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 کاملIn silico fusion of epsilon and beta toxin genes of Clostridium perfringens types D and B
Fusion protein technology represents the strategy to achieve rapid, efficient, and cost-effective proteinexpression. Epsilon and Beta toxins are the most potent Clostridial toxins and cause disease in animals.This study describes in silico fusion of Clostridium perfringens types D and B epsilon and beta toxin genesthat was used for cloning in E.coli. The etx and cpb genes were...
متن کاملClostridium Perfringens Toxin Types Associated with Meat: Review in Iran
Food poisoning due to Clostridium perfringens (C. perfringens) is a major food health problem, particularly in terms of meat consumption. Due to human’s susceptibility to this pathogen, detection methods and prevention measures should be implemented to reduce its incidence. Several pathogenic strains of C. perfringens have been identified so far. One of the potential concerns about this bacteri...
متن کاملToxin plasmids of Clostridium perfringens.
In both humans and animals, Clostridium perfringens is an important cause of histotoxic infections and diseases originating in the intestines, such as enteritis and enterotoxemia. The virulence of this Gram-positive, anaerobic bacterium is heavily dependent upon its prolific toxin-producing ability. Many of the ∼16 toxins produced by C. perfringens are encoded by large plasmids that range in si...
متن کاملGlycosylating Toxin of Clostridium perfringens
Clostridium perfringens type C strains that produce various toxins cause hemorrhagic noxious ulceration or mucousal necrosis of the small intestine in humans, pigs, cattle and chickens (Sakurai et al. 1997, Sakurai and Nagahama 2006). In humans, the bacteria cause necrotic enteritis, which is termed “pig-bel” (Sakurai and Nagahama 2006). C. perfringens has been classified into five types, A to ...
