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 ...

Scientists say they have developed a new type of antibiotic to treat bacteria that is resistant to most current antibiotics and kills a large percentage of people with an invasive infection. The ...

But a new antibiotic from Swiss pharmaceutical company Roche could change the future of how we treat Gram-negative bacteria. Roche announced on Monday that its antibiotic zosurabalpin will enter phase ...

Gram staining is one way scientists can identify bacteria. Gram-positive bacteria, such as Staphylococcus, appear blue or purple under a microscope when scientists apply a stain. Conversely, ...

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 ...

The results of research led by scientists at Harvard Medical School suggest that a natural product antibiotic first isolated back in the 1940s may be effective against potentially lethal, multidrug ...

Clostridium perfringens is a spore-forming bacteria that can function without oxygen (anaerobic bacteria). These gram-positive bacteria are typically found in human and animal intestines. Bacteria are ...

In a recent study published in the journal Nature, researchers in the United States of America designed and discovered lolamicin, a selective antibiotic that targets the lipoprotein transport system ...

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 ...

There are two main types of bacteria, and these categories reflect the microbes' biology and their vulnerability to different antibiotics. When you purchase through links on our site, we may earn an ...
