Chris wrote that the group had not measured the nosema spores.
I am wondering if this might be a way forward. N. ceranae spores are 4.7
+/- 0.46 microns in length (Fries 1996), whereas N. apis is approx 1 micron
longer. Apparently there is only a slight overlap, so measuring a number
(define?) of spores should be a reliable method of diagnosis. A simple
graticule in the eyepiece of a compound microscope (1000x would probably be
better than 400x) should be all that is needed.
