Side-by-side comparison of H serotyping and MS-H typing of E. coli H types with the Orbitrap platforma.

-, serotyping titration or MS identification was not reached.aSerotyping and MS-H were performed concurrently from subcultures of single bacterial colonies. MS-H was repeated on two consecutive days; bmotility induction was performed for these inconsistent strains after initial MS-H; cuntypeable by serotyping although previous MS and PCR-based sequencing showed type H21; dusing designated antisera by MS-H.- 未完成血清分型滴定或质谱（Mass Spectrometry, MS）鉴定。 a 血清分型与MS-H同步从单菌落的传代培养物中实施，且连续两日重复开展MS-H检测； b 初始MS-H检测完成后，针对结果不一致的菌株实施动力诱导实验； c 尽管此前质谱与基于PCR的测序结果显示为H21型，但血清分型无法确定该菌株型别； d 采用MS-H指定的抗血清。
