兔大肠杆菌耐药性调查

Investigation on the Resistance to Rabbit Antibiotics of E.Coli

从璧山、铜梁、荣昌、渝北的4个区县的6个兔场18只病兔中采集病料,分离出6株细菌。镜检、动物试验、生化鉴定及药敏试验证明,分离细菌属于致病性大肠杆菌。药敏试验结果是,6株菌对丁胺卡那霉素、阿奇霉素敏感,对氨苄青霉素、先锋Ⅳ、先锋Ⅴ、氟苯尼考、庆大霉素、复方磺胺、四环素、卡那霉素都有不同程度的耐药性。

Six strains of bacteria were isolated from 18 of Rabbits fed in Bishan,Tongliang,Rongchang and Yubei counties in Chongqing respectively. All the bacteria isolated were identified to E. coli by Glam staining and microscope observation, animal pathogenic test, biochemical characteristics. Six strains E. coli showed susceptibility to amikacin and azithromycin , however, resistance to ampicillin, cefalexin, cefazolin, florfenicol, gentamicin, sulfamethoxydiazine, tetracycline, kanamycin.
