Scientists in a wide range of medical and biological disciplines, from universities and companies around the world review the understanding of bacterial viruses, or bacteriophages, as it is informed by recent insights from genomics. They consider bioinformatics and genomics, food fermentations, medicine, the Western perspective, host interaction in lactic acid bacteria, the transfer of DNA from phage to host, phrophages and their contributions to host cell phenotype, the release of progeny phages from infected cells, and other topics.
