As far as treatment goes does it matter whether you have N. ceranae or N. 
apis?  I ask this because it seems like it is a bigger deal to determine 
which one you have than it is to just determine that you have Nosema.  
Also, I wonder if there is a way to test fecal material for Nosema spores. 
It would seem that if you had streaking you would be sure to have Nosema 
spores in the feces if that was the cause of the streaking.  Of course just 
because you don't see streaking it doesn't mean you don't have Nosema.
