Peter, can't support that statement.  There are many who would not agree,
including some of the foremost researchers who have studied carefully.

Bob, I did follow a yard that was in the 5-10M range for three years.  Did
not observe any relationship between survival, buildup, or honey production
and N ceranae levels.

However, as I said, I saw higher spore counts on my truck net samples this
spring than ever before.  Deplorably, I have yet to find time to test
individual colonies, but hope to soon (should have splits finished by the
weekend).
