In broilers, resistance percentages were the lowest (P\u200a\u2264\u200a0.01) in the latest time period. A significant decrease in MDR over time was also observed for broilers and a tendency for a decrease for pigs. Resistance to meropenem and tigecycline was absent, and resistance to azithromycin was 0.2%\u20132.0%. Also, low resistance to third-generation cephalosporins (1.1%\u20137.4%) was detected in broilers. Resistance to colistin varied between 0.1%\u20134.8%. E. coli from broilers showed high resistance to ciprofloxacin (7.3%\u201323.3%), whereas for cattle and pigs this was 0.2%\u20132.5%. Low\/moderate resistance to chloramphenicol (9.3%\u201321.3%) and gentamicin (0.9%\u20137.0%) was observed in pigs and broilers. The highest resistance was noted for ampicillin (32.7%\u201365.3%), tetracycline (41.3%\u201367.5%), trimethoprim (32.0%\u201335.7%) and trimethoprim\/sulfamethoxazole (27.5%\u201349.7%) from pigs and broilers, with marked country differences.
