Swimming Motility Assays of Spiroplasma
Spiroplasma swim in liquids without the use of the bacterial flagella. This small helical bacterium propels itself by generating kinks that travel...

Methods for Studying Swimming and Surface Motilities in Rhizobia
Rhizobia are soil proteobacteria able to establish a nitrogen-fixing interaction with legumes. In this interaction, rhizobia must colonize legume...

Outer membrane protein of OmpF contributes to swimming motility, biofilm formation, osmotic response as well as the transcription of maltose metabolic genes in Citrobacter werkmanii
Bacterial outer membrane proteins (Omps) are essential for environmental sensing, stress responses, and substance transport. Our previous study...

Diversity in the swimming motility and flagellar regulon structure of uropathogenic Morganella morganii strains
In current times, the opportunistic pathogen Morganella morganii is increasingly becoming a cause of urinary tract infections. The condition has been...

Methods to Analyze Motility in Eury- and Crenarchaea
Many archaea display swimming motility in liquid medium, which is empowered by the archaellum. Directional movement requires a functional archaellum...

Motility mediates satellite formation in confined biofilms
Bacteria have spectacular survival capabilities and can spread in many, vastly different environments. For instance, when pathogenic bacteria infect...

Motility of Acinetobacter baumannii: regulatory systems and controlling strategies
AbstractAcinetobacter baumannii is a Gram-negative opportunistic zoonotic pathogenic bacterium that causes nosocomial infections ranging from minor...
-
Bacterial motility: machinery and mechanisms
Bacteria have developed a large array of motility mechanisms to exploit available resources and environments. These mechanisms can be broadly...

Analysis of Adhesion and Surface Motility of a Spirochete Bacterium
Spirochetes are Gram-negative bacteria with helical or flat wave morphology and move using flagella residing beneath the outer membrane. Most...

Motility and size of rotifers as risk factors for being consumed by the passive protistan predator Actinosphaerium sp.
Predation is a well-known factor that structures rotifer communities. However, the role of protists as predators is relatively understudied. Here, we...
