Animal and plant viruses have always received most of our scientific attention, because they pose a direct threat to our health, and that of our livestock and crops. The well-being of bacteria has, understandably, been of less concern, yet the battle between viruses and bacteria is brutal: scientists estimate that phages cause a trillion trillion infections per second, destroying half the world’s bacteria every forty-eight hours. As we are now all too aware, animal-specific viruses can mutate enough to infect a different animal species.
