"Negative-sense RNA-specific PCR indicated that VDV-1 replicates in the
Varroa synganglion and all other tissues tested, but we could not detect
DWV replicating in any Varroa tissue."
> So he's saying that DWV-A *was not* replicating in varroa.
Not exactly. Absence of proof is not proof of absence. Further, VDV-1 is now considered a form of DWV.
According to Grozinger and Flenniken
DWV-B was originally referred to as VDV-1, but subsequent analysis indicated
that it is a variant of DWV, sharing 84% sequence identity to DWV-A. DWV-B was
originally detected in European A. mellifera populations but has recently been identified in
A. mellifera populations in the United States and Africa.
DWV-B may be increasing in prevalence in managed A. mellifera bee populations. In the United
States, DWV-B prevalence increased dramatically from 2 infected apiaries of 75 tested in 2010 to
161 infected apiaries of 603 tested in 2016. [ten-fold increase]
