    Area of Science:

    • Microbiology
    • Epidemiology
    • Bacteriology

    Background:

    • Salmonella remains a significant public health concern, necessitating accurate identification and tracking methods.
    • Phage typing is a valuable tool for differentiating bacterial strains, crucial for understanding transmission dynamics.

    Purpose of the Study:

    • To develop and validate a comprehensive phage-typing system for commonly isolated Salmonella serovars.
    • To establish a reproducible method for epidemiological surveillance of Salmonella.

    Main Methods:

    • Isolation and characterization of 50 phages from sewage sources.
    • Typing of 735 Salmonella cultures representing 58 serovars across multiple groups.
    • Analysis of 347 unique phage patterns observed.

    Main Results:

    • All tested Salmonella cultures were successfully typed using the developed phage set.
    • The system delineated 58 serovars based on 347 reproducible phage patterns.
    • Characteristic patterns linked Salmonella isolates from various outbreaks, confirming epidemiological relationships.

    Conclusions:

    • The described phage-typing system provides a reliable and reproducible method for Salmonella serovar characterization.
    • This system enhances the ability to trace the source and spread of Salmonella infections during outbreaks.
    • The phage-typing approach is crucial for effective public health surveillance and control of Salmonella.
