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.

Both gram-negative and gram-positive bacteria use quorum sensing. Generally, gram-negative bacteria employ acylated homoserine lactones as autoinducers, which diffuse into the environment passively.

In fact, the authors noted, Gram-negative bacteria represent four of the top six pathogens causing antibiotic-associated deaths, with some studies indicating that 75% of deaths from drug-resistant ...

Zosurabalpin is able to destroy Gram-negative bacteria by jamming LPS molecules inside the bacteria, weakening its membrane. It is the first of its class of antibiotics, and the first new class of ...

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 notoriously difficult to drug because of their tough outer membranes. Existing antibiotics have a hard time getting through, ...

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 ...
