Determinants Influencing Polar Flagellar Biosynthesis and Cell Division in Campylobacter jejuni
… and spatial parameters for amphitrichious flagellation. Two factors that have been identified to control flagellar placement and numbers in polarly-flagellated bacteria are the FlhF GTPase and the FlhG ATPase. FlhF has been shown to be required for regulation of flagellar gene expression …

Identification of the Polar Flagellum Genes in Azospirillum brasilense
… grasses. This organism has a mixed pattern of flagellation: a single polar flagellum for motility in liquid medium and lateral flagella which might be involved in motility across the root surface and or attachment to the root hairs of plants. Flagella dictate <em>A. brasilense</em> chemotactic …

Following Sayyida Zaynab: Twelver Shi‘ism in Contemporary Syria
… Ayatollah ‘Ali Khamenei have called the bloody flagellation practices, which have only increased in popularity in Sayyida Zaynab over the past few decades, ‘backward’ and ‘irrational.’ Why do these outsiders condemn these Twelver Shi‘is and their Muharram rituals? Why are ‘traditional’ practices …

The Characterization of Quorum Sensing E. Coli Regulators E,F, and G (Qse EFG) and Their Role in Pathogenesis
… to regulate transcription. This pathway for flagellation and motility, which allows EHEC to be motile, has been well-characterized and involves the two-component sytem QseBC. Less is known about the signaling towards EHEC's AE lesion formation capability. Here, we describe a unique signaling …

The little engine that could: Characterization of noncanonical components in the speed-variable flagellar motor of the symbiotic soil bacterium Sinorhizobium meliloti
… was nearly as abysmal as those without FliL but flagellation was essentially normal indicating distinct roles for the two proteins. FliL is implicated in initial stator recruitment to the motor while MotF was found to serve as a power or speed modulator. A model to accommodate and explain the …

Colonization dynamics of oro-gastrointestinal microbes critical to infant health
… a dose-dependent manner. It was concluded that flagellation with FliC mediates direct interactions between neighboring C. sakazakii ATCC 29544 cells which promote autoaggregation. Further experiments utilizing animal models will need to be conducted to determine if autoaggregation in C. …

In situ Metabolism and Biogeography of Phototrophic Consortia
… For the first time, the monopolar monotrichous flagellation of the central bacterium could be visualized. In situ, intact motile "P. roseum" consortia were strongly attracted by sulfide and 2-oxoglutarate, which indicated a potential role of these compounds in the metabolism of "P. roseum". In …
