Molecular Strategies for Fimbrial Expression and Assembly

摘要: Fimbriae or pili are long, filamentous, multimeric macromolecules found on the bacterial cell surface. Bacteria express a diverse array of fimbriae that involved in adherence and invasion. can be categorized based their modes expression assembly. Type I P distributed peritrichously translocated to surface by chaperone/usher pathway. 4 located at pole assembled via type II secretion system. Curli coiled structures an extracellular nucleation/precipitation oral Gram-negative Gram-positive bacteria have not been well-studied as compared with enteric pathogens. Oral pathogens, such Eikenella corrodens, Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis, possess implicated adhesion These potential virulence factors infectious process...
