Abstract: The present disclosure relates to Staphylococcus aureus leukocidin A (LukA) and leukocidin B (LukB) variant polypeptides, and polynucleotides encoding the LukA, LukB and LukAB variant polypeptides. The present disclosure further relates to vaccine compositions comprising these LukA and LukB variants, and methods of generating an immune response against Staphylococcus aureus in a subject.

Abstract: The disclosure is directed to antibodies that bind to Staphylococcus aureus bi-component leukotoxins and/or gamma-hemolysins. Other aspects of the disclosure are directed to pharmaceutical compositions and diagnostic kits containing the leukotoxin and hemolysin antibodies, and therapeutic and diagnostic methods utilizing the leukotoxin and hemolysin antibodies.

Abstract: The present application generally relates to multi-specific molecules that bind to multiple bacterial virulence factors, methods for producing these binding molecules, and the use of these binding molecules to treat bacterial infections. In particular, the binding molecules comprise at least two binding domains, preferably an antibody or antibody fragment and an alternative scaffold. The first binding domain is capable of binding to a glycosylated staphylococcal surface protein, preferably an SDR-containing protein. The second binding domain is capable of binding to a staphylococcal leukotoxin, preferably LukAB, LukD or LukE. These multi-specific binding compounds have killing activity against staphylococci and, thus, can be used in the treatment and/or amelioration of a Staphylococcus infection, including methicillin-resistant Staphylococcus aureus.
