But as yet the evolutionary 'arms race' between bacteria and their viral foes is poorly understood.

In a new study published this week in PNAS a team led by Oxford University scientists report a series of experiments examining this eternal war between bacteria and bacteriophages focusing on the bug Pseudomonas aeruginosa. I asked Alex Betts of Oxford University's Department of Zoology, first author of the study, about how we might recruit bacteriophages to fight for us…
