    This study assessed antigen detection reproducibility in staphylococci using serotyping. The method proved highly discriminative, classifying 90.8% of strains into six major groups.

    Area of Science:

    • Microbiology
    • Immunology
    • Bacteriology

    Background:

    • Staphylococci identification is crucial for clinical and epidemiological studies.
    • Accurate serotyping methods are essential for differentiating bacterial strains.
    • Previous methods may have limitations in reproducibility and discrimination.

    Purpose of the Study:

    • To evaluate the reproducibility of antigen detection in staphylococci.
    • To assess the discriminating capacity of a specific serotyping method.
    • To identify the most prevalent serological groups in staphylococcal wild strains.

    Main Methods:

    • Antigenic formulas were determined for 700 wild staphylococcal strains.
    • Reproducibility was assessed through multiple antigen detections.

  • Discriminating capacity was evaluated using 415 selected strains.

    • Main Results:

    • Good reproducibility (over 80%) was achieved for 12 key antigens.
    • The serotyping method demonstrated high discriminative power, with only 1.4% untypable strains.
    • Over 90% of strains were classified into six major antigen groups (A, D, E most important).

    Conclusions:

    • The evaluated serotyping method offers reliable antigen detection reproducibility for staphylococci.
    • The method is highly discriminative, enabling effective bacterial strain classification.
    • Groups A, D, and E represent the most significant serological types in the studied ecological context.
