    Summary

    Coliphages are effective viral indicators in polluted water, offering faster, cheaper detection than enteroviruses. Their prevalence and resistance make them ideal for monitoring water safety.

    Area of Science:

    • Environmental microbiology
    • Virology
    • Water quality assessment

    Background:

    • Enteric viruses in wastewater pose public health risks via the fecal-oral route.
    • Current enterovirus detection methods are costly, time-consuming, and require specialized expertise.
    • Coliphages, prevalent in sewage and polluted waters, are potential viral indicators.

    Purpose of the Study:

    • To evaluate coliphages as viable indicators for enteric viruses in water.
    • To compare the characteristics of coliphages and enteroviruses as indicators.

    Main Methods:

    • Comparative analysis of coliphage and enterovirus prevalence in wastewater.
    • Assessment of resistance to environmental conditions (chlorination, water quality).
    • Evaluation of detection time and cost-effectiveness.

    Main Results:

    • Coliphage to enterovirus ratio in wastewater is approximately 10(3):1.
    • Coliphages demonstrated greater resistance to chlorination and longer survival in varying water quality compared to enteroviruses.
    • Coliphage quantification was completed within 24 hours, significantly faster than enterovirus detection (about a week).

    Conclusions:

    • Coliphages meet key criteria for ideal viral indicators in water.
    • Their faster, more cost-effective detection supports their use in routine water quality monitoring.
    • Coliphage monitoring is already implemented in some global regions for water safety assurance.
