Classification of bacterial motility using machine learning [PDF]

, 2020
Cells can display a diverse set of motility behaviors, and these behaviors may reflect a cell’s functional state. Automated, and accurate cell motility analysis is essential to cell studies where the analysis of motility pattern is required.

Differential Dynamic Microscopy of Bacterial Motility

Physical Review Letters, 2011
4 pages, 4 figures. In this updated version we have added simulations to support our interpretation, and changed the model for the swimming speed probability distribution from log-normal to a Schulz distribution.

Effects of surface passivation on gliding motility assays [PDF]

, 2010
In this study, we report differences in the observed gliding speed of microtubules dependent on the choice of bovine casein used as a surface passivator.

Differential Gene Expression of Three Mastitis-Causing Escherichia coli Strains Grown under Planktonic, Swimming, and Swarming Culture Conditions

mSystems, 2016
Bacterial motility is thought to play an important role in virulence. We have previously shown that proficient bacterial swimming and swarming in vitro is correlated with the persistent intramammary infection phenotype observed in cattle. However, little

Helicobacter pylori FlhB function: the F1hB C-terminal homologue HP1575 acts as a "Spare part" to permit flagellar export when the HP0770 FlhB(CC) domain is deleted [PDF]

, 2006
In Helicobacterpylori 26695, a gene annotated HP1575 encodes a putative protein of unknown function which shows significant similarity to part of the C-terminal domain of the flagellar export protein FlhB.

A Comprehensive Genetic Characterization of Bacterial Motility

PLoS Genetics, 2005
We have developed a powerful experimental framework that combines competitive selection and microarray-based genetic footprinting to comprehensively reveal the genetic basis of bacterial behaviors. Application of this method to Escherichia coli motility identifies 95% of the known flagellar and chemotaxis genes, and reveals three dozen novel loci that,

Swarming and complex pattern formation in Paenibacillus vortex studied by imaging and tracking cells [PDF]

, 2008
Background Swarming motility allows microorganisms to move rapidly over surfaces. The Gram-positive bacterium Paenibacillus vortex exhibits advanced cooperative motility on agar plates resulting in intricate colonial patterns with geometries that are ...

RABiTPy: an open-source Python software for rapid, AI-powered bacterial tracking and analysis

BMC Bioinformatics
Bacterial tracking is crucial for understanding the mechanisms governing motility, chemotaxis, cell division, biofilm formation, and pathogenesis. Although modern microscopy and computing have enabled the collection of large datasets, many existing tools

Bacterial Biohybrid Microswimmers

Frontiers in Robotics and AI, 2018
Over millions of years, Nature has optimized the motion of biological systems at the micro and nanoscales. Motor proteins to motile single cells have managed to overcome Brownian motion and solve several challenges that arise at low Reynolds numbers.

Gastrointestinal Motility Disorders and Their Clinical Implications in Cirrhosis

Gastroenterology Research and Practice, 2017
Gastrointestinal motility is impaired in a substantial proportion of patients with cirrhosis. Cirrhosis-related autonomic neuropathy, increased nitric oxide production, and gut hormonal changes have been implicated.
