Gram-positive bacterial pili: structures, assembly and function

Pili in Gram - positive pathogens

| Most bacterial pathogens have long filamentous structures known as pili or fimbriae extending from their surface. These structures are often involved in the initial adhesion of the bacteria to host tissues during colonization. In Gram-negative bacteria, pili are typically formed by non-covalent interactions between pilin subunits. By contrast, the recently discovered pili in Gram-positive pat...

Type IV pili in Gram-positive bacteria.

Type IV pili (T4P) are surface-exposed fibers that mediate many functions in bacteria, including locomotion, adherence to host cells, DNA uptake (competence), and protein secretion and that can act as nanowires carrying electric current. T4P are composed of a polymerized protein, pilin, and their assembly apparatuses share protein homologs with type II secretion systems in eubacteria and the fl...

Synthesis, characterization and antimicrobial properties of CuO nanoparticles against gram-positive and gram-negative bacterial strains

Nano structured materials have wide range of applications due to their interesting size-dependent chemical and physical properties compared to particles of size in the range of micrometer. Copper oxide nano materials are of interest on account of their potential uses in many technological fields. In this study  CuO nanoparticles were synthesized via simple sol gel method using basic CuSO4<...
