Author Contributions

MBS grew, purified, and extracted DNA from the phages. Non-authors (see Acknowledgments) prepared clone libraries, sequenced the inserts, and assembled the genomes. MBS, MLC, and FR did the majority of the genome annotation, while PW evaluated tail-fiber-related genes and provided electron micrographs of the particles. MBS and SWC wrote the majority of the paper with significant contributions from all authors, as well as non-authors (detailed in the Acknowledgments).
