Bacteria with thick peptidoglycan are called gram positive. If the peptidoglycan layer is thin, it's classified as gram negative. A gram-positive bacillus doesn't have an outer cell wall beyond ...

The star of the story is saarvienin A, a brand-new glycopeptide antibiotic produced by an unusual strain of Amycolatopsis, a ...

Now, researchers from Northeastern University and NovoBiotic Pharmaceuticals and their colleagues have identified a new Gram-positive bacteria-targeting antibiotic from a soil sample collected in ...

Researchers have discovered saarvienin A, a novel glycopeptide antibiotic from a rare earth mine bacterium. It shows potent ...

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 ...

Older people tend to carry more Gram-negative bacteria in their guts; the cell walls of Gram-negative and -positive bacteria are different. The increase in Gram-negative bacteria in older people leads ...

Not all cases of non-HACEK Gram-negative bacterial endocarditis necessarily require surgical intervention. Indications for surgical intervention in patients with Gram-negative endocarditis are ...
