Abstract
The activity of penicillin alone and combined with aminoglycoside on endocarditis strains of streptococci was examined. Good assay reproducibility was obtained by the use of logarithmic phase cultures standardised by opacity, careful inoculation of well-plates, removal of antibiotic by membrane transfer and incubating survival counts in hydrogen plus carbon dioxide. The use of 10-fold intervals for penicillin concentration simplified assay design without loss of efficiency.
摘要
研究了青霉素单独使用以及与氨基糖苷类联合使用对链球菌心内膜炎菌株的活性。通过使用经浊度标准化的对数期培养物、小心接种微孔板、通过膜转移去除抗生素以及在氢气加二氧化碳中培养存活计数，获得了良好的测定重现性。青霉素浓度采用10倍间隔使用简化了测定设计且不损失效率。
