I suggest reading the current wisdom from Dr. Les Dethlefson, human microbiota researcher at Stanford's Relman lab [0].

In the link he addresses the difference between addressing an acute condition with probiotics versus long-term maintenance of health. Your question seems to land somewhere in the middle. So see what he has to say and please remember, this is far from settled science!
