Endotoxin, a toxic chemical found in bacteria, makes up only 0.0001% of PM2.5 fine particles but packs a serious punch when it comes to its bioactivity. Gram-negative bacteria pose a significant ...

Scientists report that they now know how to build a molecular Trojan horse that can penetrate gram-negative bacteria, solving a problem that for decades has stalled the development of effective new ...

The Infectious Diseases Pathology Branch at the United States Centers for Disease Control and Prevention receives tissues from cases that are referred, because no pathogen was found but an infectious ...

There are many ways of classifying bacteria. One method is based on the cell membrane. In 1884, a bacteriologist named Christian Gram created a test that could determine if a bacterium had a thick, ...

Gram staining is a type of differential staining used to distinguish between Gram positive and Gram negative bacterial groups, based on inherent differences in their cell wall constituents. Stains ...
