[New temperate Pseudomonas aeruginosa phage, phi297: specific features of genome structure].

The genome structure and some specific features of temperate Pseudomonas aeruginosa phage phi297 are considered. Analysis of sequencing data and genome annotation suggest that the phi297 genome displays a mosaic structure, which has formed through combining gene blocks from bacteria of taxonomically remote groups and/or their phages. The results of a comparison of the phi297 DNA homology level and pattern with the genome sequences of the currently known related P. aeruginosa bacteriophages are interpreted from the perspective of assumed active migration of these phages between different bacterial species.
