CPC classification number: C12Q1/24
Abstract: Methods of the invention include the isolation of intact, viable microorganism(s) from positive blood culture (“PBC”) samples for use in downstream analyses such as identification and antimicrobial susceptibility testing (“AST”). The methods involve collecting a portion of the PBC sample, adding a choline-containing solution, lysing the blood cells, isolating the viable microorganism, and performing downstream analysis of the isolated, viable microorganism. The methods can be applied to a variety of gram-positive bacteria, gram-negative bacteria, and/or yeast, and particularly to strains of S. pneumoniae.
Abstract translation: 本发明的方法包括从用于下游分析如鉴定和抗微生物敏感性试验（AST）的阳性血培养（PBC）样品中分离完整的活的微生物。 所述方法包括收集一部分PBC样品，加入含胆碱的溶液，裂解血细胞，分离活微生物，以及进行分离的活的微生物的下游分析。 该方法可以应用于各种革兰氏阳性细菌，革兰氏阴性细菌和/或酵母，特别是肺炎链球菌菌株。

Abstract: Various embodiments disclosed herein provide for reagents and methods for rapidly isolating viable microbial cells, including S. pneumoniae, from positive blood culture samples. The resulting microbial pellet can be used for both identification and growth-based methods such as antimicrobial susceptibility testing. The buffers described herein may contain a base solution, non-ionic detergents, thiols, and optionally, ammonium chloride. The disclosed methods provide a process for rapidly isolating and concentrating viable microorganism(s) from PBC samples using only one sample preparation tube and centrifugation while removing cellular debris from the mammalian blood cells that may interfere with identification methods.
