| 摘 要： | 对来源于广东省珍禽养殖场的3株珍珠鸡源大肠杆菌进行了形态特征、培养特性、生化特性、药敏特性和致病性鉴定，同时对16S rRNA序列进行比较分析。结果发现3株分离茵均对珍珠鸡有较强致病性，但是3株细菌对乳糖、棉子糖、蔗糖、赖氨酸的利用存在差异，对庆大霉素、青霉素、红霉素、环丙沙星、四环素、利福平和氟哌酸等药物的敏感性存在...

| Abstract: | The morphological character,cultural character,biochemical characteristic,drug sensitivity and pathogenicity of three Escherila coli strains isolated from guinea-fowl farms of Guangdong province were detected and the 16S rRNA of these strains were compared.The results showed that three strains were pathogenic to guinea fowls.The fermentation to lactose,raffinose,sucrose and lysine were different.The sensitivity to gentamicin,penicillin,erythrocin,ciprofloxacin,tetracycline,rifampicin and orfloxacin were dif... |
