Gram-negative bacteria are bacteria that, unlike gram-positive bacteria, do not retain the crystal violet stain used in the Gram staining method of bacterial...

The Gram stain is used by microbiologists to place bacteria into two main categories, gram-positive (+) and gram-negative (−). Gram-positive bacteria have...

and gram-negative bacteria. It may also be used to diagnose a fungal infection. The name comes from the Danish bacteriologist Hans Christian Gram, who...

resistant Gram-negative bacteria (MDRGN bacteria) are a type of Gram-negative bacteria with resistance to multiple antibiotics. They can cause bacteria infections...

for components of the outermost membrane of the cell envelope of gram-negative bacteria, such as E. coli and Salmonella with a common structural architecture...

family Moraxellaceae. This genus, Moraxellaceae, comprises gram-negative coccobacilli bacteria: Moraxella lacunata, M. atlantae, M. boevrei, M. bovis, M...

of the outer membrane of the cell wall of gram-negative bacteria. Endotoxins are released when the bacteria lyses, which is why after antibiotic treatment...

experimental antibiotic compound that may be effective against Gram-negative bacteria. If it can be developed into a human-compatible form it would be...

reduced permeability in bacteria, the mechanisms are different between Gram-positive and Gram-negative bacteria. In Gram-positive bacteria, blockage of penicillin...

bacterial outer membrane called the periplasmic space in Gram-negative (more accurately "diderm") bacteria. Using cryo-electron microscopy it has been found...

inhibit Gram positive bacteria and some Gram negative bacteria; narrow-spectrum antibiotic can only kill or inhibit limited species of bacteria. Currently...

comprises the inner cell membrane and the cell wall of a bacterium. In Gram-negative bacteria an outer membrane is also included. This envelope is not present...

Atypical bacteria are bacteria that do not get colored by gram-staining but rather remain colorless: they are neither Gram-positive nor Gram-negative. These...

various diseases. The capsule—which can be found in both gram negative and gram-positive bacteria—is different from the second lipid membrane – bacterial...

Poly(ethylenimine) is also an effective permeabilizer of the outer membrane of Gram-negative bacteria. Both linear and branched polyethylenimine have been used for CO2...

Both gram-positive and gram-negative bacteria use quorum sensing, but there are some major differences in their mechanisms. For the bacteria to use...

cases of septic shock are caused by gram-positive bacteria, followed by endotoxin-producing gram-negative bacteria, although fungal infections are an increasingly...

cytoplasmic membrane by the twin-arginine translocation pathway (Tat). Gram-negative bacteria have two membranes, thus making secretion topologically more complex...

culture medium for bacteria. It is designed to selectively isolate gram-negative and enteric (normally found in the intestinal tract) bacteria and differentiate...

bacterial cell walls, those of Gram-positive bacteria and those of Gram-negative bacteria, which are differentiated by their Gram staining characteristics....

types of inclusions such as gas vesicles and storage granules. In gram-negative bacteria proteins may be incorporated into the plasma membrane, the outer...

threshold triggers altered gene expression. Performed by both Gram-negative and Gram-positive bacteria, detection of autoinducers allows them to sense one another...

component of an endotoxin held responsible for the toxicity of gram-negative bacteria. It is the innermost of the three regions of the lipopolysaccharide...

walls of gram-negative bacteria and is recognized by TLR2, which is usually in a heterodimer of with TLR1 or TLR6. Lipoteichoic acid (LTA) from gram-positive...

broad spectrum activity against gram-negative bacteria and somewhat narrower activity against gram-positive bacteria. For empiric therapy (treatment of...

bacteriocins found in the Gram-negative E. coli. Similar bacteriocins (CLBs, colicin-like bacteriocins) occur in other Gram-negative bacteria. CLBs typically target...
