Synthetic biologists redesign the way bacteria 'talk' to each other

Bioengineers at the University of California San Diego have redesigned how harmless E. coli bacteria "talk" to each other. The new genetic circuit could become a useful new tool for synthetic biologists who, as a field, are ...

Toxin-spewing bacteria decoded

Scientists at Emory University School of Medicine have identified a central regulator of toxin production in the bacterium C. difficile, the most common cause of healthcare-associated infections in the United States. C. difficile ...

How antibiotics spread resistance

Bacteria can become insensitive to antibiotics by picking up resistance genes from the environment. Unfortunately for patients, the stress response induced by antibiotics activates competence in microorganisms, the ability ...

New compound may stop bacteria from causing sickness

A study published in the Journal of Biological Chemistry is the first to describe a signaling pathway that affects communication—a process called quorum sensing—between Streptococcus bacteria cells.

Researchers find an alternative mode of bacterial quorum sensing

Whether growing in a puddle of dirty water or inside the human body, large groups of bacteria must coordinate their behavior to perform essential tasks that they would not be able to carry out individually. Bacteria achieve ...
