Dave, it would be helpful if you clearly listed the symptoms that you have 
seen in your hives so that we could compare them with the list of symptoms 
that have been agreed to add up to CCD.  It is hard to tell from the 
above.  For one thing 5 cups of corpses wouldn’t be symptomatic of CCD as I 
understand it, but then it might not eliminate the possibility either.  
Also, having read Randy’s articles on Nosema, my understanding is that you 
could have some hives testing negative right next to hives that are loaded 
so you can’t necessarily make a conclusion about all the hives in a yard by 
testing only three hives unless it happens to represent a random and 
statistically significant sample.
