Some phages use plasmid-encoded conjugation proteins as receptors to infect their bacterial hosts, making their host range dependent on horizontal transfer of the plasmid. Here, the authors present a method for identification of new plasmid-dependent phages, and find that they are common and abundant in wastewater and their genetic diversity is largely unexplored.
