New UCLA-led research suggests certain gut bacteria—including one that is essential for a healthy gut microbiome—differ between people who go on to acquire HIV infection compared to those who have not ...

Most species of bacteria can be broadly divided into two groups, known as gram-positive and gram-negative. These categories reflect big differences in the microbes' biology, and they also dictate how ...

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 ...

In a recent study published in the journal Nature, researchers in the United States of America designed and discovered lolamicin, a selective antibiotic that targets the lipoprotein transport system ...

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 ...

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 ...

A team of researchers at the University of California, Los Angeles (UCLA) has introduced a virtual Gram staining technique that could transform how microbiologists stain and classify bacteria. This ...

Nearly 12,000 people in the U.K. who received a first dose of the MenB vaccine will now be offered a second shot starting next week, after a deadly meningitis outbreak linked to a university in Kent.
