Prophage mapping by transformation
Virology, 1969Abstract A procedure is described for the preparation and isolation of defectively lysogenic strains of Hemophilus influenzae carrying prophage HP1. A quantitative technique for the assay of wild-type lysogenic transformants has been developed. A number of defective prophage mutants have been mapped by transformation in reciprocal two-point crosses ...

Characterizing prophages in the genus Fusobacterium
Anaerobe, 2023We set out to identify and characterize prophages within genomes of published Fusobacterium strains, and to develop qPCR-based methods to characterize intra- and extra-cellular induction of prophage replication in a variety of environmental contexts.Various in silico tools were used to predict prophage presence across 105 Fusobacterium spp.

Research in Microbiology, 2003
Insertion of viral DNA into host chromosomes is an ancient process essential for propagation in the proviral form. Many present-day bacteriophages insert at specific sites on the host chromosome. Insertion by two coliphage families (lambdoid and P4-like) is compared. For both families, insertion sites frequently lie within tRNA genes.

Prophages and Cryptic Prophages
1998A large group of natural bacteriophages (called temperate) can establish a permanent relationship with their hosts (lysogeny), where most viral functions are repressed and the phage genome (prophage) is transmitted vertically from mother to daughters at cell division.

[Virus and prophages in aquatic ecosystems].
Canadian journal of microbiology, 2009Dans cette revue bibliographique, nous résumons les données acquises sur la structure (diversité, abondance, biomasse) et l’importance fonctionnelle (bactériolyse, lysogénie, transferts de gènes, régulation de la diversité des procaryotes) des virus d’origine naturelle, dans le contexte de la chaîne alimentaire en écologie microbienne aquatique et des ...

Induction of prophage lambda by chlorophenols
Environmental and Molecular Mutagenesis, 1990AbstractChlorinated phenols, which are used primarily as wood preservatives and fungicides, are present in most air, water, and soil samples in industrialized areas as well as in the urine of most people. We have examined the ability of phenol and the 19 isomers of chlorophenol to induce DNA damage using the Microscreen prophage‐induction assay in ...

Prophage distribution in coryneform bacteria
Research in Microbiology, 1995Four temperate bacteriophages of corynebacteria were isolated after UV induction. Phages phi 304L and phi 304S were both induced from Corynebacterium glutamicum ATCC 13058, ATCC 21488, ATCC 21649 and ATCC 21650 strains, and have no known sensitive host. Phages phi 15 and phi 16 were both induced from ATCC 14020 and ATCC 21792.

Defective prophages of bacteriophage Mu
Molecular and General Genetics MGG, 1976A method is described for the isolation of thermoinducible defective Mu lysogens. Four of these defective lysogens were studied more extensively. By marker-rescue experiments it was shown that the strain harbouring the smallest defective prophage contains the immunity gene cts and the genes A and B; the strain with the largest defective prophage still ...

The replication of prophage P1 DNA
Molecular and General Genetics MGG, 1974In a synchronized culture of E. coli K12, prophage P1 DNA did not replicate at a specific stage in a cell cycle. It was shown that prophage P1 DNA is able to replicate independently of the initiation of the host mutated in N167. The presence of one copy of P1 DNA per bacterial chromosome was generally observed.
