A few days ago when I posted that a solar melter will not sterilize
equipment, I was asked off list for the temperature at which AFB spores
are killed.  I thought this was covered on-list, but was not successful
searching the BEE-L archives.  I was surprised not to find the answer in
_THatHB_ or _ABCs..._ and not even in
_Honey_Bee_Pests,_Predators,_and_Diseases_ by Morse and Nowogrodzki.
 
The closest I could come was that in preparing samples for examination
for AFB one must heat the solution to 80dC to kill non-sporative
bacteria.  The texts did not give the lethal temperature for AFB spores.
 
So now that I've searched the archives and checked three text books I'll
impose a simple (I thought) question on the list.  What is the lethal
temperature for spores of Bacillus larvae (American Foulbrood)?
 
TIA,
Aaron Morris
