I've heard of it but the sites you gave added a lot to the little knowledge I have of it. Thanks.
While I think it is really a worthy method against bacterial infections, and thus, something that can really be useful for antimicrobial resistant infections, I think that our immune system can handle any bacterial infection. There cannot be any resistance developed to the way our immune system tackles bacteria. The problem is that our immune systems are not up to the task because of wrong diet, wrong living, and drugs (particularly NSAIDs).
One thing I find strange: with the mechanism of action already known, I wonder why there still is a call for "studies"? Studies for what? Effectivity? The mechanism clearly shows the effectivity. And previous usage (even before penicillin?) has also shown it to be effective. Safety? Again, the mechanism shows it would not affect mammalian cells, so what's there to study? I think this is just another effect of the AMA/FDA instigation that I brought up in another thread. There's no money in it for them at the moment, so they would want to milk out all they can by imposing a "research" requirement.
Or the drug companies are just looking for a way to patent a virus or two.
I haven't studied the sites fully, and I plan to look further on the topic, but would you know if these phages are as indiscriminate as antimicrobials? that is, will they also kill beneficial microorganisms? or are they specific to certain species of bacteria?
