If I understand what I read, OTC changes bees gut microbiota and leaves them susceptible to other problems.
Anyone else read this? Comments?

OTC is oxytetracycline. I think I've seen the cousins south of the 49th refer to Tylosin. Same stuff I think. Correct me if that's a mistake.
Typically used to treat for EFB and AFB. In commercial ops, allegedly in a proactive and pre-emptive regime. I can not say, do not know, will not judge. Not walking in those shoes.
This may flange up with the threads regarding requirements to have vets provide prescriptions.
I honestly don't know if it does.

No, Tylosin and OTC are not the same thing.

Tylosin tartrate, sold under the name Tylan. It is used to cure OTC resistant AFB. Tylosin is not used as a preventative for AFB, and it is not used to treat EFB. IIRC, residues can persist for several months after using it. For all intents and purposes, if you use it on a hive, wait until next year before harvesting honey from that hive.

Oxytetracycline (OTC) is a broad spectrum antibiotic that is used to cure AFB or EFB, and is also used as a preventative for AFB. The withdrawal period for OTC is something like 6 weeks.
