No, it isn't - even the data published in "Science" (09/2007) shows
that Nosema ceranae ALONE has been found in many hives that did not
show CCD symptoms.  What was striking was that every hive showing CCD
symptoms tested positive for BOTH Nosema apis and Nosema ceranae,
and this correlation was better than the correlation between CCD
and IAPV that was the focus of the paper.

Peter thereby explains in his own words why reports of new cases 
of CCD dropped off during the summer months when nectar and pollen 
were in good supply, as a good bloom can make even the sickest 
hives look much better.

What I don't know is if anyone has any data that contradicts my
little theory about "Nosema apis + Nosema ceranae = CCD", but
I am honor-bound to do my best to kill this idea before it grows 
legs and starts wandering around.  :)

That specific speculation was utterly refuted only weeks later by 
the very next set of samples they pulled out of the refrigerator.
