.BEE-L posting 001627 reported that:-
" USDA DISCOVERS NEW CONTROL FOR FOULBROOD
Recently a new chemical has been identified that controls
American Foulbrood (AFB) Disease according to an article by Dr.
Shimanuki in the October American Bee Journal. It is interesting
to note that the discovery was based on the relationship between
chalkbrood and AFB. In studies conducted in the 60's, 70's and
80's by the USDA Beltsville Bee Lab they noticed that as the
incidence of chalkbrood increased the incidence of European
Foulbrood decreased.
Later, scientists isolated a substance from chalkbrood that
inhibited the growth of both American and European Foulbrood
bacteria in laboratory studies. A chemist at the lab identified
the active ingredient as linoleic acid. Field tests are now being
conducted to determine the best way to treat colonies of bees."
What was the outcome of these field tests? Does anyone know? I have seen nothing reported in either the scientific literature or beekeeping press.
