A new analysis shows that infectious bacteria exposed to the antibiotic albicidin rapidly develop up to a 1,000-fold increase in resistance via a gene amplification mechanism. A new analysis shows ...

Last fall, more than 100 people in 14 states got sick after eating at McDonald’s. The Centers for Disease Control and Prevention traced the outbreak to raw onions on the quarter-pounder hamburger, ...

Antibiotic resistance is a global health challenge that could overtake cancer mortality within a few decades. In a new study, researchers at Umeå University, Sweden, show that the emergence of ...

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 ...

Bacteria modify their ribosomes when exposed to widely used antibiotics, according to research published in Nature Communications. The subtle changes might be enough to alter the binding site of drug ...

This process, for example, contributes mainly to spreading antibiotic resistance from initially only a few bacteria to entire populations, and also across different species boundaries. It is still ...

Antimicrobial resistance is largely due to the overuse of antibiotics in humans, animals, and plants, with nearly all regions ...

As more and more bacteria develop resistance to the drugs designed to kill them, a new study has found that even a relatively new antibiotic isn’t immune. Researchers have uncovered a gene ...

CORRECTED September 30, 2025 // An earlier version of this article incorrectly stated the two drugs which are effective against NDM-CRE. The article has been updated to state aztreonam-avibactam and ...

Scientists describe a new mechanism impacting the phage-bacterial arms race, a nanosized epibiotic parasite, TM7x, which helps its host bacterium (a Schaalia odontolytica strain called XH001) achieve ...
