摘  要:
对2株鸭源肠球菌临床分离株和1株粪肠球菌参考菌株的形态特征、培养特性、生理生化特性、对药物的敏感性等生物学特性进行了初步研究。结果表明,3个被检菌株在光学显微镜下呈球形、革兰氏阳性染色和链状排列方式;能在10℃、45℃和6.5%NaCl肉汤等条件下生长,能耐热60℃30min,其特性均符合肠球菌属的特征,各菌株生化反应特性均与粪肠球菌特性基本一致,3个菌株均可鉴定为粪肠球菌。药敏试验结果表明,3个菌株均对青霉素、万古霉素、庆大霉素和左氟沙星高度敏感,而对四环素耐药。

摘  要:
The morphological, cultural characters, biochemistry characters and the drug sensitivity of two enterococcus strains isolated from dying ducks and one reference strain of E. facialis were studied. The three bacteria shared following characteristics: appearing spherical in optical microscope, staining gram-positive; arraying by chain, growing well in broth containing 6.5 % NaCl at 10 and 45 ℃, surviving for 30 min at 60 ℃. Because the biochemical reactions characteristics of all bacteria agree well with those of E. facials, they were all identified as E. facials. Additionally, the results of drug sensitivity tests indicated that all the three strains were sensitive to penicillin, vancomycin, gentamycin and levofloxacin, but resistant to tetracycline.
