Role of plasmid-encoded adherence factors in adhesion of enteropathogenic Escherichia coli to HEp-2 cells.
Plasmid-encoded adherence factors have been shown to be important for the full expression of enteropathogenic Escherichia coli (EPEC) pathogenicity and for EPEC adhesion to cultured HEp-2 cells. EPEC strain E2348 (O127) shows localized HEp-2 cell adhesion and possesses a 60-megadalton plasmid, pMAR2. When E2348 is cured of pMAR2 it loses the ability to adhere to HEp-2 cells, while nonadherent E...
متن کاملInhibition of enteropathogenic Escherichia coli (EPEC) adherence to HEp-2 cells by bovine colostrum and milk.
BACKGROUND enteropathogenic Escherichia coli (EPEC) is the main etiological agent of infantile diarrhea in Brazil and other developing countries. Human milk IgA protects newborn intestinal mucosa by inhibiting bacterial adhesion to epithelial cells and this effect is shown by in vitro assays of EPEC adhesion to HEp-2 cultured cells. Bovine milk, if effective in promoting this protection, could ...
متن کاملAdherence patterns of diarrheagenic Escherichia coli strains isolated from children with gastrointestinal diarrhea and matched controls in a Hep-2 cell adhesion assay
In the present study, carbon species including organic carbon (OC), elemental carbon (EC), and water-soluble organic carbon (WSOC) concentration in PM2.5 were assessed at an urban site of Tehran, Iran during March to June 2014. The PM2.5 samples were collected using an frmOMNITM Ambient Air Sampler. Thermal gravimetric analysis (TGA) was used to analyze OC and EC. The results showed that PM2.5 ...
متن کاملAggregative adherence fimbriae I of enteroaggregative Escherichia coli mediate adherence to HEp-2 cells and hemagglutination of human erythrocytes.
Strains of enteroaggregative Escherichia coli (EAggEC) have been implicated in several studies as important agents of persistent diarrhea among infants in the developing world. We have previously shown that the aggregative adherence (AA) property of EAggEC is associated with the presence of a 60-MDa plasmid which confers AA when introduced into E. coli HB101. Here, we report the cloning of the ...
متن کاملAdherence factors in atypical enteropathogenic Escherichia coli strains expressing the localized adherence-like pattern in HEp-2 cells.
Although atypical enteropathogenic Escherichia coli (aEPEC) strains are frequently implicated in childhood diarrhea in developing countries, not much is known about their adherence properties. The phenotypic and genotypic characterization of 29 aEPEC strains expressing the localized adherence-like pattern points toward the involvement of E. coli common pilus (ECP), intimins, and other known E. ...
