Significance Bacterial migration, aggregation, and even host infection depend on the generation of mechanical force. Despite their biomedical importance, forces between bacteria and surfaces have not yet been measured during migration. We present a first study of bacterial cell–substrate traction using Myxococcus xanthus as a model organism. M. xanthus exhibits two common mechanisms of motility, namely, twitching and gliding. We find that these mechanisms lead to distinct patterns of traction…

Mechanomicrobiology: how bacteria sense and respond to forces
How microbiology and biophysics are converging to advance the understanding of the mechanobiology of microorganisms is discussed and bacterial phenotypes influenced by mechanical inputs, including adhesion, motility and biofilm formation are explored.
Mechanosensing of shear by Pseudomonas aeruginosa leads to increased levels of the cyclic-di-GMP signal initiating biofilm development
It is shown that bacteria can sense shear and can respond by initiating biofilms, an important advance in fundamental microbiology and mechanobiology and points the way to a hitherto-undeveloped type of antibiofilm surface that thwarts mechanosensing by not sustaining sufficiently high shear.
Pseudomonas aeruginosa distinguishes surfaces by stiffness using retraction of type IV pili
The results suggest that stiffness sensing in much smaller bacterial cells relies on temporal sensing instead of spatial sensing strategies, and this connection between pathogenicity and mechanical properties of the infection site presents an interesting potential for clinical applications.
Competitive binding of independent extension and retraction motors explains the quantitative dynamics of type IV pili
The strong quantitative agreement of this model with a variety of experiments suggests that the entire repetitive cycle of pilus extension and retraction is coordinated by the competition of stochastic motor binding to the pilus machine, and that the retraction motor is the major throttle for pilus production.
Traction force microscopy with optimized regularization and automated Bayesian parameter selection for comparing cells
This work systematically test the performance of new methods from computer vision and Bayesian inference for solving the inverse problem in TFM, and finds that Elastic Net regularization, which combines L1 and L2Regularization, outperforms all other methods with regard to accuracy of traction reconstruction.
Thermosynechococcus switches the direction of phototaxis by a c-di-GMP dependent process with high spatial resolution
Insight is provided into previously undescribed rapid bacterial polarity regulation via second messenger signalling with high spatial resolution and it is revealed that rod-shaped cells can move perpendicular to the light vector, indicating that the polarity can be controlled not only by pole-to- pole regulation but also within-a-pole regulation.
Thermosynechococcus switches the direction of phototaxis by a c-di-GMP-dependent process with high spatial resolution
Insight is provided into previously undescribed rapid bacterial polarity regulation via second messenger signalling with high spatial resolution into type IV pilus-dependent cell movement in the rod-shaped thermophilic cyanobacterium Thermosynechococcus vulcanus using optical microscopy.
Type IV pili: dynamics, biophysics and functional consequences
A comprehensive understanding is emerging of the molecular architecture of the T4P machinery and the filament it builds, providing mechanistic insights into the assembly and retraction processes.
Motor Properties of PilT-Independent Type 4 Pilus Retraction in Gonococci
It is proposed that bacteria encode for retraction ATPases when T4P have to generate high force supporting functions like twitching motility, triggering host cell response, or fluidizing colonies.


Molecular Microbiology
This review summarises the control of bacteriophage A. development, placing particular attention to the mechanisms involved in the "lysis or lysogeny" decision and the regulation of replication of phage A., as well as of plasmids derived from this phage.

It is shown that the full set of hydromagnetic equations admit five more integrals, besides the energy integral, if dissipative processes are absent, which made it possible to formulate a variational principle for the force-free magnetic fields.
