A single β-lactam exposure rapidly drives stable multidrug resistance in RecA-deficient bacteria through an SOS-independent mechanism involving oxidative stress-induced mutagenesis and ...

Discover 8 powerful natural antibiotics that actually work for healing. From garlic to honey, these ancient remedies are ...

The more frequently antibiotics are used, the faster pathogens evolve mechanisms to evade their effects. This leads to resistant pathogens against which common antibiotics are no longer effective.

Now that the mechanism has been identified, the researchers are using chemical and mechanical manipulations to disrupt the process, so that antibiotics can work unimpeded.

A Cornell University-led collaboration has uncovered the equipment that enables bacteria to survive exposure to antibiotics: a shuttling mechanism that helps a complex of proteins pump out a wide ...

Protein shuttling mechanism helps bacteria pump out antibiotics Date: February 12, 2025 Source: Cornell University Summary: Scientists have uncovered the equipment that enables bacteria to survive ...

A new study from the University of Sheffield reveals that MRSA has developed a second defense mechanism against antibiotics, allowing it to reproduce despite antibiotic exposure. This discovery opens ...

There are many ways to kill microbes that cause dangerous infections. Combining genetic screening with machine learning can help researchers identify new antimicrobials.

Mark Fletcher/Unsplash Bacteria vs antibiotics While bacteria have developed mechanisms to resist antibiotics, these adaptations can come at a “fitness” cost.

Penicillin belongs to the beta-lactam family of antibiotics, the members of which use a similar mechanism of action to inhibit bacterial cell growth that eventually kills the bacteria.
