Cloning of Clostridium perfringens iota toxin gene in Escherichia coli
Iota toxin is produced by Clostridium perfringens type E. This toxin causes antibiotic-associated enterotoxemia in lambs and calves. Iota toxin is a binary toxin that has two components including Ia (the enzyme component) and Ib (the binding component). Ib binds to the surface receptor of target cells and translocate Ia into the cytosol of cells. The aim of this study was to clone toxigenic epi...
متن کاملCloning and expression of an adhesin (AIDA-I) involved in diffuse adherence of enteropathogenic Escherichia coli.
The adherence of enteropathogenic Escherichia coli (EPEC) to the small bowel mucosa is an important step in the pathogenesis of diarrheal diseases. It has been shown that many EPEC strains adhere to HEp-2 and especially HeLa cells in characteristic patterns termed localized adherence (LA) and diffuse adherence (DA). A plasmid-derived DNA fragment encoding a factor specific for LA hybridized onl...
متن کاملMolecular cloning of mycobacterial promoters in Escherichia coli.
Mycobacterium bovis BCG chromosomal DNA, digested with EcoR1 and HindIII, was used to construct a promoter library in Escherichia coli using the promoter probe plasmid pKO-1. DNA inserts of various sizes showed promoter activity judged by the level of galactokinase (galK) whose synthesis they activate (between 50 and 850 galactokinase units). No correlation between the length of the DNA insert ...
متن کاملMolecular Characterization and Antimicrobial Resistance of Uropathogenic Escherichia coli
Background:Urinary Tract Infections (UTIs) are the most common infectious diseases in childhood. The Uropathogenic Escherichia coli (UPEC) strains account for as much as 80% of UTIs. Objective:From a clinical perspective, it is important to know which virulence factors and antibiotic resistance properties are present in UPEC strains in pediatrics. Therefore, this study was carried out...
متن کاملRegulatory Interactions among adhesin gene systems of uropathogenic Escherichia coli.
Uropathogenic Escherichia coli strain J96 carries multiple determinants for fimbrial adhesins. The regulatory protein PapB of P fimbriae has previously been implicated in potential coregulatory events. The focB gene of the F1C fimbria determinant is highly homologous to papB; the translated sequences share 81% identity. In this study we investigated the role of PapB and FocB in regulation of th...
