METHODS AND COMPOSITIONS RELATED TO IMMUNIZING AGAINST STAPHYLOCOCCAL LUNG DISEASES AND CONDITIONS

摘要

Embodiments of the invention include methods and compositions useful in a vaccination strategy capable of neutralizing Hla to provide immunoprotection against S. aureus pneumonia. In certain aspects the invention includes a Hla with reduced toxicity, represented by a recombinant mutant form of Hla (HlaH35L) in which histidine 35 is convened to leucine, which can be used to abrogate the productive assembly of the toxin and protect a subject from staphylococcal pneumonia.
