But this is the same Canadian Maritimes experiment covered in the Williams
PhD thesis cited before.  Quoting from the thesis on Pg 32:

>> "The work presented in Chapter 5 also appears in:
>> Williams, Shutler, Little, Burgher-MacLellan, Rogers, 2010.
>> "The microsporidian Nosema ceranae, the antibiotic Fumagilin-B(r), and
western
>> honey bee (Apis mellifera) colony strength" Apidologie 42, 15-22."

Aside from this single study, the bulk of the evidence still shows N.
ceranae as a factor in colony survival, and much of it shows that Fumagillin
is highly effective in lab settings, although less effective in field
settings.

The above-quoted thesis is here:

With the key phrase in the summary being "less virulent N. ceranae".
