What do you think might be causing the CCD M. tubule damage/ What would be
your guess?

The sample size was too small to drew any conclusions. What reported is an 
observation. The question of CCD and M. Tubules is a big question 
considering all pathogens and stressors found in these hives. The bee 
venom shut down the guessing centre in my brain! I examine some bees. I 
hope that If I find M. Tubules with symptoms as described, we will analyze 
the "Kidney stones!" to find out if they are oxalate or something else.
