摘要: The objective of the study was to answer question whether ready-to-eat meat products can pose indirect hazard for consumer health serving as reservoir Enterococcus strains harboring tetracyclines, aminoglycosides, and macrolides resistance genes. A total 390 samples were investigated. found in 74.1% samples. 302 classified as: faecalis (48.7%), faecium (39.7%), casseliflavus (4.3%), durans (3.0%), hirae (2.6%), other spp. (1.7%). high percentage isolates resistant streptomycin level (45%) followed by erythromycin (42.7%), fosfomycin (27.2%), rifampicin (19.2%), tetracycline (36.4%), tigecycline (19.9%). ant(6')-Ia gene most frequently (79.6%). Among genes that encode aminoglycosides-modifying enzymes, highest portion had aac(6')-Ie-aph(2'')-Ia (18.5%) aph(3'')-IIIa (16.6%), but from food is also an effect presence aph(2'')-Ib, aph(2'')-Ic, aph(2'')-Id Resistance tetracyclines associated with tetM (43.7%), tetL (32.1%), tetK (14.6%), tetW (0.7%), tetO (0.3%) ermB ermA 33.8% 18.9% isolates, respectively. Nearly half contained a conjugative transposon Tn916/Tn1545 family. Enterococci are widely present retail products. Many isolated (including such species E. casseliflavus, durans, hirae, gallinarum) antibiotic carry transferable
