▪ Abstract Flagellated bacteria, such as Escherichia coli, swim by rotating thin helical filaments,
each driven at its base by a reversible rotary motor, powered by an ion flux. A motor is …

IT is widely agreed that bacteria swim by moving their flagella, but how this motion is
generated remains obscure 1,2 . A flagellum has a helical filament, a proximal hook, and …

" This book is a lucid, straightforward introduction to the concepts and techniques of statistical
physics that students of biology, biochemistry, and biophysics must know. It provides a …

The structure of the rotary motor was described in Chapter 9 (Fig. 9.3) and its assembly was
discussed in Chapter 10. Here, I will say more about function. Given that the diameter of the …

Bacteria have developed a large array of motility mechanisms to exploit available resources
and environments. These mechanisms can be broadly classified into swimming in aqueous …

Knowing how motile bacteria move near and along a solid surface is crucial to understanding
such diverse phenomena as the migration of infectious bacteria along a catheter, biofilm …

Statistical fluctuations limit the precision with which a microorganism can, in a given time T,
determine the concentration of a chemoattractant in the surrounding medium. The best a cell …

We studied the migration through semisolid agar of chemotactic and nonchemotactic cells of
Escherichia coli. While swarms of nonchemotactic cells were generally smaller than those …

MOTILE cells of Escherichia coli aggregate to form stable patterns of remarkable regularity
when grown from a single point on certain substrates. Central to this self-organization is …

SOME microorganisms swim well in solutions containing viscous agents (molecules with long
unbranched chains, such as methylcellulose) 1–7 . Leptospira, a slender helical bacterium…
