Without getting too convoluted in who said what when please refer to:

Mr Fisher references  the paper “A Metagenomic Survey of Microbes 
in Honey Bee Colony Collapse Disorder” (“Science”, 09/06/07)

and says

" Although the authors dismissed Nosema as a possible correlating factor for CCD, 
their tests found Nosema to be surprisingly common.  Nearly universal.  Every 
apiary affected by CCD was found to have Nosema, and 90% of them had both 
types of Nosema at the same time.  Even among apiaries said to be “free of 
CCD”, 92% of them were found to have Nosema ceranae, and 47% of them had 
Nosema apis. " 
  
                          Apiaries                       Apiaries 
                          With CCD                 Free Of CCD 
Nosema apis   90%                         47.6% 
Nosema ceranae 100%                  92.1%
