Bacteria display an abundance of cellular forms and can change shape during their life
cycle. Many plausible models regarding the functional significance of cell morphology have …

Flagellar motility of Campylobacter jejuni and Helicobacter pylori influences host
colonization by promoting migration through viscous milieus such as gastrointestinal mucus …

Pseudomonas aeruginosa is a Gram-negative bacterium that causes opportunistic infections
in immunocompromised individuals. P. aeruginosa employs a type III secretion system to …

Symbiosis has significantly contributed to organismal adaptation and diversification. For
establishment and maintenance of such host–symbiont associations, host organisms must …

Flagella-driven motility is an important trait for bacterial colonization and virulence. Flagella
rotate and propel bacteria in liquid or semi-liquid media to ensure such bacterial fitness …

Attachment is a necessary first step in bacterial commitment to surface-associated behaviors
that include colonization, biofilm formation, and host-directed virulence. The Gram-negative …

Pseudomonas aeruginosa exhibits swarming motility on 0.5 to 1% agar plates in the
presence of specific carbon and nitrogen sources. We have found that PAO1 double mutants …

Bacterial flagella are highly conserved molecular machines that have been extensively
studied for assembly, function and gene regulation. Less studied is how and why bacteria …

Bacteria differ in number and location of their flagella that appear in regular patterns at the
cell surface (flagellation pattern). Despite the plethora of bacterial species, only a handful of …

Most bacteria in nature live in surface-associated communities rather than planktonic
populations. Nonetheless, how surface-associated environments shape bacterial …
