Antibiotic susceptibility in resistant bacteria is not static. New research shows that bacteria harboring resistance genes may respond differently to antibiotics if they are tested under conditions ...

New research from the Technical University of Denmark indicates that the outcome of a resistance measurement may depend on the conditions under which the bacterium is tested. Standard laboratory tests ...

When a bacterium becomes resistant to one antibiotic, it may sometimes become more sensitive to another. This biological side ...

A recent review finds that microalgal niches in freshwater ecosystems may concentrate antibiotic resistance genes, raising environmental and public health concerns.

Two newly discovered mechanisms in bacteria have been identified that can contribute to the development of antibiotic resistance. Changing the number of copies of resistance genes in bacteria ...

Antibiotics cannot cure COVID. They don’t help a bit. And yet, new data shows that, during the pandemic, COVID patients were given antibiotics – a lot of antibiotics. That’s bad because the overuse of ...

Antibiotics are medical marvels that have transformed once deadly bacterial infections into manageable conditions. But with a ...

Researchers describe a fundamental mechanism of antibiotic resistance. What happens in a bacterium that is resistant to the antibiotic fusidic acid? With a stop-motion movie at the atomic level, they ...

A new report from the Centers for Disease Control and Prevention on the deadly drug-resistant bacteria NDM-CRE found a 70% rise in infections in the U.S. between 2019 and 2023. Also known as ...

A new World Health Organization study finds 1 in 6 infections worldwide are resistant to some antibiotics, highlighting a growing threat from drug-resistant bacteria. The World Health Organization ...
