In “Virus vs Bacteria: Mortal combat” we learned that bacteriophage (phage) are a group of viruses that literally prey on bacteria and archaea. Phage fill a predatory role in their native ecosystems, helping to keep prey populations in check, in turn preventing exhaustion of available resources. We also explored in “Virus vs Bacteria: Enemy of my enemy” how humans can exploit these bacterial predators to be useful in a number of ways. But there’s quite a bit more to phage than meets the eye. New research is beginning to show us additional ecological impacts phage have on their environments—ones that can play a role in challenges humans face such as climate change and antibiotic resistance.
