Lysostaphin-coated catheters eradicate Staphylococccus aureus challenge and block surface colonization

Lysostaphin is an endopeptidase that kills Staphylococcus aureus, a predominant organism in catheter-related infections. Lysostaphin-coated catheters prevented catheter colonization by several strains of S. aureus, and activity was maintained for at least 4 days. Prophylactic use of lysostaphin in catheters may help prevent the occurrence of catheter-related staphylococcal infections.
