abstract：:The structure of sheathed flagella from Bdellovibrio bacteriovorus was investigated. The first three periods of these flagella were characterized by progressively smaller wavelengths and amplitudes in periods more distal to the cell. The damped appearance was due to a single nonrandom transition between two helical st...
