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 ...

In natural environments, bacteria rarely live as free-swimming cells but are attached to surfaces as biofilms in medical devices, mobile phones or human tissue. The bacterial behavior, how they attach ...

A new drug conjugate tricks Gram-negative bacteria into succumbing to an antibiotic that usually works only against Gram-positive bacteria. Gram-negative bacterial infections are tough to treat ...

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, ...

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 ...

More and more bacterial pathogens of infectious diseases become resistant to customary antibiotics. Typical hospital germs such as Escherichia coli and Klebsiella pneumoniae have become resistant to ...

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 ...

Evotec AGEVTCY announced that it has extended its existing collaboration agreement with Spero Therapeutics for the development of new and ground-breaking therapeutics for Gram-negative bacteria. The ...

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 ...
