The antibacterial action of tylosin adsorbed to fish meat protein was examined. It was found that adsorbed or bound tylosin shows no antibacterial activity and only free tylosin has an antibacterial action.
Thanks are given to Dr. K. OTAYA of Shionogi & Co. for providing samples of tylosin and literatures, and also to Mr. H. TOZAWA of this laboratory for suggestions on experimental methods.
