We all know about feces splattered hives, but is there a low cost 
test to confirm an infection of nosema apis or nosema cerana?

The goal here is a positive ID to then treat with Fumidil/fumigillin. 
I'm presuming the same treatment will work well on both forms of nosema.

Also, does the USDA lab at beltsville now do a routine check for 
nosema apis and nosema cerana on samples submitted by beekeepers?
