  • Publication number: 20230382980
    Abstract: The present invention relates to peptides, particularly human monoclonal antibodies, that bind specifically to poly-N-acetyl glucosamine (PNAG), such as Staphylococcal PNAG, in acetylated, partially acetylated and/or fully deacetylated form. The invention further provides methods for using these peptides in the diagnosis, prophylaxis and therapy of infections by bacteria that express PNAG such as but not limited to Staphylococci and E. coli. Some antibodies of the invention enhance opsonophagocytic killing and in vivo protection against bacteria that express PNAG such as but not limited to Staphylococci and E. coli. Compositions of these peptides, including pharmaceutical compositions, are also provided, as are functionally equivalent variants of such peptides.

  • Patent number: 10919956
    Abstract: The invention relates to compositions of a deacetylated poly N-acetylated glucosamine (dPNAG) of Staphylococci. The dPNAG may be isolated from natural sources or synthesized de novo. The invention also relates to the use of dPNAG as a vaccine for inducing active immunity to infections caused by Staphylococcus aureus, S. epidermidis, other related coagulase-negative or coagulase-positive Staphylococci, and other organisms carrying the ica (intracellular adhesion) locus. The invention further provides methods of use for antibodies directed to dPNAG, particularly for inducing passive immunity to the same class of infections.
