【摘要】 用pH9.6葡萄糖肉汤加6.5％NaCl琼脂和分别单独使用6.5％NaCl琼脂及3％—5％羊血琼脂三种不同培养基,从同一份样品中初代分离肠球菌,初代分离率有显著差别。pH9.6葡萄糖肉汤加6.5％NaCl琼脂分离法可对检样选择性增菌和选择性分离,其检出率明显高于现在普遍使用于肠球菌初代分离的3％—5％血琼脂平板(P<0.05),也高于单纯使用6.5％NaCl琼脂平板(P<0.05);后两者间无显著差别(P>0.05);属中种的构成用不同初代分离方法检出情况也不同。”更多还原

【Abstract】 We isolated Enterococcus primarly for the same samples with glucose broth (pH9. 6)abb 6. 5% NaCl agar,6. 5%NaCl a-gar and 3%-5% sheep blood agar respectively ?The results showed that:using glucose broth (pH9. 6,as a selecive-enrichment medium) culturing samples,and then using 6. 5,% NaCl a gar to isolate Enterococcus whithan isolated rate abviously higher than those isokted with blood agar (P<0. 05>or 6. 5%NaCl a-gar(p<0. 05) respectively ?The differences were not found be tween blood agar and 6. 5% NaCl agar (P<0. 05). Sone of Enterococcus spp. that can be isokted from the three methods were different更多还原
