A new study published in Nature today has identified a potential Achilles heel in the protective layers surrounding Gram-negative bacteria that could aid in the development of next-generation ...

The process that allows bacteria to expand and grow while maintaining the strength of the cell walls has been identified as offering a potential new target for antibiotics. A new study published in ...

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 ...

After more than 130 years, scientists may finally have figured out how a common laboratory method for identifying bacteria works. Invented by Hans Christian Gram in 1884 and thus known as the gram ...

With delicate hues of purple and pink, a lab technique called gram staining has reliably characterized bacteria for more than a century. Yet many scientists are mistaken about why the vivid method ...

Researchers have developed a new antibiotic that reduced or eliminated drug-resistant bacterial infections in mouse models of acute pneumonia and sepsis, while sparing healthy microbes in the mouse ...

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, ...

Researchers have developed a new antibiotic that reduced or eliminated drug-resistant bacterial infections in mouse models of acute pneumonia and sepsis while sparing healthy microbes in the mouse gut ...
