Soil pH influences the composition of bacteriophage communities infecting individual hosts Bacteriophages (phages) are predicted to infect a range of hosts in highly diverse soil bacterial communities. However, selection of host communities …

Hot off the press! 📣
We demonstrate that soil physicochemical gradients alter virus community structure but not the presence of those infecting individual (cultivated) bacteria hosts 🦠🧫
