>What percent fit the CCD description?
* IAPV was, with a single exception, confined to CCD samples, yielding
a positive predictive value of 96.1% and a specificity of 95.2%
* They found Nosema spp. in both CCD and non-CCD operations. The
overall prevalence of any Nosema species was 94.1% (100%, CCD; 85.7%,
non-CCD).
* Neither KBV nor Nosema ceranae contributed significantly to the risk
for CCD nor did they alter the influence of IAPV on CCD.
* They have not proven a causal relationship between any infectious
agent and CCD; nonetheless, the prevalence of IAPV sequences in CCD
operations, as well as the temporal and geographic overlap of CCD and
importation of IAPV infected bees, indicate that IAPV is a significant
marker for CCD.
