Most species of bacteria can be broadly divided into two groups, known as gram-positive and gram-negative. These categories ...

Researchers from the National University of Singapore (NUS) have solved a 60-year-old mystery in bacterial cell envelope ...

Gram-positive and gram-negative bacteria differ in the composition of their cell walls. Gram-negative bacteria have a double layer of protection, making them more difficult to kill, Muñoz said.

Remnants of everything that humans ingest ends up in waste water, including medications that people may be taking, like ...

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 ...

Gram-negative bacteria are especially difficult to treat because they have strong defense systems—tough cell walls that keep most antibiotics out and pumps that efficiently remove those ...

In contrast, gram-positive bacteria typically use processed oligopeptides, which must be actively secreted through their cell wall. 1,2 What Is Interspecies Quorum Sensing? Intraspecies quorum sensing ...

But a new antibiotic from Swiss pharmaceutical company Roche could change the future of how we treat Gram-negative bacteria. Roche announced on Monday that its antibiotic zosurabalpin will enter ...

This characteristic can also arise in different ways. For example, there are some types of bacteria, which are classified as Gram-negative based on their cell membrane, that can increase the activity ...
