Here's the quote and link from a little pre surgery DD I did this morning.
"There are many examples of bioactive antibacterial coatings that are placed on top of an implant surface that have active antibacterial properties. One example of this is when the implant surface is cross-linked with a bioactive molecule such as human b-defensin-3. Recent studies on the antimicrobial peptide human b-defensin-3 show that it has the capacity to reduce the number of bacterial colonies that accumulate on titanium surfaces and can be effective against resistant organisms such as methicillin-resistant Staphylococcus epidermidis (MRSE) and methicillin-resistant Staphylococcus aureus (MRSA) (30, 31)."
