Tylosin

Tylosin is a macrolide antibiotic produced by S. fradiae that has bacteriostatic activity against Gram-positive bacteria. It is a mixture of tylosin A, B, C, and D, with tylosin A contributing 80% of its bacteriostatic activity. Tylosin has MIC values of 9.6, 16.4, 0.1, 1, and 0.5 µg/ml for F. necrophorum, A. pyogenes, M. gallisepticum, S. aureus, and S. uberis, respectively.,, Formulations containing tylosin have been used for the prevention of liver abscesses in cattle. Tylosin is an environmental contaminant because it is not fully metabolized by treated livestock and enters the environment through manure-based fertilizers.CAS Number: 1401-69-0.
