摘要
2006年10月—2008年5月,从国内5个省的9个规模型鸭场的发病鸭或死亡鸭分离、鉴定大肠杆菌67株,采用肉汤稀释法测定其对头孢3代、4代,碳青霉烯类、单环β-内酰胺环类和氟喹诺酮类药物的敏感性。结果表明,试验菌株对以上药物的耐药率分别为头孢曲松钠(56.7%)、头孢噻呋(71.6%)、头孢吡肟(31.3%)、头孢噻肟(49.3%)、左氧氟沙星(50.7%)、环丙沙星(71.6%)、加替沙星(62.7%)、亚胺培南(0%)、氨曲南(56.7%),鸭致病性大肠杆菌的耐药性比较严重,且同类药物的交叉耐药不容忽视。
Specimens were collected from sick or dead ducks from 9 aquatic farms of 5 provinces in China. 67 suspected strains were purified and then identified by VITEK-32 as E. coli. The results of bacterial susceptibility experiments by the broth micro-dilution test indicated that the tested bacteria presented 56.7%, 71.6%, 31.3%, 49.3%, 50.7%, 71.6%, 62.7%,0% and 56.7% resistance to Ceftriaxone Sodium, Ceftiofur, Cefepime, Cefotaxime, Levofloxacin, Ciprofloxacin, Gatifloxacin, Imipenem, Aztreonam, respectively. The resistant condition of the duck E. coli to the above-mentioned drugs was severely and cross-resistance between analogues should not be neglected.
