In scientists’ quest to understand how gut microbes affect human health, bacteria take center stage. But bacteriophages, the viruses that attack the bacteria, are often overlooked, says microbiologist Luisa De Sordi of the Institut Pasteur in France. “We keep an … Continue reading →

Journal Club: Phage find clever ways to infiltrate resistant bacteria and shuttle DNA between strains

Posted on January 24, 2017 by Charlotte Schubert

In the gut, in the soil, and myriad other spots, bacteria reign, forming complex communities—but not in isolation. They’re often influenced by bacteria-killing viruses known as bacteriophages. A recent study in Cell now shows how such viruses can infect bystander, … Continue reading →
