[Study of Brevibacterium flavum phage PhiBSh6].
Properties of a virulent Brevibacterium flavum bacteriophage phi BSh6 were studied. The phage was placed in morphological group B1 according to Ackerman classification, head diameter being 74-3 nm, tail length being 337 +/- 15 nm. The phage was shown to have double stranded DNA as a genetic material. The chromosome is linear having cohesive ends. Chromosome length was estimated to be about 71 kbp by restriction analysis and electron microscopy. A unique EcoRI-EcoRI fragment of bacteriophage DNA (0.8 kbp) was cloned in Escherichia coli. Restriction chart of cos region was determined, the dyad symmetry being absent from cos sequence. Deletion mutant of the phage was obtained and restriction map of the corresponding genome region was constructed. The phage phi BSh6 was shown to be a close relative to phages phi B and BB14 described earlier.
