New structural features of the flagellar base in Salmonella typhimurium revealed by rapid-freeze electron microscopy.

Abstract

The structure of the flagellar base in Salmonella typhimurium has been studied by rapid-freeze techniques. Freeze-substituted thin sections and freeze-etched replicas of cell envelope preparations have provided complementary information about the flagellar base. The flagellar base has a bell-shaped extension reaching as far as 50 nm into the bacterial… (More)
