Anti-poly(glycerolphosphate) in human sera

R J Doyle, E M Sonnenfeld, K Cost

    Journal of Clinical Microbiology
    |June 1, 1982
    PubMed
    Summary

    Ultrasonic extracts from staphylococci revealed a poly(glycerolphosphate) teichoic acid antigen. This antigen may explain variations in diagnostic tests for Staphylococcus aureus infection.

    Area of Science:

    • Microbiology
    • Immunology
    • Biochemistry

    Background:

    • Staphylococci are bacteria significant in human infections.
    • Accurate diagnosis of Staphylococcus aureus infections is crucial.
    • Variability in diagnostic tests can hinder effective treatment.

    Purpose of the Study:

    • To identify components in staphylococcal extracts responsible for red blood cell sensitization.
    • To investigate the role of identified antigens in diagnostic test variability.

    Main Methods:

    • Ultrasonic extraction of bacterial components.
    • Detection of red cell-sensitizing activity.
    • Analysis of antigen properties.

    Main Results:

    • Ultrasonic extracts contained poly(glycerolphosphate) teichoic acid antigen.
    • This antigen demonstrated red cell-sensitizing properties.

    Conclusions:

    • Poly(glycerolphosphate) teichoic acid antigen is present in staphylococcal extracts.
    • The antigen's properties may contribute to the observed variability in Staphylococcus aureus diagnostic precipitin reactions.
