"Honeybee colony collapse is a sanitary and ecological worldwide problem. The features of this syndrome are an unexplained disappearance of adult bees, a lack of brood attention, reduced colony strength, and heavy winter mortality without any previous evident pathological disturbances. To date there has not been a consensus about its origins. This report describes the clinical features of two professional bee-keepers affecting by this syndrome. Anamnesis, clinical examination and analyses support that the depopulation in both cases was due to the infection by Nosema ceranae (Microsporidia), an emerging pathogen of Apis mellifera. No other significant pathogens or pesticides (neonicotinoids) were detected and the bees had not been foraging in corn or sunflower crops. The treatment with fumagillin avoided the loss of surviving weak colonies. This is the first case report of honeybee colony collapse due to N. ceranae in professional apiaries in field conditions reported worldwide. "

I question this person's results. Don't get me wrong I would love to think it will be this easy or simple.
BUT nosema ceranae has been around for longer then we thought, samples where pulled from back in late 80's and it was already present.
Yes, it does need to be treated for. Yes it will kill a hive, and you can see it coming from a mile away.

I THINK someone got themselves published. Yep I would believe this bee yard had nosema, they treated for it and yep it improved. BUT did it have CCD hmmmmmm. :rolleyes:

Why is it no other insects touch beehives that have died from CCD? Other bugs love beehives, honey, pollen all in one place. DANG that is a buffet like no other.
Boy I hate to be the cynic. But someone has to or you would believe everything everyone says:p
