Controversy exists on veterinary drug application in food animal production and the relevance for human health of antimicrobial resistant commensals isolated from food. The aim of this study was to analyze antimicrobial resistance in Escherichia coli isolated from retail meat of various animal species (including wild roe deer) in Austria. Our results were analyzed taking into consideration the current practices of Austrian veterinarians with regard to their use of antibiotic drugs during pig, poultry, and beef production. Resistant isolates were found most often in pork (76%) followed by poultry (63%) and beef (40%). On wild deer carcasses purchased from Austrian hunters only one isolate was found to be resistant. The latter indicates that antimicrobial resistance is not yet an environmental problem in animals living in the wild. The common use of tetracyclines in veterinary medication in various animal species is clearly reflected in the incidence of antimicrobial resistant isolates in commensal E. coli. The intensive use of fluoroquinolones in poultry could explain the high numbers of nalidixic acid resistant isolates found on poultry meat. Our findings partly explain the impact of veterinary drug application on the resistance development of E. coli isolated from meat.
在食用动物生产中使用兽药以及从食品中分离出的具有抗菌抗性的共生菌对人类健康的影响存在争议。本研究的目的是分析从奥地利各种动物物种(包括野生狍)的零售肉类中分离出的大肠杆菌的抗菌抗性。我们在考虑奥地利兽医在猪、家禽和牛肉生产过程中使用抗生素药物的现行做法的情况下对结果进行了分析。抗性菌株最常出现在猪肉中(76%),其次是家禽(63%)和牛肉(40%)。在从奥地利猎人处购买的野生鹿 carcasses 上,仅发现一株菌株具有抗性。后者表明抗菌抗性在野生环境中的动物中尚未成为一个环境问题。在各种动物物种的兽药中普遍使用四环素,这在共生大肠杆菌中抗菌抗性菌株发生率上得到了明显体现。在家禽中大量使用氟喹诺酮类药物可以解释在家禽肉上发现的大量对萘啶酸具有抗性的菌株。我们的研究结果部分解释了兽药应用对从肉类中分离出的大肠杆菌抗性发展的影响。
