Lysogenic Conversion in Staphylococci
Nature, 1962BACTERIA carrying a prophage generally differ from the parent strain in one or more properties1. The presence of the prophage may produce a new character as in Corynebacterium diphtheriae2 or suppress a property of the parent strain. In Staphylococci resistance to erythromycin can be (inversely) related to the presence of a prophage3.

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

Immunity of Lysogenic Bacteria
Nature, 1956BACTERIAL virus (phage), in its symbiotic phase (prophage), renders the host bacterium lysogenic, and confers on it immunity against lysis by free phage particles of the homologous type, whether temperate or virulent in character. Hyper-virulent mutants, which are rare, may be exceptions to this rule.

Lysogenization by bacteriophage lambda
Molecular and General Genetics MGG, 1973An 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, 1967When 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]
Nature, 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, 1969Two 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, 2007Shiga-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.

Lysogenicity of Vibrio Cholerae
1983In 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 ...
