>The duration of symptoms, however, may be somewhat atypical, since there
have been symptoms since the beginning of april. Providing sufficient
proteins and carbohydrates was not able to resolve the condition.

Sorry to hear, Kris.  I lose few colonies to obvious CBPV--most clear
themselves spontaneously.  Typically good protein and carbs will allow most
colonies to clear most any sort of infection.

Dr. Tom Rinderer's PhD thesis was on breeding bees resistant to CBPV.
There is large variation between colonies.  You may simply have a colony
that is not able to clear the infection.
