Good question. I can't recall the dates, but your estimate sounds about
right.

That is not what I claimed. I said fairly quickly and in the context where
we don't know
1.) the exact date of the ban
2.) the date that beekeepers actually stopped using it, especially on
particularly stubborn cases in nurse yards not producing honey and
3.) we do not know the exact date that resistance appeared.
the interlude looks to me to be short in comparison the previous long period
of antibiotic efficacy while sulfa was in widespread use.
As I recall, the first reports of OTC resistance came from Argentina, then
Florida. Some of the history is in our archives at WWW.BEE-L.ORG (Check out
the new URL)
How long did it take to realise that some AFB was resistant and to
investigate and report it? Several years, I suspect.
> And how widespread is this resistance? Not seeing it here.
It seems to be under control, due to better bees, burning, radiation, and
the use of Tylosin combined.
In my search for dates I cam up with this gem. I am too busy to read it
properly, but it looks good. Enjoy.
