Tylosin (Tylosin A) is a macrolide antibiotic found naturally as a fermentation product of Streptomyces fradiae. Tylosin exerts potent antimicrobial activity against Gram-positive bacteria. Tylosin is widely used as a feed additive for promoting animal growth. Tylosin is used for veterinary purposes against bacterial dysentery and respiratory diseases in poultry, pigs and cattle.
