The Measurement of Bacterial Motility [PDF]
Journal of General Microbiology, 1960 SUMMARY: Bacterial motility was measured by a simple method which consists of counting the number of organisms which pass across a small aperture in a given time. The count is proportional to the bacterial concentration in the suspension and also to the average speed of the bacteria.

Investigating transcription factor dynamics in health and disease using FRAP
FEBS Letters, EarlyView.FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Roles for motility in bacterial–host interactions [PDF]
Molecular Microbiology, 1997 The ability to move in a directed manner may confer distinct advantages upon host‐adapted prokaryotes. Potential benefits of motility include increased efficiency of nutrient acquisition, avoidance of toxic substances, the ability to translocate to preferred hosts and access optimal colonization sites within them, and dispersal in the environment ...

Functional characterization of the transcription factor YjjQ in Escherichia coli [PDF]
, 2013 YjjQ is a FixJ/NarL‐type transcriptional regulator conserved in commensal and various pathogenic bacteria such as enterohaemorrhagic Escherichia coli (EHEC), uropathogenic E. coli (UPEC) as well as Citrobacter and Enterobacter.

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions
FEBS Letters, EarlyView.The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Mechanism of bacterial gliding motility
Nippon Saikingaku Zasshi, 2015 Bacteria have various way to move over solid surfaces, such as glass, agar, and host cell. These movements involve surface appendages including flagella, type IV pili and other "mysterious" nano-machineries. Gliding motility was a term used various surface movements by several mechanisms that have not been well understood in past few decades.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential
FEBS Letters, EarlyView.Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Fluids, 2021 The presence of a nearby boundary is likely to be important in the life cycle and evolution of motile flagellate bacteria. This has led many authors to employ numerical simulations to model near-surface bacterial motion and compute hydrodynamic boundary ...

Running after your host: Stimulation of bacterial motility promotes colonization
, 2021 In this issue of Cell Host and Microbe, Robinson et al. (2021) make elegant use of experimental evolution to demonstrate that increased motility promotes migration toward and colonization of zebrafish larvae by a commensal bacterium.
