Ian,
Thanks for the information.
As for pathogen levels, what the study cannot show is whether the higher pathogen load was involved in the cause of CCD or was a result of CCD, according to vanEngelsdorp. Higher pathogen loads are likely to have caused CCD symptoms, but what causes the bees to become infected with so many pathogens is still not known, he added.
Regards,
Ernie
