Enterobacterial fimbriae.
Many different species of the family Enterobacteriaceae have been shown to possess fimbrial appendages which emerge from the bacterial cell as straight, rigid organelles distinct from flagella (14). The role of fimbriae (synonym: pili) as adhesins in both enterotoxigenic and uropathogenic isolates of Escherichia coli has been demnonstrated, and thus the identification of such appendages as viru...
متن کاملVolunteer challenge with enterotoxigenic Escherichia coli that express intestinal colonization factor fimbriae CS17 and CS19.
Human challenges with enterotoxigenic Escherichia coli (ETEC) have broadened our understanding of this important enteropathogen. We report findings from the first challenge studies using ETEC-expressing colonization factor fimbria CS17 and CS19. LSN03-016011/A (LT, CS17) elicited a dose-dependent effect, with the upper dose (6 × 10(9) organisms) causing diarrhea in 88% of recipients. WS0115A (L...
متن کاملThe major pilin subunit of the AAF/II fimbriae from enteroaggregative Escherichia coli mediates binding to extracellular matrix proteins.
Enteroaggregative Escherichia coli (EAEC) adherence to human intestinal tissue is mediated by aggregative adherence fimbriae (AAF); however, the receptors involved in EAEC adherence remain uncharacterized. Adhesion to extracellular matrix proteins is commonly observed among enteric pathogens, so we addressed the hypothesis that EAEC may bind to extracellular matrix proteins commonly found in th...
متن کاملPorphyromonas gingivalis fimbriae
Marginal periodontitis is not a homogeneous disease but is rather influenced by an intricate set of host susceptibility differences as well as diversities in virulence among the harbored organisms. It is likely that clonal heterogeneity of subpopulations with both high and low levels of pathogenicity exists among organisms harbored by individuals with negligible, slight, or even severe periodon...
متن کاملProduction of FaeG, the major subunit of K88 fimbriae, in transgenic tobacco plants and its immunogenicity in mice.
Transgenic tobacco plants stably expressing recombinant FaeG, which is the major subunit and adhesin of K88ad fimbriae, were obtained. Analysis of sera from immunized mice indicates that in mice, the immunogenicity induced by plant-derived FaeG protein is comparable to that generated with traditional approaches.
