I remember many years ago when "the muck" (see archives) turned up in
Australia it was originally thought to be Kashmir Bee Virus (KBV) as it had
been isolated from some of the larvae. It was sent to England and injected
into larvae which died. So it was assumed that what we now know as "the
muck" was KBV and the field symptoms were written up as such. This lead to
some export problems. It wasn't until later when samples sent away did not
yield KBV that it was realised that what we were seeing was not caused by
KBV. It also meant that KBV did not cause the symptoms that had been
published.
What it did show was that if you directly inject the virus into the bee or
larvae, it will die. This is not a natural way and could mean results that
are not accurate as was the case with KBV.
