Over here we use oxtetracycline,for EFB, but nothing for AFB.
We can use antibiot for hive, but we cannot take honey from that.
I can use it for example that if I have disease after winter, I give medicin and in proper situation I shake bees into foundation hive.
I get rid off disease and medicine residuals too. We have not absolute burning rule. We cannot move hives from site. Vet will order the consept.
We can save bees with shaking but combs is better to burn.
Medicine covers disease for a while and it will burst again.
in USA medicine is meant for prevention. If disease have bursted in the hive (black tar), medicine helps not much because cell are so contaminated with disease.
