DNA islands effective as 'anti-bacterial drones'

Genomic "islands" that evolved from viruses can be converted into "drones" that disable Staphylococcus aureus, bacteria that are often resistant to antibiotics and pose a threat to safe hospital care, a new study finds.

New staph virulence factor

Staphylococcus aureus (staph) is a leading cause of hospital-acquired infections and an increasing threat to public health. Enzymes called serine hydrolases modulate host-pathogen interactions, but little is known about this ...

How pathogenic bacteria prepare a sticky adhesion protein

Researchers at Harvard Medical School, the University of California, San Francisco, and the University of Georgia have described how the protein that allows strep and staph bacteria to stick to human cells is prepared and ...

Hibernating ribosomes help bacteria survive

In the second of two high-profile articles published in recent weeks, Saint Louis University scientist Mee-Ngan F. Yap, Ph.D., in collaboration with the laboratories of 2009 Nobel laureate in chemistry Ada Yonath at the Weizmann ...

Chemical coatings boss around bacteria, in the bugs' own language

Princeton researchers have developed a way to place onto surfaces special coatings that chemically "communicate" with bacteria, telling them what to do. The coatings, which could be useful in inhibiting or promoting bacterial ...

Distinguishing deadly Staph bacteria from harmless strains

Staphylococcus aureus bacteria are the leading cause of skin, soft tissue and several other types of infections. Staph is also a global public threat due to the rapid rise of antibiotic-resistant strains, including methicillin-resistant ...
