title: [Structural study of the basal bodies of the flagella of Bacillus brevis var. G.-B. P+].
abstract: The structural organisation of the flagellum basal body was studied in Bacillus brevis var. G.-B. P+ by electron microscopy. It was compared with that of Escherichia coli MS 1350. The basal body of a B. brevis flagellum contains, in addition to two pairs of rings on a rod, another ring-like structure (d = 13.6 nm, h = 4.3 nm) which we referred to as a "collar". The collar makes the basal body of B. brevis different from that of B. subtilis, another Gram-positive bacterium. The collar seems to fasten the flagellum of B. brevis to the cell wall. We have concluded that the basal body can differ not merely among bacterial systematic groups, but also among bacteria belonging to one and the same genus. The role of individual elements in the structure of the basal body of bacterial flagella is discussed.
