Proof of the efficacy of probiotics is pretty mixed. There's only marginal evidence they might be beneficial when taking antibiotics. Many of the bacteria in probiotics fail to establish in the gut. Fecal transplants, on the other hand, show a lot of effectiveness.

Probiotics are not used to establish a healthy flora, but a flora, that wont hurt you.
If there is nothing and intensines are free for colonization you are asking yeast or different bacteria like clostridium to take a hold there.
If it is colonized already, this is harder.
