Campylobacter jejuni cytolethal distending toxin mediates release of interleukin-8 from intestinal epithelial cells.
Live cells of Campylobacter jejuni and Campylobacter coli can induce release of interleukin-8 (IL-8) from INT407 cells. Additionally, membrane fractions of C. jejuni 81-176, but not membrane fractions of C. coli strains, can also induce release of IL-8. Membrane preparations from 81-176 mutants defective in any of the three membrane-associated protein subunits of cytolethal distending toxin (CD...
متن کاملDetection of cytolethal distending toxin (cdt) Genes in Campylobacter jejuni and Campylobacter coli isolated from the intestinal of commercial broiler chickens, turkey and quail of Iran
Background: Campylobacter jejuni and Campylobacter coli are zoonotic bacteria which are frequently associated with human diarrhea. Sharing of the cytolethal distending toxin (cdt) genes in Campylobacter is common and is considered species specific. OBJECTIVES: In this study we focused on detecting the presence of cdt gene in C. jejuni and C. coli isolated from broilers, turkeys and quails of Ir...

متن کاملCholesterol depletion reduces entry of Campylobacter jejuni cytolethal distending toxin and attenuates intoxication of host cells.
Campylobacter jejuni is a common cause of pediatric diarrhea worldwide. Cytolethal distending toxin, produced by Campylobacter jejuni, is a putative virulence factor that induces cell cycle arrest and apoptosis in eukaryotic cells. Cellular cholesterol, a major component of lipid rafts, has a pivotal role in regulating signaling transduction and protein trafficking as well as pathogen internali...
متن کاملCytolethal distending toxin genes in Campylobacter jejuni and Campylobacter coli isolates: detection and analysis by PCR.
Campylobacter jejuni produces a toxin called cytolethal distending toxin (CDT). Knowledge of the prevalence and homogeneity of Campylobacter sp. cdt genes is incomplete. In this work, we identified four PCR primer pairs that collectively amplified cdt genes in all of the C. jejuni and Campylobacter coli strains tested. Restriction analyses of the cdt PCR products showed clear differences betwee...
