Characterization of a ViI-like Phage Specific to Escherichia coli O157:H7

Virology Journal, 2011
Phage vB_EcoM_CBA120 (CBA120), isolated against Escherichia coli O157:H7 from a cattle feedlot, is morphologically very similar to the classic phage ViI of Salmonella enterica serovar Typhi. Until recently, little was known genetically or physiologically

Somatic coliphages are conservative indicators of SARS-CoV-2 inactivation during heat and alkaline pH treatments

, 2021
High concentrations of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) genome have been described in wastewater and sewage sludge. It raises the question of the security of land sludge disposal practices during a pandemic.

Development of a Novel Quantitative PCR Assay for Somatic Coliphages to Advance Water Safety Diagnostics

npj Clean Water
Somatic coliphages are recognized reliable indicators of faecal contamination in water. Their routine monitoring relies on time-consuming, labour-demanding culture-based methods, which are limited to detecting total somatic coliphages. Here, we developed

DETECTION OF STX2 COLIPHAGES IN STRAIN OF ESCHERICHIA COLI ISOLATED FROM BOVINE FLEECE AND MILK FILTERS

Italian Journal of Food Safety, 2011
Lambda(4)-phage vectors of gene codifying for synthesis of Shiga-toxins are suspected to be involved in the virulence evolution of Vero-Toxin producing Escherichia coli(VTEC).

Nucleotide sequence of a single-stranded RNA phage from Pseudomonas aeruginosa:Kinship to coliphages and conservation of regulatory RNA structures

, 1995
We report the complete nucleotide sequence of the single-stranded RNA phage PP7 from Pseudomonas aeruginosa.There are three open reading frames which code for apparent protein homologues of the single-stranded RNA coliphages, i.e., maturation protein ...

Water and Wastewater Disinfection with Peracetic Acid and UV Radiation and Using Advanced Oxidative Process PAA/UV

International Journal of Photoenergy, 2015
The individual methods of disinfection peracetic acid (PAA) and UV radiation and combined process PAA/UV in water (synthetic) and sanitary wastewater were employed to verify the individual and combined action of these advanced oxidative processes on the ...

In situ replication studies of somatic and male-specific coliphages in a tropical pristine river

, 1995
The present study was carried out in order to evaluate coliphage survival and their ability to replicate in tropical aquatic environments. Results showed that coliphages survived for extended periods of time, however, neither sewage isolates nor ...

STUDIES ON THE COLIPHAGE T3

Uirusu, 1961
1. A lysate of a high T3 titer was obtained by the following procedure. Escherichia coli B of logarithmic phase was centrifuged down and resuspended in a fresh medium at the concentration of ca. 5×109/ml and infected with T3 (multiplicity of infection =1/20) and shaken at 37°C. The phage titer of the resulting lysate reached usually 3-5×1011/ml.2.
