Antibiotic exposure can ‘prime’ single-resistant bacteria to become multidrug-resistant

Antibiotics save lives — but using them also helps antibiotic-resistant strains evolve and spread. Each year, antibiotic-resistant bacteria infect some 2.8 million people in the United States, killing more than 35,000, according to the Centers for Disease Control and Prevention. Infections by multidrug-resistant — or MDR — bacteria, which are resistant to two or more… Read More »

New discoveries map out CRISPR-Cas defense systems in bacteria

With the aid of highly advanced microscopes and synchrotron sources, researchers from the University of Copenhagen have gained seminal insight into how bacteria function as defence mechanisms against attacks from other bacteria and viruses. The study, which has just been published in the journal, Nature Communications, also describes how the defence systems can be activated… Read More »
