Antibiotic resistant infection treatment

I ran across this article which reports on some research that indicates there is a peptide which can help treat bacterial infections which are resistant to our most effective antibiotics. This is a large and growing problem, but from what I can gather this research is a very long way from being the help we need. The animal experiments which lead to this report were not designed to show infections are actually cured, but rather it appears that if the peptide is given before or shortly after the animals are challenged with bacteria, the enhanced immune system helps prevent infections and affords some protection. Unfortunately, this is a long way from being what we really need.
