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.

Deadly fungus uses unexpected system to control its virulence

A research team led by UC San Francisco scientists has discovered a cellular signaling system that regulates the virulence of Cryptococcus neoformans, a fungus that has been estimated to cause nearly a million cases of meningitis ...

Chemists find new compounds to curb staph infection

(Phys.org) —In an age when microbial pathogens are growing increasingly resistant to the conventional antibiotics used to tamp down infection, a team of Wisconsin scientists has synthesized a potent new class of compounds ...

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 ...

Quorum sensing: Researchers examine bacteria communication

European researchers at Linköping University in Sweden are showing how bacteria control processes in human cells through a process called quorum sensing. This phenomenon is where bacteria talk to each other via molecules ...

Solving streptide from structure to biosynthesis

Bacteria speak to one another using peptide signals in a soundless language known as quorum sensing. In a step towards translating bacterial communications, researchers at Princeton University have revealed the structure ...

New mechanisms of 'social networking' in bacteria

Bacteria have traditionally been viewed as solitary organisms that "hang out on their own," says molecular biologist Kevin Griffith of the University of Massachusetts Amherst. However, scientists now realize that in fact, ...
