There’s a lot that scientists don’t know about the gut microbiota, and when it comes to the viruses present there they know even less. To learn more, researchers have monitored the gut viromes of nine people for a full year and that of one person for more than two years. They find that many types of bacteriophages are present and that each individual’s virome is stable over time and different from that of the other subjects.
This study “generates an important database for phages in the gut,” says Corrine Maurice, a microbiologist at McGill University who did not participate in the work. “That’s a database that we just didn’t have, and so that data is going to allow us to formulate some really cool hypotheses going forward. It’s really providing us with tools to ...
