Yes. This is pretty interesting and looks, from my quick scan, to be good
work. I also note the word, "excessive" is used, not "any" to modify
"treatment".
From my cursory examination the conclusions appear to be based on direct
applications of bacteria to larvae, and even oral application. I was not
clear on how that was accomplished I had limited time for in-depth
analysis.
I am also not sure that this proves that not using antibiotics will actually
reduce chalkbrood in an actual working hive.
At any rate, I don't think any of us dispute that there are beneficial and
harmful activities by microflora and microfauna going on in any given hive,
or that suppressing one or giving another an advantage may upset whatever
balance exists, in the short run, at least.
All this is interesting and worth knowing, but I wonder how significant the
disruption due to medications -- if applied necessarily and judiciously --
actually is in the real world. I recall Andy said that beekeepers he knew
applied oxytet regularly because the bees just thrived better, and it was
obvious.
I realize that perfectionists and extremists may argue that no disruption in
any hive is justified, but most of us keep bees for the economic benefit and
there is reduced or no benefit from maintaining bees which break down with
foulbrood, and that is sometimes the alternative to treatment.
I think, also, that most thinking people question whether
a.) the natural state of any particular hive is intrinsically optimal
b.) it is not possible to improve that state by manipulations, treatments
and other means
c.) where pathology is obvious or likely, that measures should not be made
to remedy or forestall the problem
d.) the economic health of the beekeeper trumps other considerations
I think it is all a matter of perspective, and commercial migratory
beekeepers are going to think and act very differently than stationary and
hobbyist beekeepers or those who keep bees for philosophical reasons and
make decisions based on theory or hypotheses.
All in all, it seems that this is a question of theory and idealism vs.
necessity and practice. What is obvious in a lab or research setting may
have little or no importance on a commercial setting, or be trumped by
larger considerations.
Besides, we can deal with chalkbrood very easily. Just get better bees.
In summary, my position is that all the above does not negate the importance
and interest of the studies cited, but we do have to balance many
conflicting forces, and this consideration is just one.
And the word is "excessive", after all.
