background: in this study, the presence of resistance to diclazuril, amprolium+ethopabate and salinomycin, representing some of the commonest anticoccidials in iran’s poultry industry, against three mixed eimeria field isolates were investigated. methods: three eimeria field isolates, collected from typical broiler farms in iran, were propagated once, inoculated to 480 broilers, comprising 30 c...
Tetrahydropyran rings are a common feature of complex polyketide natural products, but much remains to be learned about the enzymology of their formation. The enzyme SalBIII from the salinomycin biosynthetic pathway resembles other polyether epoxide hydrolases/cyclases of the MonB family, but SalBIII plays no role in the conventional cascade of ring opening/closing. Mutation in the salBIII gene...
A confirmatory, highly selective multi-residue method based on liquid chromatography coupled to hybrid high resolution mass spectrometry (LC-Q-Orbitrap) was developed and validated for the determination of 12 regulated coccidiostats in eggs muscle. Particularly, ionophore antibiotics (lasalocid, maduramicin, monensin, narasin, salinomycin semduramicin) synthetic (diclazuril, halofuginone, nicar...
