COMPOSITIONS AND METHODS FOR DETECTING STAPHYLOCOCCOUS INFECTIONS

摘要

Provided herein are compositions and methods for detecting and/or diagnosing a Staphylococcus aureus (S. aureus) infection in a subject. It is a surprising finding of the present invention that an S. aureus infection may be detected by using one or more antigens selected from the group consisting of an IsdA antigen, IsdB antigen, CHIPS antigen, and a SCIN antigen. In some embodiments, these S. aureus antigens are used to detect antibodies secreted by the plasmablasts from the subject.
