摘要: The use of antimicrobials for the control infectious disease has increased in recent decades. Understanding trends antimicrobial resistance provides clues about relationship between and emergence resistance. We examined 540 Escherichia coli isolates to 19 that represent 11 classes agents. were collected from chickens 1993 2013 China. Overall, >96.7% resistant at least one tested compounds, 87.2% them displayed multidrug (MDR) representing five six classes. A high proportion E. tetracycline (90.6%), nalidixic acid (80.6%), ampicillin (77.2%), trimethoprim-sulfamethoxazole (76.9%), streptomycin (72.8%). Only 3.0% nitrofurantoin, none was meropenem. Resistance amikacin, ampicillin, aztreonam, ceftazidime, cefotaxime, cephalothin, chloramphenicol, ciprofloxacin, fosfomycin, levofloxacin, norfloxacin, acid, piperacillin, significantly (P <0.01). There an increasing trend MDR over 20 year period.
