Coliphages as viral indicators of sanitary significance for drinking water [PDF]

Frontiers in Microbiology, 2022
Coliphages are virus that infect coliform bacteria and are used in aquatic systems for risk assessment for human enteric viruses. This mini-review appraises the types and sources of coliphage and their fate and behavior in source waters and engineered ...

Coliphages as fecal pollution and removal bacterial indicators in the drinking water process [PDF]

Revista Peruana de Biología, 2013
This work compare the efficiency of water treatment from Rimac river. Samples from different phases of water treatment (decanted, filtered and chlorinated) were compared with not treated samples.

Adsorption of Coliphages to Particulates

Water Science and Technology, 1986
Adsorption characteristics of coliphages (host cell: E. coli B) to particulates (kaolin, sand, soil, microbial particulates in an oxidation pond) were investigated using batch experiments under various conditions of pH, concentrations of cations and concentrations of dissolved oxygen.

Polyvalent Coliphages in Sewage

Water Science and Technology, 1991
High concentrations of coliphages were isolated during December and March when the maximum average daytime temperature reaches 20°C. Eight coliphages capable of infecting various strains of E. coli and a few selected members of Enterobacteriaceae were isolated.

Virulent coliphages in 1-year-old children fecal samples are fewer, but more infectious than temperate coliphages [PDF]

Nature Communications, 2020
The impact of bacteriophages in the human gut microbiome remains poorly understood. Here, the authors characterize coliphages isolated from a large cohort of 1-year-old infants and show that temperate coliphages dominate, while virulent ones have greater

A prophage-encoded sRNA limits phage infection of adherent-invasive E. coli. [PDF]

PLoS Pathogens
Prophages are prevalent features of bacterial genomes that can reduce susceptibility to infection by competing phages, yet the mechanisms involved are often elusive.

Occurrence of male-specific and somatic coliphages and relationship with rainfall in privately-owned wells from peri‑urban and rural households

Water Research X, 2021
Privately-owned drinking water wells serving fewer than 25 people (private wells) are prevalent and understudied across most of the US. Private wells primarily serve rural households located outside of municipal drinking water and sewerage service ...
