This chapter explores the problem of lysogeny as a challenge to the American Phage Group's framework of shared commitments. The phenomenon of lysogeny occupies a special chapter in the early history of phage. Both the complexity and confusion it generated and the decision by Delbrück to eliminate lysogeny as a central problem for American Phage Group ...

Lysogeny in the Genus Lactobacillus
Nature, 1962WE have reported1 the isolation of 14 phages active on Lactobacilli by the use of an enrichment technique in which 10 batches of sewage were incubated with groups of Lactobacilli. Each group comprised 12 different strains. These experiments have now been repeated with one modification: the sewage in the mixtures has been replaced by an equal volume of ...

Nature, 1959
A LYSOGENIC strain of Proteus species was detected by Fejgin in 19241 but no systematic attempt has ever been made to ascertain the prevalence of such strains. We have investigated the incidence of lysogeny using 23 Proteus strains for which we have previously isolated lytic phages from sewage2; media used have been previously described2,3.

Lysogeny in marine Synechococcus
Nature, 2002Viral infection of bacteria can be lytic, causing destruction of the host cell, or lysogenic, in which the viral genome is instead stably maintained as a prophage within its host. Here we show that lysogeny occurs in natural populations of an autotrophic picoplankton (Synechococcus) and that there is a seasonal pattern to this interaction.

LYSOGENY IN RHIZOBIUM TRIFOLII
Canadian Journal of Microbiology, 1961A phage-like particle (phage i) found in filtrates of Rhizobium trifolii (strain RT 9) did not produce plaques but induced development of two different phages in a presumed defective lysogenic strain (RT 10). These induced phages (phages 9 and 10) differed in their host ranges and produced plaques on strains RT 9 and RT 10, respectively.

Folia Microbiologica, 1969
Our investigations to detect naturally lysogenic strains of mycobacteria were limited to 1 strain ofMycobacterium smegmatis, 4 strains ofMycobacterium borstelense var.niacinogenes, and to 5 strains ofMycobacterium marinum (Syn:Mycobacterium balnei), all together 10 strains.

Lysogeny in Streptococcus bovis
Canadian Journal of Microbiology, 1976Forty-eight strains of Streptococcus bovis were tested for induction with mitomycin C. Eleven inducible strains were found and the lysates of all 11 contained bacteriophage-like particles. The lysate of one strain also contained large numbers of particles which closely resembled polyheads. Eight of the lysates produced zones of inhibition on indicator

LYSOGENY IN PSEUDOMONAS AERUGINOSA
Australian Journal of Experimental Biology and Medical Science, 1960SUMMARYAn investigation has been made into lysogenicity and pyocinogenicity in Pseudomonas aeruginosa. The bacteriophages isolated were classified into groups on their antigenic properties and attempts have been made to correlate biological characteristics with this grouping.
