Detection of Chicken-derived Escherichia coli in Qingdao Area

从青岛平度、即墨、莱西3个地区的多家养殖场中分离了鸡源大肠杆菌89株,并进行了鉴定及药敏试验。结果表明,所调查地区鸡源大肠杆菌耐药性较严重,对恩诺沙星、氨苄西林耐药最为普遍,其次是氟苯尼考、庆大霉素与环丙沙星。同时发现,调查地区大肠杆菌耐药谱广且多重耐药性严重。

89 strains ofchicken-derived Escherichiacoli were isolated from sevealfams in Qingdao（P ） ingdu, Jimo, Laixi）, and identification am d^g sensitivty test wrere carried out.The results showed that the Escherichia coli resistance of chickens in the investigation area was serious, and the resistance to enrofloxacin and ampicillin was the most common, followed by florfenicol, gentamicin and ciprofloxacin.
