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, ...

Lead antibacterial compound against a novel target in Gram-negative bacteria validated in infection modelsProgressing a ...

The antibiotics, called polymyxins, were observed forcing the armored membranes around Escherichia coli bacterial cells to grow bumps and bulges. The bacteria then shed their outer membranes, leaving ...

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 ...

Mouths are filthy, harboring the second largest microbiome of the human body. Some bacteria can help break down food, among other responsibilities; other bacteria can travel into the mouth on food, ...

Scientists from Cornell University, University of California, San Francisco (UCSF), and elsewhere have found that a surplus of membrane proteins may help bacteria survive antibiotic exposure. These ...

Gram-negative meningitis is a form of meningitis. The term gram-negative refers to a way of differentiating bacteria. This type of bacteria is typically resistant to drugs and most available ...

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 ...
