New Genera and Species of and Bacteriophages Provide Insights into Phage Genome Evolution.

Previous studies have identified diverse bacteriophages that infect strain CB15 ranging from small RNA phages to four genera of jumbo phages. In this study, we focus on 20 bacteriophages whose genomes range from 40 to 60 kb in length. Genome comparisons indicated that these diverse phages represent six phage genera and one additional genus that includes both and phages.
