ResumoAbstract Background Phages infecting spoilage microorganisms have been considered as alternative biocontrol agents, and the study of their genomes is essential to their safe use in foods. UFV-P2 is a new Pseudomonas fluorescens -specific phage that has been tested for its ability to inhibit milk proteolysis. Results The genome of the phage UFV-P2 is composed of bidirectional modules and presented 75 functionally predict ORFs, forming clusters of early and late transcription. Further genomic comparisons of Pseudomonas -specific phages showed that these viruses could be classified according to conserved segments that appear be free from genome rearrangements, called locally collinear blocks (LCBs). In addition, the genome organization of the phage UFV-P2 was shown to be similar to that of phages PaP3 and LUZ24 which have recently been classified as a Luz24likevirus . Conclusions We have presented the functional annotation of UFV-P2, a new Pseudomonas fluorescens phage. Based on structural genomic comparison and phylogenetic clustering, we suggest the classification of UFV-P2 in the Luz24likevirus genus, and present a set of shared locally collinear blocks as the genomic signature for this genus.
