Methodological approaches--cryoultratomy and high-voltage electron microscopy of whole cell--have been used for studying the ultrastructural organization of the tuberculous mycobacteria of the virulent H37Rv strain and BCG vaccine strain. The anatomic difference has been found between the virulent and vaccine strains, which can undoubtedly be taken as a strain difference. The presence of a developed lipid capsule sheath has been confirmed and the size of separate mycobacterial species defined more accurately.
已采用方法学手段——冷冻超薄切片术和全细胞高压电子显微镜术——来研究强毒株H37Rv和卡介苗疫苗株结核分枝杆菌的超微结构组织。已发现强毒株和疫苗株之间存在解剖学差异，这无疑可视为菌株差异。已证实存在发达的脂质包膜鞘，并更精确地确定了各分枝杆菌种类的大小。
