Most species of bacteria can be broadly divided into two groups, known as gram-positive and gram-negative. These categories ...

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 ...

Infectious bacteria are growing increasingly resistant to drugs, which is becoming a serious threat to public health worldwide. Bacteria can be classified based on various characteristics, such as by ...

Gram-positive bacteria have thicker cell walls that retain the purple color from Gram stain, which can quickly differentiate cell types based on the width of their cell walls.

Researchers from the National University of Singapore (NUS) have solved a 60-year-old mystery in bacterial cell envelope ...

The dye gets into the cells’ peptidoglycan layer (gray), tinting it purple. That layer is thicker in gram-positive cells (top) than in gram-negative bacteria (bottom).

All the latest science news on gram-negative bacteria from Phys.org. Find the latest news, advancements, and breakthroughs.

A team of Princeton researchers has identified a compound that can kill both Gram-positive and Gram-negative bacteria via two independent mechanisms, as well as resist antibiotic resistance.

Gram-negative bacteria are especially difficult to treat because they have strong defense systems—tough cell walls that keep most antibiotics out and pumps that efficiently remove those ...
