Development of a Rapid Coliphage Assat
A rapid coliphage detection assay (RCDA), based on the phage-induced release of b-galactosidase from cells of Escherichia coli (Ijzerman, M., J.O. Falkinham III and C. Hagedorn. (1993) [A liquid, colorimetric presence-absence coliphage detection method. J. Virol. Meth. 45:229-234] was modified to …

Development and evaluation of a colorimetric coliphage assay detection system
A Colorimetric Coliphage Assay Detection System (CCADS) that is composed of a Liquid Colorimetric Presence-Absence (LCPA) method and a Colorimetric Agar-Based (CAB) method was developed to overcome the limitations imposed by the Standard Methods for the Examination of Water and Wastewater …

Enteric adenovirus and coliphage as microbial indicators in Singapore's Kallang Basin
… This study focuses on enteric adenovirus and coliphage (F' male-specific and somatic) as potential alternative indicators of fecal contamination. Adenovirus and coliphage concentrations from water samples collected over a 48-hour period were quantified using qPCR assay and cell culture …

A performance study of ceramic candle filters in Kenya including tests for coliphage removal
… subjected to tests for viral removal using MS2-coliphages. Results from studies indicated that the Pelikan filters were the most effective at removing turbidity from Charles River water (97% reduction). Turbidity removal by other filters ranged from 88%-94%. Results from studies utilizing more …

Virus in sewage, polluted water and molluscan shellfish: a critical assessment of coliphage as a possible indicator organism
… risks from viruses. Literature in respect of coliphages has also been reviewed as an introduction to the experimental section of this present study. which looks at some of the factors influencing bacteria, viruses and phage in sewage and the marine environment. This study has thrown new light …

Phage host range and definition of genes implicated in Type III toxin-antitoxin-mediated abortive infection
… several novel and rare phages). Previously, no coliphage was identified that was capable of escape of the ToxIN$_P$$_a$ or TenpIN$_P$$_l$ systems. However, this study defined and characterised the first ToxIN$_P$$_a$ and TenpIN$_P$$_l$ coliphage escapes as well as a new method for isolating …

Assessment of ultraviolet light disinfection efficiency of advanced wastewater treatment plant effluent
… {dollar}>{dollar}4-log removal of seeded MS-2 coliphage at UV dosages of 80-100 milliwatt-seconds per square centimeter (mW-s/cm{dollar}\sp2{dollar}), and consistent removal of fecal and total coliforms to less than 2.2 MPN/100 mL at dosages in the vicinity of 50-80 mW-s/cm{dollar}\sp2{dollar} …

Phage Display to Identify Peptides Binding to or Penetrating the Mouse Zona Pellucida
… intracytoplasmic components. Specifically, M13 coliphage 7-mer, 12-mer and 15-mer random peptide libraries were used separately for biopanning. Peptides derived from the amplified pools were sequenced and studied. The phage display for in vivo ovary experiments yielded no pool of peptides after …

Characterization of the repressor from the lambdoid phage HK022.
The lambdoid coliphage HK022 can grow in either a lytic or lysogenic mode following infection. In λ phage the switch to either mode is controlled by the cI and Cro repressors which bind to operators in the λ chromosome and regulate gene expression of adjacent promoters. HK022 is organized similar …

Resin-based method for concentration of enteric viruses and F-RNA coliphages from water samples
… viral indicators of fecal contamination. F-RNA coliphages are recognized as enteric virus surrogates, fecal indicators useful for source tracking. Enteric viruses and F-RNA coliphages are often present at low concentrations in contaminated waters; therefore rapid, sensitive and cost effective …

Application of Quantitative Microbial Risk Assessment to Domestic Hygiene
… be a necessity. Hand-to-toilet transfer of MS-2 coliphage was highest with the MEM of highest protein content (American Society of Standard Methods (ASTM) Tripartite soil load). Yet finger-to-lip transfer was significantly higher with the lowest protein content MEM and phosphate buffered saline. …

Structure-Function Relationships of Elements of the Bacteriophage f1 Genome
… during the infection cycle, since this nonlytic coliphage lives in delicate balance with its host. The sequence and context requirements of specific regions involved in f1 mRNA metabolism were investigated by: 1) relocation of an intact transcription unit on the phage genome; 2) construction of a …

Validating Pathogen Reduction in Ozone-Biofiltration Water Reuse Applications
… microorganisms (e.g. spore forming bacteria, coliphage) was quantified across the upstream wastewater treatment process and the AWT. In general, the removal of surrogate microorganisms was less than or equal that of the pathogens of interest thereby justifying their use in full-scale …

Recombination and Excision: DNA Repair Proteins in Prokaryotic Host-Virus Conflicts
… from the genome of T-even phages, such as coliphage T4, to generate abasic sites that inhibit DNA replication, which constitutes a novel anti-phage defense mechanism. Many phages have evolved to introduce DNA modifications to avoid recognition and cleavage by bacterial nucleases, including …
