Tylosin B, EvoPure® is a highly purified form of tylosin B (desmycosin). Tylosin B is a metabolite of tylosin A and forms in acidic media.
Tylosin is a macrolide antibiotic that was originally isolated from Streptomyces fradiae by the Lilly Research Laboratories in 1961 from a soil sample collected in Thailand. Tylosin is a mixture of four macrolide antibiotics of which the primary component (>80%) is Tylosin A. To a lesser degree, Tylosin B (desmycosin), Tylosin C (macrocin) and Tylosin D (relomycin) may also be present. Tylosin has broad-spectrum bacteriostatic activity against Gram-positive bacteria and mycoplasma, but much less activity against most Gram-negative bacteria and fungi.
Tylosin has been used to study protein synthesis, abscess prevention in cattle, and mycoplasma infections.
