Abstract
Fifty-six α-hemolytic streptococcal isolates were identified using MALDI Biotyper MS (Bruker Daltonics), API 20 Strep (bioMérieux), and BD Phoenix (Becton, Dickinson). The gold standard for identification was 16S rRNA gene sequence analysis with 16S-23S rRNA intergenic spacer sequencing. The following percentages of isolates were correctly identified to the species level: MALDI Biotyper, 46%; BD Phoenix, 35%; and API 20 Strep, 26%.
摘要
采用 MALDI Biotyper MS（布鲁克·道尔顿）、API 20 Strep（生物梅里埃）和 BD Phoenix（贝克顿·迪金森）对 56 株α-溶血性链球菌进行鉴定。鉴定的金标准是 16S rRNA 基因序列分析结合 16S-23S rRNA 基因间隔区测序。以下为各鉴定方法对种水平的正确鉴定百分比：MALDI Biotyper，46%；BD Phoenix，35%；API 20 Strep，26%。
