What are the alternative treatments in patients with multidrug-resistant bacterial strain infections? Could such treatments (eg, phage therapy) offer a chance for cure in such patients?
Mark Loeb: It is a theoretical possibility. The problem is outside of antibiotics there are no good clinical trials. Most of the phage studies are anecdotal. They have been talked about for some time now, and I am certainly not seeing really large-scale clinical trials showing direct benefit, and maybe that is what is required. It may be something in the future but is not quite ready yet.
