Personally, I would burn the frame with the infection, because there a
zillions of spores on it.  If the rest of the frames are not yet infected, or
if they only have a cell or two, I would medicate repeatedly.  You'll have to
stop honey production, of course.
Keep a close watch.  Some hives will clean up infection. Others seem
susceptible, no matter how much they are medicated. It has to do with their
natural trait of good housekeeping.
 
One more thing.  I would make certain that it is actually foulbrood.  If you
put a frame above the excluder in a hive that was a bit weak, and there were
some cold nights following, the brood may have gotten chilled and died, or
gotten stressed and had a lot of chalkbrood or European foulbrood break out.
 Make certain it actually is American foulbrood.
 
If it is one of the stress diseases, it would also be a good idea to requeen.
The weakness that makes them susceptible is genetic. It might also help with
AFB.
