Type IV pili are remarkably strong, flexible filaments with varied roles in bacterial
pathogenicity. All Gram-negative bacterial surfaces have type IV pili, which are polymeric …

▪ Abstract Natural competence is widespread among bacterial species. The mechanism of
DNA uptake in both gram-positive and gram-negative bacteria is reviewed. The …

SUMMARY Type IV pili (T4P) are surface-exposed fibers that mediate many functions in
bacteria, including locomotion, adherence to host cells, DNA uptake (competence), and …

Type IV pili are filaments on the surfaces of many Gram-negative bacteria that mediate an
extraordinary array of functions, including adhesion, motility, microcolony formation and …

Neisseria meningitidis, an exclusive pathogen of humans, remains the leading worldwide
cause of meningitis and fatal sepsis, usually in otherwise healthy individuals. In recent …

Neisseria gonorrhoeae, the Gram‐negative aetiological agent of gonorrhoea, is one of many
mucosal pathogens of man that expresses competence for natural transformation …

The surface of Gram-positive and Gram-negative bacteria contains long hair-like
proteinaceous protrusion known as pili or fimbriae. Historically, pilin proteins were …

Type IV pili (Tfp) are a unique class of multifunctional surface organelles in Gram‐negative
bacteria, which play important roles in prokaryotic cell biology. Although components of the …

Gram-negative bacteria express a wide variety of organelles on their cell surface. These
surface structures may be the end products of secretion systems, such as the hair-like fibers …

The mucosa is colonized with commensal Neisseria. Some of these niches are sites of
infection for the STD pathogen Neisseria gonorrhoeae (Ngo). Given the antagonistic …
