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).

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 ...

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.

Oral Phage Therapy of Acute Bacterial Diarrhea With Two Coliphage Preparations: A Randomized Trial in Children From Bangladesh

EBioMedicine, 2016
Background: Antibiotic resistance is rising in important bacterial pathogens. Phage therapy (PT), the use of bacterial viruses infecting the pathogen in a species-specific way, is a potential alternative.

Inactivation of coliphage Qβ by potassium ferrate [PDF]

FEMS Microbiology Letters, 1994
The kinetics of inactivation of a bacteriophage by potassium ferrate were studied with the F-specific RNA-coliphage Q beta. Inactivation in phosphate buffer (pH 6, 7 and 8) containing ferrate could be described by Hom's model. The inactivation rate depended on the pH.

Detection of Enteric Viruses in a Pilot System for Municipal Wastewater Treatment

Kasmera, 2014
A pilot system for treating municipal waste was evaluated to verify its ability to remove viral pathogens. The presence of Adeno vi rus, Calicivirus, Enterovirus and Hepatitis A and E was determined using RT-PCR.

Detection of somatic coliphages as indicators of faecal contamination in estuarine waters Detección de colifagos somáticos como indicadores de contaminación fecal en aguas estuarinas

Revista Argentina de Microbiología, 2008
The appearance of enteric disease outbreaks associated with the use of waters considered bacteriologically suitable, calls for the search of new and more precise indicators. Samples of estuarine water were collected in order to quantify E.
