Clostridium perfringens epsilon toxin mutant Y30A-Y196A as a recombinant vaccine candidate against enterotoxemia
Epsilon toxin (Etx) is a β-pore-forming toxin produced by Clostridium perfringens toxinotypes B and D and plays a key role in the pathogenesis of enterotoxemia, a severe, often fatal disease of ruminants that causes significant economic losses to the farming industry worldwide. This study aimed to determine the potential of a site-directed mutant of Etx (Y30A-Y196A) to be exploited as a recombi...
متن کاملcloning and expression of clostridium perfringenstype d vaccine strain epsilon toxin gene in e. coli as a recombinant vaccine candidate
background and objectives: clostridium perfringens, a gram-positive obligate anaerobic bacterium, is able to form resistant spores which are widely distributed in the environment. c. perfringens is subdivided into five types a to e based on its four major alpha, beta, epsilon and iota toxins. the aim of the present study was cloning and expression of c. perfringens type d vaccine strain epsilon...
متن کاملFunctional analysis of neutralizing antibodies against Clostridium perfringens epsilon-toxin.
The Clostridium perfringens epsilon-toxin causes a severe, often fatal illness (enterotoxemia) characterized by cardiac, pulmonary, kidney, and brain edema. In this study, we examined the activities of two neutralizing monoclonal antibodies against the C. perfringens epsilon-toxin. Both antibodies inhibited epsilon-toxin cytotoxicity towards cultured MDCK cells and inhibited the ability of the ...
متن کاملNaturally acquired antibodies against Clostridium perfringens epsilon toxin in goats.
Clostridium perfringens type D-producing epsilon toxin is a common cause of death in sheep and goats worldwide. Although anti-epsilon toxin serum antibodies have been detected in healthy non-vaccinated sheep, the information regarding naturally acquired antibodies in ruminants is scanty. The objective of the present report was to characterize the development of naturally acquired antibodies aga...
