Replication of coliphage lambda DNA [PDF]
FEMS Microbiology Reviews, 1995 A general scheme of lambda phage and plasmid DNA replication in Escherichia coli is presented, and results of in vivo experiments from the authors' laboratory are superimposed. The initiator lambda O functions in the assembly of the replication complex (RC) at ori lambda, making it a stable component of this structure.

Morphological Variants of Coliphage P1 [PDF]
Journal of Virology, 1970 Lysates of P1 from all hosts tested contained at least three morphological variants with respect to head size. These were termed “big” (P1B), “small” (P1S), and “minute” (P1M). Since successive clonings of plaques isolated on many different hosts failed to change the proportions of the variants, we concluded that the production of variants

Water Science and Technology, 2023 Since 2020, there is a new European Regulation (EU, 2020/741) on minimum requirements for water reuse, where routine and validation monitoring requirements (log reductions of indicator microorganisms and reference pathogens) have been established.

Methodology for enumeration of coliphages in foods [PDF]
Applied and Environmental Microbiology, 1986 The effects of eluent composition, pH, and chaotropic agents on the recovery of T2, MS2, and indigenous coliphages from various foods were investigated. Additionally, methods of sample suspension and clarification were evaluated for coliphage recovery and application to various foods.

Coliphages as indicators of enteroviruses [PDF]
Applied and Environmental Microbiology, 1984 Coliphages were monitored in conjunction with indicator bacteria and enteroviruses in a drinking-water plant modified to reduce trihalomethane production. Coliphages could be detected in the source water by direct inoculation, and sufficient coliphages were detected in enterovirus concentrates to permit following the coliphage levels through different ...

Genotyping male-specific RNA coliphages by hybridization with oligonucleotide probes. [PDF]
, 1995 F-specific (F+) RNA coliphages are prevalent in sewage and other fecal wastes of humans and animals. There are four antigenically distinct serogroups of F+ RNA coliphages, and those predominating in humans (groups II and III) differ from those ...

Localization of Coliphage MS2 A-Protein [PDF]
Journal of Virology, 1974 The purification of coliphage MS2 dinitrophenol (DNP) conjugates provided a system for localization of the single molecule of A-protein in the capsid of the MS2 phage particle. Three A-protein preparations isolated from unconjugated MS2, overconjugated DNP-MS2, and purified 78 S DNP-MS2 were tested for the presence ...
