摘要

The present invention relates to: a composition containing, as an active ingredient, wall teichoic acid (WTA)-attached peptidoglycan (PGN); a method for preventing or treating Staphylococcus aureus infection by using the composition; and a method for preparing soluble wall teichoic acid-attached peptidoglycan (WTA-PGN), which can be used as an active ingredient in the composition. The composition of the present invention can be utilized for the prevention or treatment of Staphylococcus aureus infection by: opsonophagocytosis caused by an antigen-antibody reaction; and neutrophil-mediated phagocytosis caused by T cell activation during the early stage of infection.
