The results were published on June 25 in Scientific Reports. This finding is a new concept: both Gram-positive and -negative bacteria are involved in the progression of periodontal bone loss.

Gram-negative bacteria pose a significant threat to global health due to their high resistance to antibiotics compared to ...

The team demonstrated the technology's effectiveness using bacterial samples containing both Gram-positive and Gram-negative bacteria (Listeria innocua and Escherichia coli).

Gram-positive and gram-negative bacteria differ in the composition of their cell walls. Gram-negative bacteria have a double layer of protection, making them more difficult to kill, Muñoz said.

Pathogenic bacteria can be classified as either Gram-positive or Gram-negative, after the scientist Hans Christian Gram, who developed a staining technique that can distinguish between them.

This means that gram-negative bacteria can be harder to treat than gram-positive bacteria. This type of bacteria gets its name from the gram stain test.

Most of Gram-positive isolates from urinary tract (100%), respiratory tract (89.7%), and bloodstream infections (BSIs; 65.5%) were obtained from leukemic patients. All Gram-positive isolates from skin ...

On the other hand, gram-negative bacteria’s cell membrane is tough to break through. This makes gram-positive bacteria more vulnerable to antibiotics and other antibacterial actions.

In a recent study, researchers demonstrated that a novel compound could treat flesh-eating Gram-positive bacterial infections in mice, potentially offering a new class of antibiotics. Researchers at ...
