The unique paradigm of spirochete motility and chemotaxis

…, MR Miller, MA Motaleb, CW Wolgemuth - Annual review of …, 2012 - annualreviews.org
… motors that run CW in the default state should reverse and rotate CCW under a high CheY3-P
concentration, and those motors that run CCW in the default state should run CW. Perhaps …

[PDF][PDF] Collective swimming and the dynamics of bacterial turbulence

CW Wolgemuth - Biophysical journal, 2008 - cell.com
To swim, a bacterium pushes against the fluid within which it is immersed, generating fluid
flow that dies off on a length scale comparable to the size of the bacterium. However, in dense …

Bacterial swimming and oxygen transport near contact lines

…, C Dombrowski, CW Wolgemuth… - Proceedings of the …, 2005 - National Acad Sciences
Aerobic bacteria often live in thin fluid layers near solid–air–water contact lines, in which the
biology of chemotaxis, metabolism, and cell–cell signaling is intimately connected to the …

Flagellar motility of the pathogenic spirochetes

CW Wolgemuth - Seminars in cell & developmental biology, 2015 - Elsevier
Bacterial pathogens are often classified by their toxicity and invasiveness. The invasiveness
of a given bacterium is determined by how capable the bacterium is at invading a broad …

[PDF][PDF] Cytoskeletal cross-linking and bundling in motor-independent contraction

SX Sun, S Walcott, CW Wolgemuth - Current Biology, 2010 - cell.com
Eukaryotic and prokaryotic cells use cytoskeletal proteins to regulate and modify cell shape.
During cytokinesis or eukaryotic cell crawling, contractile forces are generated inside the …

[HTML][HTML] Live imaging reveals a biphasic mode of dissemination of Borrelia burgdorferi within ticks

…, MJ Caimano, U Pal, CW Wolgemuth… - The Journal of …, 2009 - Am Soc Clin Investig
Lyme disease is caused by transmission of the spirochete Borrelia burgdorferi from ticks to
humans. Although much is known about B. burgdorferi replication, the routes and …

Theory of swimming filaments in viscoelastic media

HC Fu, TR Powers, CW Wolgemuth - Physical review letters, 2007 - APS
Motivated by our desire to understand the biophysical mechanisms underlying the swimming
of sperm in the non-Newtonian fluids of the female mammalian reproductive tract, we …

Twirling and whirling: Viscous dynamics of rotating elastic filaments

CW Wolgemuth, TR Powers, RE Goldstein - Physical Review Letters, 2000 - APS
Motivated by diverse phenomena in cellular biophysics, including bacterial flagellar motion
and DNA transcription and replication, we study the overdamped nonlinear dynamics of a …

Swimming speeds of filaments in nonlinearly viscoelastic fluids

HC Fu, CW Wolgemuth, TR Powers - Physics of Fluids, 2009 - pubs.aip.org
Many micro-organisms swim through gels and non-Newtonian fluids in their natural
environments. In this paper, we focus on micro-organisms which use flagella for propulsion. We …

Z-ring force and cell shape during division in rod-like bacteria

G Lan, CW Wolgemuth, SX Sun - Proceedings of the …, 2007 - National Acad Sciences
The life cycle of bacterial cells consists of repeated elongation, septum formation, and division.
Before septum formation, a division ring called the Z-ring, which is made of a filamentous …
