The isolation of beta haemolytic streptococci was compared using Columbia sheep blood agar with and without gentamicin in a final concentration of 5.5 micrograms per ml. The inclusion of gentamicin gave greatly improved results whenever the isolation of this organism in pure culture was complicated by overgrowth with Gram-negative bacilli or staphylococci.
使用含有和不含终浓度为每毫升5.5微克庆大霉素的哥伦比亚绵羊血琼脂对β溶血性链球菌进行分离比较。每当在纯培养物中分离这种微生物因革兰氏阴性杆菌或葡萄球菌过度生长而变得复杂时,加入庆大霉素会使结果有显著改善。
