Enterococcus faecalis destroys bacterial and mammalian cells. Although Enterococcus faecalis is usually an innocuous member of the ...

Allogeneic hematopoietic-cell transplantation is a mainstay of treatment for hematologic cancers, and the gut microbiota — the collection of archaea, bacteria, fungi, protists, and viruses that reside ...

For three decades, the deadly bacteria sat in cold storage. Normally, Enterococcus faecalis lives harmlessly in the human gut. One particular strain, however, caused a series of strangely persistent ...
