title: [Study of morphology and genome structure of Pseudomonas putida bacteriophages for their classification].
abstract: A group of 27 bacteriophages specific for Pseudomonas putida strains PpG1 and PpN has been isolated. The phages were characterized and compared with the previously described virulent (pf 16, af, tf and PMW) and temperate (PP56 and PP71) phages. The new phages belong to B1 and C1 morphotypes, according to Ackerman's classification. Phage DNAs were digested with several endonucleases; the molecular weights and homology of the DNAs were determined. All phages of P. putida isolated up to now were distributed into 10 species (groups), on the basis of particle morphology, genome size and the results of homology studies. Recombination processes are believed to participate in formation of phages belonging to certain species.
