A new experimental antibiotic can handily knock off one of the world’s most notoriously drug-resistant and deadly bacteria —in lab dishes and mice, at least. It does so with a never-before-seen method ...

Health professionals are in urgent need of new antibiotics to tackle resistant bacteria. Researchers have now modified the chemical structure of naturally occurring peptides to develop antimicrobial ...

Gram-negative bacteria deploy a range of protein toxins as mediators of inter-bacterial competition and pathogenicity. Among these, colicins comprise a class of ribosomally synthesised bacteriocins ...

Antimicrobial resistance (AMR) is increasingly compromising the effectiveness of essential antibiotics, resulting in higher global mortality and morbidity rates. Despite this urgent need, few new ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
