hi,
 
Its more than likely that tylosin will restrict or kill the vegitative stage
of AFB but why use something which is twice if not more expensive than
Tetracycline (Terramycin).  I beleive that Tetracycline is the only legal
product that you can use in USA.
 
Furthermore, the dosage may not be well documented, and the effect of tylosin
on the brood should be checked out!
 
Perhaps Brenda Ball could tell us a lot more ?
