Nothing all that new, just the general over use of antibiotics and the usual problems that follow. mbio has an open access policy so you can read the full article in the link above.
http://mbio.asm.org/content/3/6/e00377-12.fullLong-Term Exposure to Antibiotics Has Caused Accumulation of Resistance Determinants in the Gut Microbiota of Honeybees
We found that 50 years of using antibiotics in beekeeping in the United States has resulted in extensive tetracycline resistance in the gut microbiota. These bacteria, which form a distinctive community present in healthy honeybees worldwide, may function in protecting bees from disease and in providing nutrition. In countries that do not use antibiotics in beekeeping, bee gut bacteria contained far fewer resistance genes. The tetracycline resistance that we observed in American samples reflects the capture of mobile resistance genes closely related to those known from human pathogens and agricultural sites. Thus, long-term treatment to control a specific pathogen resulted in the accumulation of a stockpile of resistance capabilities in the microbiota of a healthy gut. This stockpile can, in turn, provide a source of resistance genes for pathogens themselves. The use of novel antibiotics in beekeeping may disrupt bee health, adding to the threats faced by these pollinators.
How it is related to the article above? Are you thinking that queen could transfer bacterial resistance to tetracycline to her daughters? Are you familiar with Lamarck?but does the person you get your queens from also not use antibiotics?.... but not of much use to me.
I think I did not pay attention to the fact that new queen may introduce bad bacteria via pup. wildbranch2007 I apologize for my "attack". It was not nice. SergeySergey, you should read this study carefully......

A third one? Terrimycin, Tylosin, and what?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.

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 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?
