    Area of Science:

    • Environmental Microbiology
    • Water Quality Assessment
    • Microbiological Testing

    Background:

    • Fecal coliforms are key indicators of water contamination.
    • Traditional methods like Most Probable Number (MPN) and Fermentation Medium (FM) can be time-consuming and difficult to perform with high sample volumes.
    • There is a need for efficient and reliable methods for fecal coliform analysis in marine environments.

    Purpose of the Study:

    • To describe a simple and rapid test for fecal coliform analysis in seawaters.
    • To evaluate the performance of the direct seeding method on m-FC agar.
    • To propose this method as a viable alternative to conventional techniques.

    Main Methods:

    • Direct seeding of seawater samples onto selective-differential m-FC agar medium.
    • Evaluation of test sensitivity, specificity, and reliability.
    • Comparison with traditional fecal coliform analysis techniques (MPN and FM).

    Main Results:

    • The direct seeding method on m-FC agar demonstrated good sensitivity.
    • The test exhibited high specificity and reliability in fecal coliform detection.
    • The method proved to be a practical and easy-to-perform alternative for analyzing large numbers of seawater samples.

    Conclusions:

    • The direct seeding method on m-FC agar is a simple, rapid, and reliable test for fecal coliform analysis in seawaters.
    • This method offers a practical advantage over traditional techniques, especially when dealing with a high volume of samples.
    • The proposed test is suitable for routine water quality monitoring and can be used alongside or instead of conventional methods.
