Think I understand that!

Are you talking about CCD colonies that had died out completely, or ones 
with some survivors?
If the former then it is surprising and clearly suggests other factors are 
present (given that acetic acid fumigation is effective against such a wide 
range of pathogens on comb, that should eliminate many from your 
invetigations?).
If the latter then I would not expect as great an effect if the survivors 
are put on to clean comb, as they will obviously be carrying some nosema 
unless treated with fumidil at the same time.
