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 biology, defining the primary function of an important protein complex ...

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

Importantly, the antibiotic also appeared to leave commensal bacteria alone, since many are gram-positive bacteria that don’t have the Lol complex that lolamicin exploits.

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 ...

The cell membrane in gram-positive bacteria is roughly 20 times thicker than that of gram-negative bacteria but can be easily breached.
