Abstract
Antibodies having Fab regions that specifically bind to Staphylococcus aureus protein A are capable of mediating opsinization of Staphylococcus aureus bacteria despite their expression of antibody-neutralizing protein A. These antibodies and antigen-binding fragments thereof can be used in methods of treating and/or preventing Staphylococcus aureus infections.
