λ Lysogens of E. coli reproduce more rapidly than non-lysogens [PDF]

open access: possibleNature, 1975
THE evolutionary basis for the integration of phage DNA into bacterial chromosomes (lysogeny1,2) is not understood. A generally accepted explanation is that when the bacterial population is large and growing well, the phages prefer the lytic pathway since they can multiply without elimination of all host bacteria.

Lysogenization by bacteriophage lambda

Molecular and General Genetics MGG, 1973
An easy and sensitive way of measuring the proportion of E. coli cells which are lysogenized by lambda phage or lambda mutants has been devised. With this assay it was possible to analyse the lysogenic response as a function of the average phage input per cell.

Abortive lysogenization of bacteriophage lambda b2 and residual immunity of non-lysogenic segregants

Journal of Molecular Biology, 1967
When Escherichia coli infected with λb2 at a high multiplicity was incubated, the phage is transmitted unilinearly to the descendants, and non-lysogenic cells are segregated. The non-lysogenic cells are immune for about four generations after segregation.

Lysogenic Conversion in the Genus Proteus [PDF]

open access: possibleNature, 1961
THE presence of prophage renders a bacterial cell immune to homologous bacteriophage. Homologous phage often adsorbs and penetrates the immune cell but does not undergo reduction to prophage and its genetic material is gradually ‘diluted out’ during multiplication of the cell1.

Phages of lysogenic Thermoactinomyces vulgaris

Archiv f�r Mikrobiologie, 1969
Two phages isolated from Thermoactinomyces vulgaris multiplied optimally at 55–60°, and were inactivated at 80°. The two isolates had similar growth characteristics, host-range, serology and morphology. Tadpole-shaped with an elongated head, they resemble other actinophages, with long tail lacking contractile sheath and they seem specific to T ...

Modelling the stability of Stx lysogens

Journal of Theoretical Biology, 2007
Shiga-toxin-converting bacteriophages (Stx phages) are temperate phages of Escherichia coli, and can cause severe human disease. The spread of shiga toxins by Stx phages is directly linked to lysogen stability because toxins are only synthesized and released once the lytic cycle is initiated.

Lysogenization by satellite phage P4

Virology, 1981
Abstract Satellite phage P4 attaches to the E. coli K-12 chromosome at a preferred site near 96 min. The attachment site on the P4 genome is 31.4–36.5% from the left cohesive end, which has been redefined as the end with the same base sequence as the P2 helper phage left end. The P4 int gene is in the region from 27.5 to 31.4%. Immunity-sensitive

The steric effect in lysogenization by bacteriophage λ

Virology, 1969
Abstract A strain of Escherichia coli diploid for the λ attachment site was made lysogenic for the heteroimmune hybrid phage λ imm434 or the deletion-defective prophage λ cryptic. When these strains were superinfected with wild-type λ, most of the double lysogens produced carried the superinfecting phage at the initially unoccupied site ( trans ...

Lysogenicity of Vibrio Cholerae

1983
In 1963, Takeya and Shimodori described a certain temperate phage infecting a majority of strains of Vibrio cholerae biotype eltor isolated in the western Pacific region and named it as kappa type phage(1). Then, on the basis of the individual strains’ lysogenicity by, and their sensitivity to, this phage, they classified the eltor type vibrio into ...
