【摘要】 从保定、秦皇岛、北京3个地区鸡场怀疑患大肠杆菌病的病、死鸡的肝脏、心包等组织中分离鉴定出38株大肠杆菌。按世界卫生组织(WHO)推荐的Kirby-Bauer菌液涂布法对38株大肠杆菌进行24种抗生素的药物敏感性试验,结果表明:38株大肠杆菌均有不同程度的耐药,而且均表现多重耐药;较为敏感的抗生素是头孢菌素类和氨基糖苷类抗生素,其中以阿米卡星、头孢唑啉、头孢拉定、头孢哌酮和头孢三嗪最为敏感;对青霉素类抗生素、林可胺类抗生素、四环素类抗生素和大环内酯类抗生素耐药严重,其中以麦迪霉素、林可霉素、氨苄青霉素、四环素和阿莫西林耐药性最为严重;药物敏感试验为保定、秦皇岛和北京三个地区养鸡业提供科学的用药指南,为药物防治提供科学依据。更多还原

【Abstract】 38 isolates of Escherichia coli(E.coli) were isolated from chickens either ill or dead suspected with E.coli from chicken breeding farms in Baoding、Qinhuangdao、Beijing areas.the results of the antibiotics sensitivity test of 38 isolates to 24 kinds antibiotics show that all isolates have presented antibiotic resistance disparately as well as multi-resistance.All isolates are sensitive to Cephalosporins antibiotics and Aminoglycosides antibiotics such as Amikacin,Cefazolin,Cefradine,Cefoperazone,and Ceftriaxone. Thirty-eight isolates are extremely resistant to Penicillins antibiotics,Lincomycins antibiotics,Tetracyclines antibiotics and Macrolides antibiotics such as Midecamycine,Lincomycin,Carbenicillin,Tetracycline, Amoxicillin and so on.Antibiotics sensitivity test provides guidance for antibiotic application and scientific foundation from poultry farms.更多还原
