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 ...

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 ...

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 ...

Researchers have discovered how antibiotic-resistant bacteria construct their defense system -- a finding that could lead to new treatments for currently untreatable infections. Superbugs, also known ...

Scientists have captured images of polymyxins, a type of antibiotic, disrupting and infiltrating the membranes of ...

In the search for new antibiotics to combat growing drug resistance, Gram-negative bacteria present a daunting challenge. These microbes sport a cell wall and a tight double membrane that create an ...

A team led by Paul Hergenrother at the University of Illinois Urbana-Champaign has discovered a new antibiotic that exclusively targets gram-negative bacteria and avoids wiping out the ecosystem of ...

With this in mind, microbiologist professor Brenda Wilson of the University of Illinois Urbana-Champaign, has shared what you ...

Gram-positive bacteria show blue or purple after Gram-staining in a laboratory test. They have thick cell walls. Gram-negative bacteria show pink or red on staining and have thin walls. They release ...
