Lysogeny in the Genus Lactobacillus [PDF]
Nature, 1962 WE 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 These experiments have now been repeated with one modification: the sewage in the mixtures has been replaced by an equal volume of ...

Lysogeny in marine Synechococcus [PDF]
Nature, 2002 Viral 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 [PDF]
Canadian Journal of Microbiology, 1961 A 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.

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.

Enterocinogeny and Lysogeny in Enterococci
Journal of Applied Bacteriology, 1970Summary.The enterocinogeny and lysogeny of enterococci was studied with a double layer agar method and 21 indicator strains of enterococci. Of 77 strains examined, 76 produced enterocine, and of 19 strains examined, 5 were sensitive to their own enterocine. All 77 strains were lysogenic when cultures killed with chloroform were examined for lysogeny by

Publisher Summary Lysogeny and transduction describes a type of phage/host interaction and a method of bacterial gene transfer (procaryotic sex), respectively. This chapter describes methods that have been found useful in studying lysogeny and transduction in the marine environment. Lysogeny occurs when a phage enters into a stable symbiosis with its

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.

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 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
