Tryptophan content of Clostridium perfringens epsilon toxin.
The tryptophan content of Clostridium perfringens epsilon toxin was investigated. When the tryptophan content was determined by amino acid analysis after the hydrolysis of epsilon prototoxin with methanesulfonic acid containing 3-(2-aminoethyl)indole and by the spectrophotometric method with N-bromosuccinimide, the number of tryptophan residues was calculated at 1/mol of the protein. Cleavage o...
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 Epsilon Toxin Increases the Small Intestinal Permeability in Mice and Rats
Epsilon toxin is a potent neurotoxin produced by Clostridium perfringens types B and D, an anaerobic bacterium that causes enterotoxaemia in ruminants. In the affected animal, it causes oedema of the lungs and brain by damaging the endothelial cells, inducing physiological and morphological changes. Although it is believed to compromise the intestinal barrier, thus entering the gut vasculature,...
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...
متن کاملClostridium perfringens epsilon-toxin increases permeability of single perfused microvessels of rat mesentery.
Epsilon-toxin, the primary virulence factor of Clostridium perfringens type D, causes mortality in livestock, particularly sheep and goats, in which it induces an often-fatal enterotoxemia. It is believed to compromise the intestinal barrier and then enter the gut vasculature, from which it is carried systemically, causing widespread vascular endothelial damage and edema. Here we used single pe...
