Host population structure and species resolution reveal prophage transmission dynamics.

ABSTRACT: Much knowledge about bacteriophages has been obtained via genomics and metagenomics over the last decades. However, most studies dealing with prophage diversity have rarely conducted phage species delimitation (aspect 1) and have hardly integrated the population structure of the host (aspect 2). Yet, these two aspects are essential in assessing phage diversity. Here, we implemented an operational definition of phage species (clustering at 95% identity, 90% coverage) and integrated the host's population structure to understand prophage diversity better. Gathering the most extensive data set of Acinetobacter baumannii phages (4,152 prophages + 122 virulent phages, distributed in 46 countries in the world), we show that 91% (875 out of 963) of the prophage species have four or fewer pr
