Researchers have developed a new antibiotic that reduced or eliminated drug-resistant bacterial infections in mouse models of acute pneumonia and sepsis, while sparing healthy microbes in the mouse ...

A team led by Paul Hergenrother at the University of Illinois Urbana-Champaign has discovered a new antibiotic that exclusively targets gram-negative bacteria and avoids wiping out the ecosystem of ...

Gram-positive bacteria show blue or purple after Gram-staining in a laboratory test. They have thick cell walls. Gram-negative bacteria show pink or red on staining and have thin walls. They release ...

Mouths are filthy, harboring the second largest microbiome of the human body. Some bacteria can help break down food, among other responsibilities; other bacteria can travel into the mouth on food, ...

The Tol-Pal complex maintains bacterial outer membrane (OM) stability by regulating lipid homeostasis. (Left) In Gram-negative bacteria, the OM acts as a protective barrier, blocking entry of harmful ...

Scientists from Cornell University, University of California, San Francisco (UCSF), and elsewhere have found that a surplus of membrane proteins may help bacteria survive antibiotic exposure. These ...
