Antibiotic resistance is a significant and growing medical problem worldwide. Researchers at the Marine Biological Laboratory (MBL) and collaborators have found a novel genetic arrangement that may ...

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 ...

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. Mareike Saathoff of ...

Since the advent of penicillin more than 90 years ago, antibiotic drugs have saved countless lives by preventing and treating bacterial infections. However, bacteria are rapidly developing new ways to ...

When confronted with an antibiotic, toxic substance, or other source of considerable stress, bacteria are able to activate a defense mechanism using cell-to-cell communication to 'warn' unaffected ...

New drug that disrupts two cellular targets would make it much harder for bacteria to evolve resistance. A new antibiotic that works by disrupting two different cellular targets would make it 100 ...

The guidance aims to help accelerate the development of new antibiotics for severe, drug-resistant gram-negative and gram-positive infections and community-acquired and healthcare-associated bacterial ...

A mechanism of antiviral immunity in bacteria has been characterized. A research team from Umeå University (Sweden) has uncovered a mechanism for how bacteria build up antiviral immunity against ...
