Immunogenicity of a Fusion Protein Comprising Coli Surface Antigen 3 and Labile B Subunit of Enterotoxigenic Escherichia coli
Background: Enterotoxigenic Escherichia coli (ETEC) strains are the major causes of diarrheal disease in humans and animals. Colonization factors and enterotoxins are the major virulence factors in ETEC pathogenesis. For the broad-spectrum protection against ETEC, one could focus on colonization factors and non-toxic heat labile as a vaccine candidate. Methods: A fusion protein is composed of a...
متن کاملProduction, Purification and Characterization of Chicken Egg Yolk Monoclonal Antibody Against Colonization factor antigen -1 of Enterotoxigenic Escherichia coli Causing Diarrhea
Enterotoxigenic Escherichia coli (ETEC) causes diarrhea in both humans and animals. The contaminated food and water are the most common vehicles for ETEC infection. The colonization factor antigen (CFA-1) is a fimbriae protein that promotes adherence of the ETEC strain to the epithelium of the small intestine of the host. In this study IgY proteins were produced against the CFA-1 of ETEC in imm...

متن کاملEvolutionary and functional relationships of colonization factor antigen i and other class 5 adhesive fimbriae of enterotoxigenic Escherichia coli.
Colonization factor antigen I (CFA/I) is the archetype of eight genetically related fimbriae of enterotoxigenic Escherichia coli (ETEC) designated class 5 fimbriae. Assembled by the alternate chaperone pathway, these organelles comprise a rigid stalk of polymerized major subunits and an apparently tip-localized minor adhesive subunit. We examined the evolutionary relationships of class 5-specif...
متن کاملA putative, novel coli surface antigen 8B (CS8B) of enterotoxigenic Escherichia coli
Enterotoxigenic Escherichia coli (ETEC) strains harbor multiple fimbriae and pili to mediate host colonization, including the type IVb pilus, colonization factor antigen III (CFA/III). Not all colonization factors are well characterized or known in toxin positive ETEC isolates, which may have an impact identifying ETEC isolates based on molecular screening of these biomarkers. We describe a nov...
