Abstract
To determine the optimal media for optochin susceptibility testing of Streptococcus pneumoniae, we measured inhibition zones for 72 S. pneumoniae and 22 Streptococcus viridans isolates on three blood-containing media. Because 15.3, 0, and 22.2% of S. pneumoniae organisms were misidentified on Columbia agar, Trypticase soy agar (TSA), and Mueller-Hinton agar, respectively, each containing sheep blood, we recommend that TSA-sheep blood agar be used.
摘要
为确定用于肺炎链球菌Optochin药敏试验的最佳培养基，我们在三种含血培养基上测量了72株肺炎链球菌和22株草绿色链球菌分离株的抑菌圈。因为分别有15.3%、0%和22.2%的肺炎链球菌菌株在含羊血的哥伦比亚琼脂、胰蛋白酶大豆琼脂（TSA）和Mueller-Hinton琼脂上被误鉴定，所以我们建议使用TSA-羊血琼脂。
