“…Probably they represent strains containing prophages having recombinant conversion specificity. Since it is known that phage G341 will not adsorb to a strain of S. anatum in which the galactosyl residues are not acetylated but that phage e 15 can do so (Uetake & Hagiwara, 1969) it is probable that transductants of type C (sensitive to infection by phage v 15 but on which phage C341 failed to form plaques) carry prophages which have the immunity of phage Lactose-positive transductant strains T 23 a n d T 24 were infected with phage e 16 . P h a g e from these lysates a t low multiplicity (10~3) w a s used t o transduce cells of S. anatum t o lactose-positive phenotype.…”

A bacteriophage was isolated from a strain of Salmonella manilla. This phage, v 15 , was found to have adsorption and conversion properties similar to phage e 15 . The two phages show similar transduction efficiencies but phage v 15 lysogenizes more efficiently. Phage v 15 is not subject to repression by e 15 type prophage. The densities of the two phages are indistinguishable.Phage f 16 can ' cure' e 15 type prophages and recombination is possible between genomes of the two phages. It seems probable that they are heteroimmune representatives of a single bacteriophage family.

Tailed dsDNA bacteriophage virions bind to susceptible cells with the tips of their tails and then deliver their DNA through the tail into the cells to initiate infection. This chapter discusses what is known about this process in the short-tailed phages (Podoviridae). Their short tails require that many of these virions adsorb to the outer layers of the cell and work their way down to the outer membrane surface before releasing their DNA. Interestingly, the receptor-binding protein of many short-tailed phages (and some with long tails) has an enzymatic activity that cleaves their polysaccharide receptors. Reversible adsorption and irreversible adsorption to primary and secondary receptors are discussed, including how sequence divergence in tail fiber and tailspike proteins leads to different host specificities. Upon reaching the outer membrane of Gram-negative cells, some podoviral tail machines release virion proteins into the cell that help the DNA efficiently traverse the outer layers of the cell and/or prepare the cell cytoplasm for phage genome arrival. Podoviruses utilize several rather different variations on this theme. The virion DNA is then released into the cell; the energetics of this process is discussed. Phages like T7 and N4 deliver their DNA relatively slowly, using enzymes to pull the genome into the cell. At least in part this mechanism ensures that genes in late-entering DNA are not expressed at early times. On the other hand, phages like P22 probably deliver their DNA more rapidly so that it can be circularized before the cascade of gene expression begins.
