Physicochemical characterization of the staphylolytic LysK enzyme in complexes with polycationic polymers as a potent antimicrobial.

Staphylococcus aureus causes many serious visceral, skin, and respiratory diseases. About 90% of its clinical strains are multi-drug resistant, but the use of bacteriophage lytic enzymes offers a viable alternative to antibiotic therapy. LysK, the phage K endolysin, can lyse S.
