    A new staphylococcal co-agglutination (SA) test accurately detects rotavirus in stool samples. This rapid diagnostic method shows high sensitivity and specificity for identifying rotavirus infections.

    Area of Science:

    • Virology
    • Immunology
    • Diagnostic Microbiology

    Background:

    • Rotavirus is a leading cause of severe diarrheal disease in infants and young children worldwide.
    • Accurate and rapid diagnostic methods are crucial for timely clinical management and epidemiological surveillance of rotavirus infections.

    Purpose of the Study:

    • To describe and evaluate a novel, simple, and rapid staphylococcal co-agglutination (SA) test for the detection of rotavirus in human faecal specimens.

    Main Methods:

    • The SA test utilized protein A-coated staphylococci sensitized with rabbit anti-rotavirus serum.
    • Faecal specimens were pre-treated with uncoated staphylococci to reduce non-specific agglutination.
    • Test performance was compared against immune electron microscopy (IEM).

    Main Results:

    • The SA test correctly identified 34 out of 36 rotavirus-positive samples (94.4% sensitivity).
    • None of the 41 rotavirus-negative samples showed false-positive results (100% specificity).
    • The SA test demonstrated comparable sensitivity to enzyme-linked immunosorbent assay (Rotazyme) and higher sensitivity than latex agglutination (Rotalex).

    Conclusions:

    • The staphylococcal co-agglutination test is a sensitive, specific, and rapid method for rotavirus detection in faecal samples.
    • This SA test offers a valuable alternative for diagnosing rotavirus gastroenteritis, particularly in resource-limited settings.
    • Further validation in diverse clinical settings is warranted to establish its full diagnostic utility.
