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, ...

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, ...

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 ...

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 ...

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 ...

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 ...

Alterations to the respiratory microbiome have been identified as a predisposing factor of interstitial lung diseases (ILD). In a new study, researchers studied the influence of bacterial virulence on ...

Decision trees — an approach to predicting whether patients develop resistance to antibiotics and tailored specifically to each institution — can aid clinicians in prescribing the drug or drug ...

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 ...
