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 ...

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

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 ...

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.

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.

Gram-positive bacteria show blue or purple after Gram-staining in a laboratory test. They have thick cell walls. Gram-negative bacteria show pink or red on staining and have thin walls.
