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 how ...

Blacksmith Medicines, Inc. (Blacksmith), a leading biopharma dedicated to discovering and developing therapeutics targeting metalloenzymes, today announced that Professor Seth Cohen, Ph.D., the ...

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 ...

These gram-positive bacteria are typically found in human and animal intestines. Bacteria are of two types – gram-positive and gram-negative – based on their characteristics.

Gram-negative bacteria have an outer membrane that differs from gram-positive bacteria. This membrane is difficult for antibiotics to pass through.

A bacteria can either be Gram-negative or Gram-positive. These terms come from the Gram-staining test developed by Hans Christian Gram in 1884, which involves applying a purple stain to bacteria.

Nisin treatment also increased the relative abundance of Gram-negative bacteria such as E. coli and reduced the abundance of Lactobacillus and other Gram-positive bacteria.

Most antibiotics, whether Gram-positive-only or broad-spectrum, harm gut commensals and cause dysbiosis. The impact of Gram-negative-only antibiotics on the microbiome is unclear due to the ...
