Bacteria have developed a large array of motility mechanisms to exploit available resources
and environments. These mechanisms can be broadly classified into swimming in aqueous …

The bacterial flagellum is a helical filamentous organelle responsible for motility. In bacterial
species possessing flagella at the cell exterior, the long helical flagellar filament acts as a …

Fluorescence microscopy is an invaluable tool in the biosciences, a genuine workhorse
technique offering exceptional contrast in conjunction with high specificity of labelling with …

Bacteria predate plants and animals by billions of years. Today, they are the world's smallest
cells, yet they represent the bulk of the world's biomass and the main reservoir of nutrients …

Many bacteria swim in liquid or swarm over solid surfaces by synthesizing rotary flagella.
The same bacteria that are motile also commonly form nonmotile multicellular aggregates …

Campylobacter jejuni is the leading cause of bacterial diarrhoeal disease in many areas of
the world. The high incidence of sporadic cases of disease in humans is largely due to its …

Optical tweezers (OT) have emerged as an essential tool for manipulating single biological
cells and performing sophisticated biophysical/biomechanical characterizations. Distinct …

The ulcer-causing gastric pathogen Helicobacter pylori is the only bacterium known to
colonize the harsh acidic environment of the human stomach. H. pylori survives in acidic …

The flagellum and the injectisome are two of the most complex and fascinating bacterial
nanomachines. At their core, they share a type III secretion system (T3SS), a transmembrane …

Mechanosensing by flagella is thought to trigger bacterial swarmer-cell differentiation, an
important step in pathogenesis. How flagellar motors sense mechanical stimuli is not known …
