Flagella of Escherichia coli spheroplasts.
Recently, Z. Vaituzis and R. N. Doetsch (J. Bacteriol. 89:1586, 1965) described the relationship between flagellation and motility in penicillin-induced spheroplasts of Salmonella typhimurium, and they concluded that the formation of flagella was dependent upon prior cell wall synthesis. This conclusion has now been confirmed with Escherichia coli (ATCC 13070), the results found being identical...
متن کاملThe role of H4 flagella in Escherichia coli ST131 virulence
Escherichia coli sequence type 131 (ST131) is a globally dominant multidrug resistant clone associated with urinary tract and bloodstream infections. Most ST131 strains exhibit resistance to multiple antibiotics and cause infections associated with limited treatment options. The largest sub-clonal ST131 lineage is resistant to fluoroquinolones, contains the type 1 fimbriae fimH30 allele and exp...
متن کاملUropathogenic Escherichia coli flagella aid in efficient urinary tract colonization.
In the murine model of urinary tract infections (UTI), cystitis by uropathogenic Escherichia coli (UPEC) occurs through an intimate relationship with the bladder superficial umbrella cell entailing cycles of adherence, invasion, intracellular bacterial community (IBC) formation, and dispersal (fluxing) from the intracellular environment. IBC dispersal is a key step that results in the spread of...
متن کاملThree mutations in Escherichia coli that generate transformable functional flagella.
Hydrodynamics predicts that swimming bacteria generate a propulsion force when a helical flagellum rotates because rotating helices necessarily translate at a low Reynolds number. It is generally believed that the flagella of motile bacteria are semirigid helices with a fixed pitch determined by hydrodynamic principles. Here, we report the characterization of three mutations in laboratory strai...
متن کاملCoordination of flagella on filamentous cells of Escherichia coli.
Video techniques were used to study the coordination of different flagella on single filamentous cells of Escherichia coli. Filamentous, nonseptate cells were produced by introducing a cell division mutation into a strain that was polyhook but otherwise wild type for chemotaxis. Markers for its flagellar motors (ordinary polyhook cells that had been fixed with glutaraldehyde) were attached with...
