    Area of Science:

    • Environmental microbiology
    • Water quality assessment
    • Bacteriophage detection

    Background:

    • Coliphages are indicators of fecal contamination in water.
    • Rapid and accurate detection methods are crucial for public health.
    • Existing methods for coliphage detection can be time-consuming.

    Purpose of the Study:

    • To modify and improve the ARCAT method for faster coliphage detection.
    • To enhance the efficiency and accuracy of water quality analysis.
    • To enable rapid estimation of water safety.

    Main Methods:

    • Media optimization for improved coliphage growth.
    • Utilization of frozen host cultures for convenience and consistency.
    • Implementation of a single agar coliphage assay.
    • Optimized plaque resolution using 2, 3, 4-triphenyltetrazolium chloride.

    Main Results:

    • The modified ARCAT method allows for the detection of 5 coliphages per 100 ml of water sample.
    • The assay provides a rapid estimation of water quality within 6 hours.
    • Optimized plaque resolution enhances the accuracy of detection.

    Conclusions:

    • The enhanced ARCAT method significantly reduces the time required for coliphage detection.
    • This technique provides a valuable tool for rapid water quality assessment.
    • The modifications improve the practicality and efficiency of coliphage analysis in water samples.
