Artificial bacterial transformation is a laboratory technique scientists use to introduce foreign DNA into bacterial cells. There are two main methods by which this is achieved: Gram positive and Gram ...

Gram staining is one way scientists can identify bacteria. Gram-positive bacteria, such as Staphylococcus, appear blue or purple under a microscope when scientists apply a stain. Conversely ...

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 ...

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 ...

A research team affiliated with UNIST has unveiled a novel extracorporeal blood purification technology that captures and ...

Researchers have developed a compound that is effective against common bacteria that can lead to rare, dangerous illnesses. Researchers at Washington University School of Medicine in St. Louis ...

The research is published Aug. 2 in Science Advances. The compound targets gram-positive bacteria, which can cause drug-resistant staph infections, toxic shock syndrome and other illnesses that ...

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.
