Bacteriophages are some of the strangest creatures on Earth. I say ‘creatures’ because they reproduce and they have DNA, but half the time they don’t seem to be alive at all. Even if you have never heard of phages, you are associated with them intimately: they are very small – about 70 nm across the head and 200 nm long – and they live in your gut. Phages are parasites but we are not the prey. Phages prey on bacteria on the principle enunciated by Jonathan Swift:

…a flea

Hath smaller fleas that on him prey;

And these have smaller fleas to bite ‘em,

And so proceed ad infinitum.
