Definition of tylosin in US English:



  • An antibiotic that is routinely fed to livestock as a growth promoter and that may contribute to antibiotic resistance in humans.

    • ‘Currently, many antibiotics, such as tylosin, penicillin, tetracycline, and gentamicin, are available over the counter to farmers to administer at their discretion to livestock by injection, orally, and as feed additives.’
    • ‘Although the lack of response in performance of heifers fed tylosin during the growing period was unexpected, it is not unique.’
    • ‘Another antibiotic approved for use with livestock, tylosin, is closely related to the family of drugs that includes erythromycin.’
    • ‘However, just as with penicillin and the tetracyclines in the past, vets are now simply prescribing more macrolides generally to make up for the ban on tylosin as a growth promoter.’
    • ‘A similar study by Kao's group identified two genes responsible for overproduction of the antibiotic tylosin.’
