Gram-negative bacteria possess an outer membrane that constitutes a formidable barrier to antibiotic penetration. This envelope, embedded with porins and other specialised channels, governs the ...

A team of researchers at the University of California, Los Angeles (UCLA) has introduced a virtual Gram staining technique that could transform how microbiologists stain and classify bacteria. This ...

Gram-negative bacteria, notorious for their intrinsic and acquired resistance mechanisms, pose a significant threat to public health. The emergence of ...

“It’s genuinely surprising that the add-on gives vancomycin any ability at all to hit gram negatives,” says Kim Lewis, an ...

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 ...

Researchers have determined a protein’s essential role in bacterial envelope structure and function, which could inspire a search for better antibiotics. Researchers at Johns Hopkins University (MD, ...

Scientists at Duke University report they have developed a synthetic antibiotic that could be effective against drug-resistant superbugs and bacteria such as Salmonella, Pseudomonas, and E. coli.

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 ...

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 ...

• Require X (hemin) and/or V (nicotinamide adenine dinucleotide) factors for growth • Responsible for 0.5–1% of all cases of IE • Haemophilus aphrophilus is the most common species responsible for IE ...
