ESCHERICHIA COLI HEAT-LABILE TOXIN B SUBUNIT: CONSTRUCTION AND EVALUATION OF PLASMIDS PROVIDING CONTROLLED HIGH LEVEL PRODUCTION OF THE PROTEIN
With the plasmid DNA from a clinical isolate of enterotoxigenic Escherichia coli (ETEC) H 10407 as template, PCR-mediated cloning of the sequence encoding the heat-labile toxin B subunit (L T -B) has been carried out. Then this sequence was recloned into the pTrc 99A and pET23a expression vectors to give the pJasmids pTRCLTB and pETLTB, respectively. After induction, the former plasmid provides...
متن کاملConstruction and Expression of a Fused Gene for B Subunit of the Heat-Labile and a Truncated Form of the Heat-Stable Enterotoxins in Escherichia coli
Elaboration of different toxins by enterotoxigenic E. coli has been considered as one of the main virulence factors contributing to the manifestation of disease caused by these microorganisms. Various strategies have been employed to raise antibodies against these toxins as a line of defense. In this study, the 3’ terminus of the gene that codes for the binding subunit of the heat-labile entero...
متن کاملImmunogenicity 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 کاملIsolation of enterotoxigenic and enteroaggregative straines of Escherichia coli from chicken carcasses by PCR
The aim of this study was to determine the frequency of enterotoxigenic and enteroaggregative strains ofEscherichia coli in chicken carcasses by polymerase chain reaction (PCR). In this study 63 strains of E. coliwere isolated from 110 samples of chicken carcasses during processing after chilling in the poultry slaughterhouse of Shahrekord. Polymerase chain reaction assays were used to detect t...
