Antimicrobial resistance occurs when bacteria or other types of microbes adapt to overcome treatments designed to eliminate them. The evolution of microbes | Immunology ...

Urinary tract infections (UTIs) are common, but increasingly hard to treat because the bacteria that cause them are developing resistance to many antibiotics. Researchers headed by a team at 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 ...

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 ...

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 ...

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 ...
