There is at least one condition that self proclaimed experts have
declared to be "the rottenest case of AFB I've ever seen." The
samples on this tested negative. The condition was cleared up by
requeening. The puzzler on this one was that the queen from the
afflicted colony was in two cases put into another hive with different
bees and the resulting colony built up normally from that point.
There was no more "disease" in either the original sick colony or the
old queens new domain.
