I'm skeptical
I would definitely want to see the research. I'm interested to see how they calculated the likeliness of the patients death.
That said, it has been proven over and over again that the overuse and incomplete/inappropriate use of antibiotics has directly contributed to the creation of "superbugs".
And caution should definitely be taken before destroying a patients normal flora, who knows what might take over C-dif?
Those are my thoughts anyway
