Peter posts: " the association between N. ceranae
and poor health of  A. mellifera colonies may simply represent
reporting bias; a novel disease  organism in moribund colonies will be
understandably publicised whereas it  may go unsampled and unnoticed
if it does not have a marked pathological  effect on its novel host." by

We  stated in our article that seeing Nosema plus  virus  in all of the CCD 
operations that we sampled could be a  consequence rather than a cause of a 
collapse.   The novel  disease organism that we found belongs to a group of 
viruses that typically have  a covert phase that is hard to detect and that 
does not have a marked  pathological effect on its hosts, whereas patent 
infections are almost  invariably lethal.  
 
We're conducting inoculation tests with whole colonies.
