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 ...

Many gram-negative bacteria are pathogenic, like Pseudomonas aeruginosa, and E. coli, and can evade antibiotics. Researchers have wanted to know more about disrupting the gram-negative cell wall ...

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

When people take antibiotics, some of the dose is excreted with urine and feces and ends up in our wastewater. The presence ...

Gram positive vs gram negative Gram positive bacteria are surrounded by a single thick peptidoglycan cell wall and are therefore termed monoderms. Gram negative bacteria have a much thinner ...

Now, researchers at UConn Health have discovered how gram-negative bacteria trigger such a dangerous reaction from our body. Bacteria are not supposed to be in the bloodstream.

Find out the differences between gram-positive bacillus and gram-negative bacillus and how they may affect health.

Gram-negative cells, such as E. coli, have a thin peptidoglycan layer sandwiched between a porous outer membrane and an inner membrane.

Differences between gram-positive and gram-negative bacteria All bacteria have a cell wall composed of mesh-like strands of a big molecule called peptidoglycan, which surrounds the cell membrane.
