They actually screen *and* pasteurize usually. It does change the nutrients somewhat and removes many of the immune factors, but since a lot of milk banks are primarily for premature babies and other infants in the NICU they tend to be super cautious. It is still far, far easier for an infant to digest and obtain nutrition from than any other source, which is particularly a concern with extra-fragile infants.
Pasteurization will kill pretty much any microbes of concern if done properly, regardless of the mammal from which the milk originated. It will not, however, probably remove or neutralize any problematic medication that transfers into the milk. (There aren't many that do in quantities sufficient to be an issue for most newborns, let alone anyone older, and I have the list generally used as a guideline by lactation related professionals. This reminds me, however, that I need to tactfully screen for that.)
It will also make the milk spoil much more quickly than raw milk does (as it removes the factors that inhibit bacterial growth), hence ideally it would be pasteurized close to the point it was actually turned into ice-cream.
I personally wouldn't consider pasteurized milk from any mammal to be a form of fluid bonding, but folks might want to consider their own comfort levels and definitions.
