“…These genes harbour resistance to tetracyclines ( tet36, tetA, tetQ, tetG, tetW, tetX, tetT, tetL, tetM ), aminoglycosides ( aadA5, aadA1, strB, aadA2, aadA9 ), sulfonamides ( sul1, sul2 ), trimethoprim ( dfrA1 ), florfenicol ( floR ), antibiotics from MLSB group ( lnuB, mefA ) heavy metals ( merA ), as well as MGEs ( IntI1, intI2, tnpA, tnpA, IS1247 ), and genes encoding the MDR phenotype ( qacEdelta1 ). All of the listed genes harbour resistance to antibiotic groups commonly used in both veterinary and medical treatments (Zalewska and Popowska, 2020).…”
