A paracrystalline surface layer (S layer) was found as the outermost layer of the cell wall of five Mycobacterium bovis BCG strains. An oblique arrangement of the subunits in the S layer was only clearly seen in thin-sectioned and shadowed preparations, and the unit constant was about 5.5 nm.
在五株卡介苗细胞壁的最外层发现了一层类晶体表面层(S层)。S层中亚基的倾斜排列仅在超薄切片和投影制备物中清晰可见,单位常数约为5.5纳米。
