title: Comparison of HP1c1 and S2 phages of Haemophilus influenzae.
abstract: Physical maps constructed by localization of the cleavage sites of several restriction endonucleases have shown that the chromosome of Haemophilus influenzae bacteriophage S2 and HP1c1 can possess different types of molecular organization (Piekarowicz, Brzezinski, Smorawinska, Kauc, Skowronek, Lenarczyk & Gołembiewska, 1986). We have compared the physical maps of the HP1c1 and S2 phage DNAs of type B and the results led us to conclude that there are no differences between these two phages of the same type of molecular organization of the genomes, i.e. S2 and HP1c1 is the same phage. We also suggest that some of the fine differences between these two phages noted in some laboratories were induced only by different type of genome of the same phage.
