Abstract: (Bacterio)phage PVP-SE1, isolated from a German wastewater plant, presents a high potential value as a biocontrol agent and as a diagnostic tool due to its broad lytic spectrum against different Salmonella strains, even compared to the well-studied typing phage Felix 01. Sequence analysis of its genome (145,964 bp) shows it to be terminally redundant and circularly permuted. The mol% G+C content, 45.6, is lower than that of its hosts (50-54). A total of 244 ORFs were found, representing 91.6% of the coding capacity of the genome. Approximately 46% of encoded proteins are unique to this phage while 22.1% of the proteins could be functionally assigned. This myovirus encodes a large number of tRNAs (24), reflecting the lytic capacity and evolution through different hosts. Tandem mass spectrometric analysis using electron spray ionization revealed 25 structural proteins as part of the mature phage particle. The genome sequence was found to share homology with the Escherichia coli bacteriophage rV5 in 140 proteins. Both phages are unrelated to any other known virus, which suggests that a "rV5-like virus" genus should be created within the Myoviridae to contain these two phages.
