    mark, is it more feasible to apply the preventative treatments vs. isolating and destroying as it appears?

    Losing popularity? A third antibiotic for AFB has been approved in the last year....Tylan resistance isn't showing up because people aren't using Tylan.

    For who?

    TM is used prophylactically as a preventitive medication by some commercial beekeepers. That doesn't mean they don't have hives w/ active state AFB every now and then. When they do, and find it, they handle it, deal w/ it. It is destroyed when it appears.

    A third one? Terrimycin, Tylosin, and what?

    not seeing anyone doing much afb prevention around here, couldn't say about elsewhere.

    When did this come on the mkt? How is it supposed to be used? How did you hear about it?

    I don't remember where I heard about it. My guess is it's supposed to be used when your AFB won't respond to TM or Tylan anymore.

    Bee Culture;Aug2012, Vol. 140 Issue 8, p75 I think is an article about it?

    I guess I will have to look that up. I haven't heard of any of my friends using it yet. I also have not heard of any AFB which doesn't respond to TM or Tylan. Not that I hear commercial guys talking about treating active state AFB either.

    I think beltsville tests for both kinds of resistance.

    Yes, they do. I have seen many of those reports here in NY. My own and those of others who have had samples sent in to Beltsville.

    I read the article you mentioned and Beltsville worked on getting the antibiotics approved, the one you mentioned and the 4 types of tylosin too. So, maybe we have 6 drugs and not just three.

    This whole resistance thing is confusing to me. I still don't understand whether we would have resistance expressed in the Lab wheteher antibiotics were used or not. I have not used TM in ages and never used it consistantly or across my whole operation. And yet I will have reports of resistance. So, what does that mean to someone who burns cases found and does not treat?

    it means the resistant afb may have been brought in from somewhere else, somewhere that it had the opportunity to become resistant, perhaps by your strong bees robbing out a nearby colony.

    FWIW, I ran the notes I posted here by the PI of the study, just to make sure I wasn't overstating or misstating anything...it passed muster.

    "it means the resistant afb may have been brought in from somewhere else, somewhere that it had the opportunity to become resistant,"

    I understand Monsanto uses a antibiotic as a marker to keep track of ifs roundup ready genes

    This chart from the study is pretty descriptive...in the top part, each color represents a separate antibiotic resistance gene, and in the bottom, you can see the relative amounts.
